Λύσεις Ασκήσεων – Σειρά Βήμα-Βήμα

Σειρά Βήμα Βήμα από το Skaki64, όλες οι λύσεις των ασκήσεων

Καλωσήρθατε στη σελίδα όπου συγκεντρώνονται όλες οι λύσεις των ασκήσεων της σειράς βιβλίων Βήμα-Βήμα. Εδώ θα βρείτε όλες τις απαντήσεις από όλα τα βιβλία ασκήσεων της σειράς Βήμα-Βήμα.

Εκτός από τις απαντήσεις υπάρχουν και αναλύσεις όταν και όποτε αυτό κρίνεται απαραίτητο, ώστε να γίνεται πιο εύκολα κατανοητή η σωστή απάντηση.

Αυτό είναι ένα σπουδαίο βοήθημα για τους προπονητές, αλλά και όσους προσπαθούν μόνοι τους να μάθουν (αυτοδιδασκαλία). Σε κάθε περίπτωση όμως, η ύπαρξη προπονητή είναι απαραίτητη.

Να σε εμπνεύσει και να σε καθοδηγήσει!

41: Compare / Is the difference decisive?: A
Row 1): The white rook is on another square. On the right Black can stop the passed pawn with 1. … Rh3+ and 2. … Rb3.
Row 2): The white king is on another square. On the left 1. Nc6 Rxf5? 2.Ne7+ saves. On the right this doesn’t wήk because 2. … Rxf5+ is
with check.
Row 3) On the left the bishop is protected. That makes quite a difference. White has time to prevent the mating threat. On the right White loses a piece.
Row 4) The g-pawn is on another square. On the left 1. Bxh7+ wins material. On the right it doesn’t: 1. Bxh7+ Kxh7 2. Rxd8 Bxh3+.

42: Compare / Is the difference decisive?: B
Row 1): The white king is on another square. On the right 1. … Bb4+ wins material.
Row 2): On the right Black has a rook on f8. The defence 2. Nf3 doesn’t wήk now because of 2. … Qxe5.
Row 3) On the right the b7-pawn is on c6 and Black wins the queen. On the left White not only saves himself by 1. Bb5 but he also wins
material.
Row 4) The black king is on another square. On the left White wins a rook with 1. Qxh6.

Βήμα 3 mix

1) 1. … Tf4+ 2. Txd4 Txd4. (discovered check) The X-ray protection of the checking bishop is necessary.After 1. Td2+ White plays his king and after any other discovered check 2. … Txd4 will follow.

2) 1. Dd2 (1. Dd3? Lf4+). (double attack: X-ray attack). 3) 1. Dc3+ Dxc3 stalemate (defending by stalemate)

4) White exploits the material supremacy on the king’s wing. Provoking a weakness and mating. 1. De4 g6 2. De5+.

Pe6 Tf6. Black can easily protect himself against the mating threat.
Pf7+ Txf7 2. Lxf7 Dxc3. a bad idea, even if the check by the knight brings in a gain of material. The knight is a stronger attacker here than the rook.

5) 1. … Td5 2. Txd5 Dxg4+ 3. Kf1 cxd5. Black attacks the pinned rook on f5. White cannot protect the rook and thanks to the in-between move with check Black wins a rook.

6) 1. Pg6+ hxg6 2. Th3# (mate in two by access) 7) 1. … b5 2. Pxd4 bxa4 (trapping)

8) 1. … Pf4 2. Kg1 and Black can choose from: 2. … Txe2 and 2. … Dg5+ which are the most convincing moves. (discovered attack)

9) 1. … Dxc1+ 2. Txc1 Td1+ (elimination of the defence: luring away+mate). The rook on c8 pins Td8 and therefore 1. … Td1+ is not handy at once.

10) 1. Tf8+ (after 1. Txc7 Tc5 2. Tb7 Txe4 can Black play on) 1. … Kg7 2. T8f7+ Kh6 3. Th1+ Kg5 4. Tg1+ (perpetual check)

11) 1. Txg4 (a pinned piece is not a good defender)

12) 1. h4 (1. Lf6? h4 2. Lxh4 Kg2) 1. … Kg4 2. Lf6. It is the only way to keep the last pawn on the board.

1) 1. … Txh3+ (thanks to a pin) 2. Kg1 Txh4 (double attack: rook) 2) 1. … Lg7 (1. … Kg7? 2. Lh6+) (defending against a passed pawn) 3) 1. Dxh7+ Kxh7 2. Th4# (access and double check)

4) 1. c4 d3 2. a5 (square of the pawn)

5) 1. Pb6+ cxb6 2. Da8# (mate in two by access and line clearing) 6) 1. Db7 Dd8. The only move, the rook must keep protecting La7.

7) 1. Td8+ Dxd8 2. Dxe6# (elimination of the defence: luring away+mate)

8) 1. … Df8 (1. … Kh7 2. De4+) (getting out of check – avoiding a double attack)

9) In this game by a young player Black played 1. … Ta8. It is not logical to protect a pawn under attack by an active rook. White’s last move Td4-a4 threatens a winning discovered attack. Only attacking the rook parries the threat and gives some counter-play:

… b5 2. Txa7 b4 and e4 is lost. 1. … a6 2. e5 is winning a piece.
… Tfe8 2. e5 is winning a piece.

10) 1. Pxb3 Dxg4 (1. … Tc4 2. Pd4; 1. … Txb3 2. Dxb4) 2. Lxg4. Gaining a piece thanks to X-ray protection.

11) 1. … Lf4! Wins the knight; otherwise the king will not enter the square of the pawn any longer after 2. … d2 (Van Zuylen van Nyevelt 1792)

12) 1. Th8+ (1. Kb6? Da7+) 1. … Ka7 2. Th7+ Kb8 3. Kb6. Two smart in-between moves prevent the check on a7.

1) 1. Kxc7+ Dxg2 2. Db8# (discovered check) The front piece becomes helper. 2) 1. Dh8+ Kxh8 2. Txf8# (elimination of the defence: luring away+mate)

3) 1. … Lxd4 2. c3 Df6. The counter-attack on the queen saves the pinned piece. 4) 1. g8D+ Kxg8 stalemate (defending by stalemate)

5) 1. Ld5 Txd5 (1. … Lxd5 2. e8D#; 1. … Txb7 2. e8D# (2. Lxb7? Le8) ) 2. b8D+ (cashing in a passed pawn) 6) 1. … g5 (elimination of the defence: chasing away+mate)

7) 1. Lg5 Dg6 2. Lxe7 (double attack: X-ray attack) 8) Can White stop the h-pawn?

Txg6+ wins because after 1. … Kf7 2. Tf6+ the rook comes to f1.After 1. … Kh8 2. Kg5 h1D 3. Th6 White wins the pawn ending easily.After Kxe6 White is already on a key square.
Tg1 without the e-pawns this move would be enough for a draw. Promotion to a queen or rook is stalemate, promotion to a bishop loses all pawns. Black keeps the e-pawn in friendly hands.
Kxg6 h1D can immediately be dismissed.

9) 1. Te1 Txh3+ 2. Te3 (defending against a double attack – X-ray attack)

10) 1. Lf7 makes use of the vulnerable position of the black pieces. Protecting the bishop is not possible (1. … Tc8 2. Le6+)

and capturing on f7 gives White a passed pawn which cannot be stopped.

11) 1. Tc5+! (1. Txa8? stalemate) 2. … bxc5 3. Txa8 (avoiding stalemate) (Tarasiuk 2013)

12) 1. … Tb1 2. Df3 (2. Tf1 Da1) 2. … Da1. Supremacy of the black pieces exploits the vulnerability of the back rank.

1) 1. Dxa3+ (1. Kb2 Pc4+ 2. Ka1 d2; 1. Ka1 Pc2+ 2. Kb1 Pa3+ 3. Dxa3+) 1. … Kxa3 2. Lc5# (mate in two): luring) 2) 1. Ta8+ Kb7 (1. … Kd7 2. Txd2+) 2. Txd8 (X-ray check and X-ray protection)

3) Picture

4) White has a vulnerable pawn on e4 (cannot be protected by another pawn). The pawn is also in the way of the bishop. 1. Pd5 Dc5+ (1. … Pxd5 2. exd5) 2. Kh1 Pg4 3. h3

Pf5 an active move but a single knight cannot do much. Black plays 1. … Dc5+ and 2. … Pe5. The white bishop remains inactive.
Df2 prevents only that Black takes on e4 (1. … Pxe4 2. Lxe4 Dxe4 3. Dxf7+). Black can play 1. … Dc5 or 1. … Tad8. The e-pawn remains weak.

5) 1. … Ld8 2. Dd7 Lb6+ The queen cannot remain protecting b6.Ahidden pin. 6) 1. Pd6# (mate in one thanks to 3x a pinned piece is not a good defender)

7) 1. … Txd2 (1. … Pc4 2. Dc7) 2. Txd2 Df1+ 3. Td1 Df4+ (perpetual check)

8) 1. Pd5 Lf8 2. Pxb6+ (or 2. Ld7+) (elimination of the defence: luring away+mate)

9) 1. … f5 2. Kg2 Pf4+. With the pawn on g3 the move with the knight to f4 is completely out of sight. That explains mistakes like 2. Kg2 (2. exf5 is correct to make the black e-pawn up vulnerable) understandable.

10) 1. … Db7+ (after 1. …. Db1+ the king escapes to h3) 2. Dc6 Dxc6+ 3. Txc6 Txc6 Interposing on c6 is forced and appears a safe move but thanks to the X-ray protection Black wins a whole rook.

11) 1. … Le4+ 2. Kf1 Lxd3+ (discovered check). The back piece is chasing, the front piece is looking for a suitable target. That is not the rook because White is threatening mate on e8.

12) 1. … Pf4+ (1. … Pe3+? 2. Kg1) 2. Kg1 Ph3# (double check). The back piece is pinned so that mate on g2 is not possible.

1) 1. b3 Txh4 2. c7 (cashing in a passed pawn)

2) 1. … Kh8 (1. … Pxe7 2. Pf6+) (getting out of check and avoiding a double attack)

3) 1. … De1+ 2. Lf1 Dxf1+ 3. Kh2 De2+ 4. Kh1 De1+. Draw by perpetual check. White can not allow that the queen can take on e5 with check.

4) 1. … Td2+ 2. Kg3 Lxe3 (chasing away+material) 5) 1. Tb1 Dd2 2. Txb7 (double attack: X-ray attack)

6) 1. … Pxe5 2. dxe5 Dxf3 (capturing+material) or 2. …. Pxe5 Dxh1 (a pinned piece is not a good defender)

7) 1. Ke4 (1. Ld8? f3 2. Lh4 f2 3. Lxf2 Kg5) 1. … Kg5 2. Kf3. The only way to keep the last pawn on the board. 8) 1. Pexg6+ hxg6 2. Pxg6+ Ke8 3. Dh8# (mate in three thanks to pinned piece is not a good defender)

9) 1. Dh5.Activating the queen is correct. The threat 2. Pg6 cannot be stopped without loss of material, otherwise mate: 1… h6 2. Pg6+.

0–0 Not a bad move (developing and king safe) but get used to look for a better move.
Tc1Also a developing move. It is not clear yet which file is the best for the rook. Not moving the rook is obvious then. After Lxc3 White will take with the pawn anyway (improves the centre)

10) 1. … Lc1 2. Pd2 Lxb2

11) 1. … Dg3.Activating the queen: more active is enough.After 2. Df3 Dh4+ 3. Dh3 De1+ wins quickly. 12) 1. Le8 and 2. Pg6# (mate in two)

1) 1. Pb5 Don’t take back without thinking. The move of the knight threatens a fork on c7. Black cannot prevent that.

fxe4 The pawn is a centre pawn and that is fine. It controls squares, it is not being attacked and it clears square f3. The move is the best if a move of the knight to b5 (or d5) would not be possible.
Pxe4. Knight in the centre but it can be easily chased away by f5.

2) 1. … Txe6 (defending against mate thanks to pinned piece is not a good defender). The threat was Tf7#. 3) 1. Dh4+ Ke5 2. Dxd8 (X-ray check)

4) 1. … Pxd4 2. Db2 Pxf5 (double attack: knight, thanks to a pinned piece is not a good defender) 5) 1. … Kd8 (1. … Kf8? 2. Pd7+) (getting out of check and avoiding a knight fork)

6) 1. Dc4 a5 2. Dxc6+ bxc6 3. La6# (mate by access).Aknown mating pattern with two bishops. 7) 1. Ke7 (helping the passed pawn and holding off the enemy king ) (Averbakh 1954)

8) 1. … Pg4+ 2. hxg4 Dh6# (mate in two by access)

9) 1. Dc7 (elimination of the defence: luring away+mate). The threats 2. Dxe8 and 2. Dxe7 are not to be parried.

10) 1. Ke3 (1. Lxb5? Kd4 2. Lc6 b5 3. Lxb5 Kc3). Holding off the enemy king first is the only way to preserve the last pawn on the board.

11) 1. Lf3 (an oversight is 1. Lg6 hxg6+ 2. Kxg6 Le4+) 1. … Lxf3 stalemate (Velijkhanov 1990) 12) 1. Dh4+ (1. Dxa2 Lxf3) 1. … Dxh4 2. g4+. White lures the black queen away and mates.

1) 1. Td1 (trapping)

2) 1. … Kb7 (1. … Lxa5 2. Pd6). Black traps the knight. White cannot capture the bishop, the king must remain inside the square of the c-pawn.

3) 1. … Lxc3 2. Dg4+ Kh8. Black thought to win a piece with capturing on c3. What a waste of the nice bishop, 1. … Dxa4 would be better. Recognizing your mistake in time and trying to save the piece: 2. … Lg7 3. Lh6 is mating.

4) 1. Tbb5! (1. Tba4 Pg3). (the pin: attacking a pinned piece thanks to a pinned piece is not a good defender) (Stavrietsky 2009)

5) 1. … Pf4+ (1. … Pe3+? 2. Lg3 Pxd1 3. Taxd1) 2. Kh1 Dg2# (discovered check). Do not fire the front piece directly at the queen. First have a look if there is something better.

6) 1. e6! (to play for a win loses 1. Kf5 Kf3 2. Kf6 Kf4) 1. … fxe6 stalemate (Zinar 1984) 7) 1. Th5+ gxh5 2. Dg7# (mate in two by access)

8) How does Black protect his b-pawn?

… b5. Normally it is not recommended because Black gets two weak pawns (a6 and c6). Here the move with the pawn is fantastic because the white rook can play no more moves.
… 0–0–0. Developing and protecting seems logical and castling is also not bad, but by far not the best. 1. … Ta7. Not only an ugly move, but also it costs a pawn after 2. Lb8 and 3. Txb7.

9) 1. Dd4+ Kg8 2. Kf1 (defending against mate by preparing interposing)

10) 1. Pf5 Dd8 (1. … De5 2. Lf4) 2. Pxd6. The queen can no longer protect d6. Chasing away+material because Black may not capture the knight.

11) 1. … Pe5 (double attack: knight, thanks to a pinned piece is not a good defender)

12) 1. Tfe2 Kg6 2. T2e6+ Df6 3. Txf6+ (exploiting vulnerability: the king has little mobility and the queen is in such cases a worthless defender).

1) 1. Df4+ Kd5 2. Dc4# (mate in two: chasing)

2) 1. … Td8 2. Dc4 Dxd4 3. Dxd4 Txd4 (double attack: X-ray attack). First taking with the queen because Lc8 must remain protected.

3) 1. a7! (1. Kg6? Kc6) 1. … Lxa7 2. f6! (2. Kg6? Ld4). Draw by exchanging the last pawn. 4) 1. Dg6+ Tg7 2. Dxf6 (elimination of the defence: luring away+material)

5) 1. … Dxe2+! 2. Lxe2 Kxb7. Draw by eliminating the last pawn.

6) 1. … e5. First protecting the d-pawn and only after 2. Pf3 play 2. … De7. 1. … De7. The move played pins the c-pawn but White can capture on d4.

… bxc5.Also not logical.After 2. Dxc5 Black cannot protect the d-pawn in a proper way. 7) 1. Pxf6+ Dxf6 2. Dxf6 (discovered attack). Suddenly the g-pawn is pinned.

8) 1. Ke6 (1. La2? Kd4 2. Lb1 d5) 1. … cxd5 2. exd5 Kb6 3. Kxd6. Transposing to a won pawn ending. 9) 1. … Df4+ 2. g3 Tc2+. Exploiting vulnerability: by a material supremacy and lack of defenders.

10) 1. Dh5+ Kg8 2. Txd4. (in-between move and a pinned is not a good defender)

11) 1. … Kh7 (1. … Txf8 2. Dh6+) 2. Dh4+ Lh6+ (getting out of check and preventing the threat Dh6+ ) 12) 1. Tf5 (1. Kc4? Txc2#) 1. … Lxf5+ 2. Kc4 (defending against mate by making a flight square)

1) 1. Pf4 Ke1 2. Pd3+ Ke2 3. Pxf2. Eliminating the pawn. 2) 1. Ld6 Txb7 2. axb7 (creating a passed pawn)

3) The bishop is hanging. How does Black defend? Be always aware of the possibilities of the opponent: the existing ones and the new ones after the move played!

… Db7. The queen protects both bishops from b7 and prevents Pxd5. The correct move. 1. … Lf6. Keep an existing threat in mind: Pxd5.
… Dc7 2. Pxd5 is now possible because the bishop on a6 is no longer protected.

4) 1. … Kf4 (1. … Kf3 2. Kg7 Kg3 3. Kxh6 Kxh3) 2. Kg7 Kg5.Aking can always choose different routes. Sometimes it makes no difference, often it does.

5) 1. … Dxg5 (1. … Dxe1+ 2. Kh2) 2. Dxg5 Lc2 (defending against mate). Black has enough material for the queen. Giving material is always better than being mated.

6) 1. Lh6+ Dg7 (1. … Lg7 2. Dh8#) 2. Dh8# (mate in two by luring a defender into a pin) 7) 1. Lxa7 c5. Pawn a7 was poisoned. The bishop will be lost.

6) 1. g4 Tac7 (1. … Ld7 2. Pxd7+). The counter-attack is the only defence.

7) 1. h3. Making an escape square is handy if there are no urgent matters.After 1. … Le6 2. Dxa7 Black is thanks to his more active pieces somewhat better.

Te1. Prevents a possible mate on the back rank too but Black now can play for exchanging queens with 1. … Dd2 (that costs no move to protect a7). White doesn’t win his pawn back.
Pc4. Too active.After 1. … Dd1+ 2. De1 Dxe1+ 3. Txe1 Le6 White remains just a pawn down. The black rook can quickly enter on d2.

8) 1. Lh7 (defending against mate)

9) 1. exd5 e4 2. Kc4 exf3 3. Kd3. Not every breakthrough works. The white king is in the square of the pawn. 10) 1. Tf7+ Kxf7 2. De7# (mate in two by clearing a square)

11) 1. Pf7+ Kg8 2. Ph6+ (perpetual check). The mating threat on h1 prevents 2. Pxd6. 12) 1. g4 Df3 2. Pf8+ (threatening mate, bringing in the guard )

3) 1. … h4 (elimination of the defence: luring away+mate)

4) White can take back in three ways on d4. Thinking is required.

cxd4. White improves his pawn structure. That Black can exchange the bishop on d3 with 1. …. Pb4 is a pity. The advantages of a strong centre are more important.
Lxd4. Nothing wrong. The bishop is active and Pxd4 would improve the white pawn structure. With 1. … De7 followed by Pe5 Black keeps a firm control over e5.
Pxd4. The worst choice. Black wins at least a pawn with 1. …. Pg4.

10) 1. … Pd1 2. Df1 (2. h4 Pxf2) 2. … Dxd2 (chasing away+material). The queen cannot keep protecting the knight and the rook.

11) 1. Dc3 Exploiting vulnerability.After 1. … Pg7 2. Dg7 decides.

12) 1. Tdd7 Dxd7 2. Txg8#. Exploiting vulnerability. Black has too few defenders.

1) 1. … Le5 2. Dh4 Lxb2 (double attack: X-ray attack)

2) 1. Kg5 (1. Kh7 Th6#; 1. Kxf5 Tf6+) (getting out of check; mate and avoiding an X-ray check) 3) 1. Pf3 (elimination of the defender followed by a knight fork).AStep 4 subject but a simple one.

4) 1. Kg1. First defending, only the advance the c-pawn (1. … Kh2 is a threat). Because of his g4-pawn the black king cannot step into in the square of the pawn.

5) 1. Tb1. Logical, White must activate his rook.After 1. … b6 2. La6 Td8 he can try to enter with the rook with 3. a5. 1. Le2. The bishop does not perform much more on e2 than on f1. Black has time to protect pawn b7.

h4. Threatens nothing. Black plays Ta8-d8-d7 as well. 6) 1. Dxg7+ Kxg7 2. Pxf5# (double check by access)

7) 1. … Tc3! 2. Txc3 (2. Td1 Kxf3). Capturing directly on f3 is a mistake: 1. … Kxf3 2. Pd2+ or 1. … Txf3 2. Tc4#. Draw by stalemate or insufficient material (Aloni 1996)

8) 1. Pxd5 De8+ 2. Pe3. The check by the queen unpins Pf6.After interposing Pd5 on e3 the knight is safe. 9) 1. … Ke8 (1. … Tbb7 2. Dg8#) (defending against mate)

11) 1. … Pe8 with a winning pin. To deal with the threat Dxf6+ by 1. … Kg7 is too easy-going. Look always if there is no better move.

12) 1. Da4 (attacks the knight a third time) 1. … Pe7 2. Txc8+ and 3. Lc6. Difficult, but the pin to the king on e8 is a well-known pattern (or should be!).

1) 1. Tf3 Dxe2 2. Pxe2 (trapping)

2) 1. Tf2 parries the threat Te2. The move with the rook is the best. It is sometimes better not to exchange. 1. Tfe1 costs the a-pawn after 1. … Txe1 2. Txe1 Dxa4.

Kh1 Te2.Allowing a rook on the second rank is not wise. White will quickly lose material. 3) 1. … Lc6 2. Txg7 Th1# Exploiting vulnerability: threatening mate.

6) 1. … Tb4 2. Dxd2 Txb1+ (discovered attack and in-between move)

7) 1. Dxf7 De3+ (1. … Dc6 is not necessary). Don’t look for the threat of the opponent alone.

8) 1. Txf6+ (1. Ta8? Te8+ 2. Txe8; 1. Kh8 Th7+ 2. Txh7) 1. … Kxf6 2. Th6#. Mate in the endgame is quite common. 9) 1. b4+! (1. Ka2 Kb6 2. Kb2 Kc6 3. Kc3 Kd5 4. Kd3 b4) 1. … cxb4+ 2. Kb3.Acommon action.

8) 1. … Lc7+ 2. Kh3 f1D+ 3. Kh4 Df2+ (defending against mate by counter-attack)

9) 1. Pf2. Moving the knight to a better square is correct. Black must get no time to play Df8 and Tf6: 1. … Df7 2. Pg4 Tf6 3. Pxf6

Thg1 and 1. Dg2 see previous comment. Decent moves but not the way to make progress quickly.

10) 1. Dxh7+ Kxh7 2. Lf1 (White cannot let the king escape after 2. Th3+ Kg7). Now mate is not to be prevented.

11) 1. … Le4 (double attack: 2 pieces). The target is a twofold attack (Pf5) and an advantageous exchange (a less common one; two captures from both sides).

12) 1. Txa7+ Kg6 2. Ta1 (defending against mate thanks to an in-between move and X-ray protection).After playing 1. Ta1 at once, Black exchanges and wins with 2. … a5. The black bishop can quickly take the c- and d-pawn.

1) 1. … f5 2. Pf6+ (2. exf6 Txe4; 2. Te2 fxg4) 2. … Txf6 (double attack: pawn, thanks to a pinned piece is not a good defender)

6) 1. Th1 Dxh1 (1. … Txd1+ 2. Dxd1) 2. Dxh1 (defending by X-ray protection) 7) 1. Pb5. Fine move. Black cannot protect d6 adequately due to the pin of Pe7.

Lb5.Adeveloping move without power. The pin of Pd7 is harmless. Directly 1. … a6 (forces to move the bishop) or 1. … cxd4 are good reactions.
dxc5. Black captures the centre pawn on e5.

8) 1. … Txf1+ (1. … Tc2+ 2. De3+) 2. Kxf1 Dxc1+ (double check and elimination of the defence: capturing+material) 9) 1. Tg2+ (1. Txh6? Tb7+ 2. Kf8 Kxh6) 1. … Kh5 2. Th2+ Kg5 3. Tg2+ (perpetual check).

5) 1. dxc5. It is not always a good idea because Black can take back with a developing move. Now it is good because that move fails to the fork 2. b4.

Le2.Adeveloping move after which 1. … c4 can follow. Suddenly the knight on a5 is not situated badly any longer (it can go to b3).
Lb5+ gives Black the opportunity to retreat the a5-knight.

6) 1. Txf7+ Pxf7 2. Txf7+.Again of material by a threefold attack on f7 and a twofold one on a7. 7) 1. Td8+ Lxd8 2. Dxf7# (mate in two by access)

8) 1. Th6+ Kg7 2. f8D+ Kxf8 3. Th8#. Giving up your passed pawn is not always the first move you look at. 9) 1. Dh5 h6 2. Dxc5 (double attack with two pieces)

3) 1. … f5.Agood way to get rid of the double f-pawn.After 2. Lxc6 bxc6 Black gets a double c-pawn but that one doesn’t harm at all. There are sufficient defenders around the black king and no attackers.

… De8. Not bad but why putting the queen in a less active position?
… Dxg4. White can activate his knight for free (2. Nxg4) and f6 cannot be protected (2. … f5 3. exf5 Lxf5? 4. Ph6). 4) 1. Lb5+. Black loses material because his pieces are clumsy situated.

5) 1. Dh5 (1. Lxf6 gxf6) 1. … h6 2. Lxf6.Activating the queen and Black has too few defenders. 6) 1. De2 Le6 (trapping by lifting the pin and depriving the bishop of square c4)

3) 1. Ld5 (1. Tc3 Tc8) 1. … Ta1+ 2. Kb2 (defending against a double attack by counter-attack) 4) 1. … 0–0. Good move, bringing the king into safety.

… Lxe5 2. dxe5. Black is a pawn down and has compensation (says opening theory). Exchanging queens then is not wise. 1. … De7 (the move played costs a piece after 2. Da4+). White missed the double attack.Also in the remaining part of the game Step 2 combinations were missed and allowed by both sides. This can happen, on the other hand it is unwise in these cases to teach children, who drop pieces over and over again, 12 moves of opening theory. That time can be spend better.

De7. The queen can become more active without danger. Black cannot protect f7 a third time. 1. Tad1. Healthy developing move, nothing wrong with that. Only, there was a better one.
Da3. No reason to retreat the queen. 10) 1. a8L b2 2. Le4 (avoiding stalemate)

9) White is winning and all moves are good enough to retain the advantage or expand it.

g5 fxg5 2. De5. Opening the long diagonal directly is the fastest. It doesn’t make any difference that White cannot take back on g5 . The queen must be activated. (Chernin-Santacruz, Mendoza 1985)
h4. White doesn’t need to prepare for g5 and h5 is not the best plan because Black plays g5 and keeps the position closed. 1. Ld5. Not a bad move but after 1. … g5 White has to do some work: move away the queen and prepare f4.

10) 1. … Tf7 2. Txd8 Dxd8+ (the pin: attacking a pinned piece thanks to a pinned piece is not a good defender) 11) 1. … Pe3 2. Dd3 Txd3 3. cxd3 Dd6 (double attack with two pieces; X-ray protection)

12) 1. Kd6 (1. c5? Kc4 2. Kd6 Kb5) 1. … Le8 2. c5 Kc4 3. c6 White must prevent that the black king helps defending.

3) 1. … d3+ (1. … dxc3+ 2. Lf2 cxb2 3. Pc3 La5 4. Pb1) 2. Kf1 d2 (discovered check). Two possibilities, always compare. Not an immediate capture.

4) 1. Pf8 De5 (1. … Dxf8 2. Ta8+) 2. Ta8+ The move with the knight protects g6 and threatens mate. Wonderful.

5) 1. … b6.Agood developing move. It is useful if c5 is well protected in case the c-file will be opened. Furthermore the move of the pawn makes room for the bishop. On the long diagonal it will be more active.

… a6. Not really necessary. Finishing the development is wiser. 1. … dxc4. Unhappy choice because of 2. Lxh7+.

9) 1. … Pf6 (1. … Txd2 2. De8+ Kh7 3. Dg6+). Starting with preventing perpetual check, the bishop will not run.

10) 1. Dg6 Tf8 2. Dxh5 Kh8 3. Lxf7 Kh7 4. Lxh6 gxh6 5. Dg6+ (double attack: queen, thanks to a pinned piece is not a good defender)

Ld6. Preventing castling is a fine idea. It is a pity that White has no more active pieces nearby. Black can just play 1. … Lf8 play and after exchanging the king will go to g7.Also 1. … dxc4 is possible. White cannot take back directly (2. Lxc4 Pb6).

Acheck on a1 is a move that feels illogical. Keeping the possibilities in the position is appropriate here. The check can wait. You must choose a move that feels good without the necessity that you can calculate everything.

… Pg6. Played with the correct assumption that the black knight is better than the white one. The knight can become active via h4. Luckily, that after 2. Pe4 Black has a forced win with 1. … Ta1+ 3. Kd2 Td8+ 4. Ke2 Pf4+.

7) 1. … Tg2+ 2. Kxg2 Le4# (luring and double check)

8) All attention goes to the attack on the bishop. It is three times attacked and protected only once. Moving away seems the only possibility. If we look for vulnerability then the weakness of Black’s back rank strikes.

Tf1. This move is indicated so a good reason for a closer look. It turns out that Black has only one move: 1. … Kg8. Now 2. Dd5+ is logical and forces 2. … Kh8. In a game you can execute the move with the rook. The white pieces are so much better. Even that good that there are many good continuations. If this position is on the board they are easy to find: De5, Tf7, Dg5 are the strongest.
Lh3. White keeps the more active position but with 1. …. De8 Black can make the back rank less vulnerable. 1. La4. Black can now capture on b4. Scary but 2. Td8 is harmless because 2. … Dc5+ and 3. … Tc8.

9) 1. Td7+ Ke8 2. Td5+ Ke7 3. Td7+ (perpetual check thanks to a discovered check and interposing) 10) 1. Lxh7+ Kh8 2. Le4+ Dxh1+ 3. Lxh1 (chasing and discovered check)

11) 1. Lb5 Da5 2. Lxc6 (double attack: bishop, and a pinned piece is not a good defender) 12) 1. … Db5+ 2. Kg1 Da6 (defending against a passed pawn)

1) 1. … Dxh3 2. gxh3 g2# (mate by access)

2) 1. … dxc4+ 2. Lxc4 Pxc4 (elimination of the defence by capturing and a pinned piece is not a good defender) 3) 1. g3 (discovered attack and trapping)

4) 1. … Dxc5 2. Dg5 (lifting the pin by counter-attack)

5) 1. Tc1 (1. Lf3? h1D) 1. … Kxh1 2. Kf2# (mate in two)

6) 1. … Pb4. The best move. There is no adequate defence against a check on c2 and d3.

… La3. Developing a piece to an active square is a good move, but not the best. White fights on with 2. Td1.
… Lb4.Active but White can chase the bishop back with 2. a3. Due to the possibility of Pb4 the move of the pawn is useful.

7) 1. Dc5 Ta8 2. Dxd5 (double attack: queen)

8) 1. Dg1 (1. Kh2 De5+ ) 1. … Tf1? 2. Td8+ Kh7 3. Txg7# (getting out of check and preventing a real threat).

9) 1. Kd3 (1. h4 c4 2. h5 c3+ 3. Ke2 c2 4. h6 c1D) 1. … Kb3 2. Kd2 Kb2 3. Kd3 active defence by threat (conquering the pawn and coming in front of the pawn)

11) 1. Txf4 (1. Ke2 Tc2+) 1. … Lxd3 (1. … Kc5 2. Tf8) 2. Txd4+ (defending) 12) 1. … Pe5 2. Dxe5 Lxe5 (discovered attack and trapping)

1) 1. Tg4 Dxb2 (1. … Ld7 2. Dc5+ Kg8 3. Txg7+) 2. Dc5+ (elimination of the defence: chasing away+mate)

2) 1. Pb5 Lxb5 (1. … Dd8 2. Lxc6; 1. … Dc8 2. Pd6+) 2. Lxa8 (chasing away+material and a pinned piece is not a good defender)

3) 1. Td8+ Txd8 (1. … Kh7 2. Dxc3 Txc3 3. Txa8) 2. Dxc3 (elimination of the defence: luring away+material) 4) 1. Ld4. Only active square left for the bishop. Black must do something against the threat 2. f4 (i.e.. 1. … Lf6).

Lxb4 opens the long diagonal so that a discovered attack is possible: 1. … Pf3+
Lxe5.Afirst Step move, capture whatever you can capture without losing points. That phase lies in the past.Awaste of the good bishop.

5) 1. Txe5+ fxe5 2. De7# (double attack: rook and a pinned piece is not a good defender)

6) 1. fxe5 f5 2. Txf5 Pxf5 (elimination of the defence: chasing away and luring away+ mate) 7) 1. Tc2 Txc2 2. Lxc2+ (elimination of the defence: capturing+material and in-between move) 8) 1. … Dxd4+ 2. Lxd4 Lxd4# (mate in two thanks to X-ray protection)

9) 1. Pf5 exf5 (1. … Da3 2. Lc1 Da7 3. Pxe7+) 2. Lxc5 (discovered attack and elimination of the defence) 10) 1. … Df8 (1. … e4? 2. Pxe4) (double attack: X-ray attack)

11) 1. Lf4 Lxd3 2. Lxh6+ (chasing away+material and in-between move) 12) 1. … Pc6 2. Da8 De5# (double attack with two pieces)

1) 1. Lxd5+ (a pinned piece is not a good defender) 2) Taking into account the possibilities of the opponent.

… Lxf3. It is a pity for the bishop but a good possibility.
… Dd7 2. Pxe5 Pxe5 3. Dxe5 is also possible if you dare to sacrifice a pawn (3. … Ld6 4. Dc3). White has enough play for the pawn.
… f5 (the move you would like to play) fails to 2. Dc4+

3) 1. Pxd4 cxd4 2. Te1 Dxh3+. Black profits from the pinned g-pawn. The move with the knight opens the diagonal of Lb7 and the move of the rook gives up the protection van h3.

4) 1. Lb2 Ke5 2. c4# (mate in two)

5) 1. Le5+ Ke7 2. Ld6# (double check and luring)

6) 1. … Df5 (defending against a pin; eliminating the attacker) 7) 1. … Lc7 2. Dd4 Dxc1 (activating the bishop)

8) 1. Dh4 Dxd3 2. Tg8# (bringing in the guard)

9) 1. … Df3 2. Tc2 Ld5 (activating the queen, the bishop must follow)

10) 1. … Ke7. With a rook up Black can play for a win.After 2. Te1 the king must go to f6 and that looks scary but it is not. White has only two attackers and Black has sufficient defenders.

… Kc8 (repeating the position after check on a8 and d5; the king must go to e7) 1. … Ke8.Amistake, after 2. Te1+ the king must abandon the protection.

11) 1. … e3+ (1. … f1D 2. Tf8+; 1. … f1P+ 2. Ke1) 2. Txe3 f1D (cashing in a passed pawn)

12) 1. … Tf4 (1. … Tc3? 2. Dxf7+) 2. gxf4 Dxf3 (elimination of the defence: luring away+mate and a pinned piece is not a good defender)

1) 1. … Tdg7 (defending against loss of material and mate) 2) 1. dxc4

bxc4. The move is played with the thought: ‘I don’t want to lose the right to castle’(this will be the case after exchanging queens). Moving and not looking any further. Unfortunately 1. … Dd4.

Pf3.Apawn sacrifice without activity in return. Black can capture on d3 or play e4. 3) 1. Td4 Txf7 (1. … Lxd4 2. Dxd4+) 2. Txd5 (the pin: pin)

4) 1. … Kg8 (1. … Kxg6; 1. … Kh6 2. g7 Kxg7) 2. g7 Pb5 3. Kxa2 Kxg7 (avoiding stalemate) 5) 1. … Db7+ (double attack: X-ray check)

6) 1. Ph4 Txf1 2. Dxh5 T8f2#. The move of the knight was not a happy one. (Merciai-Starr, Haifa 1976) 7) 1. Pd1 (discovered attack and trapping)

11) 1. Pf4+ (1. Pxe5+ Kf8) 1. … Kf8 (1. … Kf6 2. Lh4#) 2. Pe6# (chasing, taking away an escape square and discovered check)

12) 1. Pg5 Txe1 2. Txe1 Pe4 3. Pxf7 (gain of material thanks to in-between move)

1) 1. Df6 (1. Txd5? exd5 2. Df6 De1+ 3. Kc2 De4+) 1. … Pxf6 2. Td8+ (a pinned piece is not a good defender) 2) 1. Tf3. Increasing the pressure on f6 is fine (both pinned pieces are no good defenders).

Tce3. Threatening something (i.e.. capturing on f7 and Te8+ or at once Te8) is not enough in case there is a simple defence is: 1. … Ld7 2. Te7 Pd5 3. Ld3 Pf6. It is too late for 2. Tf3 because of 2. … Te8.
Lxf7+. Lifting the pin removes the pressure, try always to maintain the pressure (except for an immediate win!) 1. … Dxf7 and nothing has been achieved.

3) 1. … Dg4 2. Lxd5? Lb4+ (defending by counter-attack)

5) 1. … d5. Excellent. White must more or less play 2. exd5 exd4 3. d4.After exchanging on d4 and c6, White’s two minor pieces are passive.

… Ph5. Logical, but 2. Pe2 prevents the move of the knight to f4 and prepares an action in the centre with d4 at the same time.

Βήμα 4 mix

1) 1. Dxg7+ Txg7 2. Pf7+ Txf7 3. Tg8#. White opens the g-file by luring the rook to g7. The rook on g7 has a double function: protecting the square f7 and keeping the g-file closed. Luring the rook away leads to mate.

2) 1. … d1=D+ (1. … Lg4+ 2. Kxd2) 2. Txd1 Lg4+. The d-pawn hangs and the black bishop cannot (yet) interfere because of the rook on g1. Sacrificing the passed pawn first is the correct solution.Astandard action.

3) 1. f7 Dxf7 (1. … Lxf7 2. Dh6+ Kg8 3. Dh8#) 2. Dh6+ Kg8 3. Dh8#. If the queen checks on the first move, then the black king escapes via g8 to f7. Blocking is the suitable way to take away the escape squares.

4) 1. … Txd4 2. Txd4 Dxd1+. The capturing on d4 makes an X-ray attack on the d-file possible. Beware: Black only wins because of mate on the back rank. With the white pawn on h3 costs the action would just lose material.

5) 1. Lg5 Df8 2. Lxd8. The black queen must protect f7, so giving up an exchange is the lesser evil. 6) 1. Lf3. The bishop protects pawn e4 and the threat 1. … Dxc3 is prevented.

Tfb1. The queen has not been trapped: 1. … Dc2 or 1. … Pxe2+ is adequate. The best is 1. … Dxc3 2. Dxc3 Pxe2+. 1. Ta2 Pxe2+. The refutation: the queen must protect Pc3 and the knight must protect Ta2.

7) 1. Kf1 (White must prevent that Black can take on e5 with check: 1. Kh1? De1+ 2. Kh2 Dxe5+) 1. … Df4+ 2. Lf3. The only move but adequate: 2. Kg1 Dd4+. Defending is sometimes necessary.

8) 1. … Te2 2. Dxf4 Lxb2# (2. … Tc2+? 3. Kb1 Txb2+ 4. Kc1).Across pin.

9) 1. … g5. Makes an escape square (h5) for the king. The threat was Ph2#. Now after 2. hxg6 hxg6 the square h2 is protected by the rook. Black is enough material up.

10) 1. f5! gxf5 (1. … g5 2. f6 La7 3. f7 Lc5 4. Ke6 Kxf2 5. Kf5) 2. f4! Lxf4 3. Ke6 Le3 4. Kxf5. Technique: eliminating the last pawn.

11) 1. De2 Pd4 with the idea to open files (Black always gets his piece back 2. cxd4 exd4).All pieces gain in activity. Unfortunatel , but 2. Lxd4 spoils the fun (but only because Te8 is insufficiently protected). With the king on f8 Pd4 is a fine move.

12) The threat is Txg6+ with a win. The bishop can be protected only in one way: 1. … Dg7 (unpins more or less the bishop too) 2. Dh4 (or 2. Dg5 Df8) 2. … Df8. The problem has been solved correctly. The move with the queen is relatively easy to find, all other moves lose instantly. We will see if White can still achieve something: 3. f4 (3. Dh5 Dg7 is a repetition) 3. … d5 (eliminating an attacker by interposing) 4. f5 (or 4. Lxd5 Td8) 4. … Td8. The pawn’s move to d5 is the best move (or first 3. … Td8) but the black position is good enough (important to sense that) so that also other moves are adequate:

… exf4 forces White to make a draw with 4. Dh5.
… Tb8 shows another way of defending: eliminate an attacker. 4. f5 Txb3.

1) 1. … Tf4+ 2. Kxf4 Dg4#. With (too) few attackers blocking and the magnet are excellent weapons. The second makes mate in two possible. 1. … d5+ 2. cxd5 Tf4+ 3. Ke5 is only a draw by perpetual check.

2) 1. Lxf7+ Kxf7 2. Pg5+ Dxg5. It is possible because the white queen hangs too. Such a mistake is more or less forbidden at Step 4 level.

3) 1. … Lf3 2. De1 Dh3.Agood technique. Black makes the defending move f3 impossible.

4) White wants to play d7 without allowing Ke7. With a check a knight can quickly offer a helping hand in the defence. 1. Kf6 (now a saving check is not possible. Wrong is: 1. Ke6? Pe2 2. d7 Pd4+ 3. Kd6 Pb5+) 1. … Pe2 2. d7 Pd4 3. d8D#.

5) The threat is: capturing on h2 and mate. Tg1 must keep protecting g2. Nothing better than protecting h2: 1. Pf1 (1. Df1 Dxh2+ 2. Kxh2 Th4+).

6) 1. … Tb7 2. Dxb7 Pc3+ (luring and discovered attack)

7) 1. … Dc6+ 2. Kh3 Dxd7+ 3. Dxd7 b2. (cashing in a passed pawn by eliminating the possible defences – mate on g7 and Tb7 after a move like 1. … Dg5.

8) Only the white rooks are not on the best squares yet.All other white pieces are active. White must hurry because Black has two centre pawns and with d5 he can control square e4 and make the bishop on f3 less active.

Pde4 is the correct choice.Aquick mate with 2. Pxf6+ threatens and 1. … Pxe4 2. Dxe4 White gives a winning double attack.
Tad1. Not every developing move is good.After 1. … d5 it is wise to play 2. Pde4 and exchange a bit, otherwise the knight on d2 will be passive.
Pge4. Not bad but less good than the other move with the knight. Black plays 1. … Pd5 and gains some time: 2. Lg3 La6.

9) 1. … Pxf6 2. Txf6 Dxf6. The pin: a pinned piece (Lg7) is not a good defender.

10) 1. … Th5+ 2. Kg1 Lc5+ 3. Kf1 Th1# (chasing and double check) Gaining a piece with 1. … Txe2 wins too, even if White couldn’t play 2. Kh3.

11) 1. b8P+ Kd6 (1. … Kc5 2. Pa6+) 2. Dg3+ Chasing and X-ray check.

12) 1. Pd4 De1 (1. … Lxd4 2. Dxe2) 2. Dd8#.Adouble attack with two pieces. The knight attacks the queen and the queen threatens mate on d8. The pin over the e-file is essential; move Pc4 to f4 and White has nothing.

1) 1. … Lxg2+ 2. Kxg2 (2. Kg1 Lc5+ 3. Ld4 Lxh3) 2. … gxf6+. Counter-attack is the only defence against the white mating threat.

2) White’s supremacy is obvious. Black has some defenders. White can win in more ways. For the first win help of the double attack is necessary and is for Step 4 the appropriate way: 1. Tg6 Dxf5 (after 1. … Txg6 the pawn fork decides 2. fxg6+) 2. Tg7+ Kh8 3. Tg8+ Kh7 4. Th8+ or 4. Dg7+). The second way is 1. Tb8 (1. Tc8 is in most cases about the same; it is silly to play 1. Te8 because e7 is protected two times). How must White win after 1. … Tg7, 1. … Dg7 and 1. … Tf8 is difficult. It is difficult but can be done by 2. Txb7, luring the defending rook away and White wins. Black can persist with 1. … Tf8 and a lot of good moves are required: 2. Txb7+ Kh8 3. Tg7 Dd8 4. Dd2!

3) 1. Pxf6+ Lxf6 2. Txe5.Awinning discovered attack because the bishop will be pinned.

4) The is unlikely that the g-pawn can cause any danger. That is true, after 1. g6 Kh6 2. g7 Dc3 White’s fate is decided. Making a draw is the highest achievable. Happily White can give away his pieces in a smart way: 1. Lg6+ Kxg6 2. Pe5+ dxe5 stalemate (Blumenbach 1909)

5) 1. Txd3 Dxd3 2. Dxd3 Tc1+ 3. Df1Awin for White.

6) Take always the possibilities of the opponent into account if you are getting out of check.

g3. This move with the pawn is the best. The threat 2. Tc8+ forces 1. … Te8 and after 2. Tc7 White wins a pawn anyway and his major pieces remain active.
Tc7.Allowing a pin voluntarily is hardly ever wise and certainly not here: 1. … Tc6.
Dc7 seems very strong but is not more than just a decent move.After 1. … Dxc7 2. Txc7 h6 3. Txb7 the move would be indeed strong. However Black plays 1. … Te8 (capturing is not mandatory and no pawn is lost – though the endgame remains difficult for Black).

7) What is the difference between the two king moves? Black must be prepared for an action by the rook via a4. For this reason square h7 must remain empty. 1. … Kh8 (1. … Kh7 2. Ta4 Te1+ 3. Dxe1 Dxc2 4. Tg4) 2. Ta4 Dxc2 3. Th4+ Dh7. The two remaining rooks are strong enough to achieve a draw.

8) 1. … f3+ 2. Dxf3 (luring the front piece and pin) or 2. Kxf3 Ld5+ (chasing away+material) or 2. … Lxg4+ (luring away+material).

9) Two bishops are enough to mate, one is not: 1. Kf2 Lh3 2. Kg3 Lg4 3. e4+ Kxe4 4. Kxg4.

10) 1. … Pxf4 2. Dxf4 Lg5 3. Dg3 Lxc1. Luring and X-ray attack. (elimination of the defence by blocking) (Kaljagin 1989) 11) 1. Te5+! Dxe5 2. Dg6#. Mate in two thanks to blocking.

12) 1. … Dc5 Why to c5 and not to b6?After 2. …. Db6 3. Db4 White protects the bishop with tempo. Due to the threat 4. Dxf8+ and mate Black has no time to capture on d4. 2. Td1 Lxd4 3. Dxd4 Dxb5 (elimination of the defence by capturing)

1) 1. Pf5+ exf5 2. Pd5+ (luring away and double attack: knight) 2) Drawing

3) 1. Pf6+ gxf6 2. Dxf6 (attacking the king: access)

4) 1. … Df1+ 2. Txf1 Pe2# (elimination of the defence by blocking) (Najer-Nepomniachtchi, Moscow 2006)

5) 1. … Pxf3+ (1. … Dxd4+? 2. Dxd4) 2. Kf2 Dxd4+ (2. … Pxd4? 3. Pxc5) (a pinned piece is not a good defender) 6) 1. … Db8+ 2. Kg2 (2. Dg3 Th1+ 3. Kg2 (3. Kxh1 Dxg3) 3. … Tg1+ 4. Kxg1 Dxg3+) 2. … Dg8+ 3. Dg4 Dxa2+

7) f6 Tg8 2. Dg7+ Txg7 3. hxg7+ Kg8 4. Pe7# (attacking the king) 8) 1. … Tc1+ 2. Kh2 Dxd6 (defending against a pin)

9) 1. f5. It is logical to destroy the pawn structure. The knight cannot move because of 2. Pf4.

Tae1.Ahealthy developing move but Black plays 1. … Pcd4. Now White must proceed too with f5. It is better to play the move at once.
Tad1. White must make progress by playing f5. It is better to play the move at once. 10) 1. … Lg6 (1. … Lxf3 2. Ta8+ Kh7 3. Ld3+) (defending by moving away)

Kh2 f4 8. Tgb3 f3). So far the white moves are simple. The question is whether Black can stop the b-pawn permanently: 3. … Kf6 4. b5 Ke7 5. b6 Kd7 6. b7 Kc7 7. Tb2 (helping) 7. Kb8 8. Txg6 (forces the queen back) 8. Dd8 9. Ta6 (helping) 9. …. Dd5+ and now only avoiding a check: 10. Kh2.Along line but all white moves are not difficult to find by elimination (cashing in a passed pawn)

3) 1. Lf6 (attacking the king: exchanging the defender)

4) 1. … Td8 2. Txd8+ Dxd8 (defending against elimination of the defence) 5) 1. … Dxf4+ 2. Txf4 Le3+ 3. Kb1 Txd1# (mate in three)

6) 1. Tf3 Td5 2. Tc8 (cashing in a passed pawn) 7) 1. Pc7 (targeting and double attack: knight)

8) 1. Da4. The strongest move. Pawn a7 is not to be protected because 1. … a6 2. Pb6+ and 1. … Kb8 2. Dxd7 are not

possible.

Tc3. Bringing in a piece into the attack is a good plan. Big advantage for White because Black has too few defenders. 1. f4.Amove on the wrong side of the board. Of course White remains with the better position.All pieces are still active.

9) 1. Df4 Kg7 2. Txe5 (the pin: attacking a pinned piece )

5) 1. Da4 prevents that Black exchanges an attacker. Double threat.

Le3. The move played but after 1. … Lxd6 2. exd6 White is only more active. Later 1-0 (Lisitsin-Kholmov Kiev 1954) 1. Db5 threatens a lot (i.e. De8+, Da6) but the knight capture solves all threats.

6) 1. Lb1 Dd3 2. Ta2 (the pin: pin)

1) 1. Pxh6+ Lxh6 2. Lh7+ Kh8 3. Pg6# (mate in three)

4) 1. Lf3. Black wants to play c5 (not possible yet) but after a move like Dc7 it is. The move of the pawn weakens White’s centre and activates Lb7.After the move with the bishop Black must be cautious: 1. … Dc7 2. Lf4 Ld6 3. Dc3 and 3. … c5 fails to 4. dxc5.

2) Black is active, the pin of Pc3 comes in handy. Two moves can be chosen, a matter of taste. The position must be opened. 1. … d5. In a better position you should attack the opponent in different areas. Black increases the pressure on e4 and can eventually open the d-file. Capturing is bad for White: 2. exd5 Lh3 3. g3 Df6 and 2.

11) 1. c3. White always wins on the king’s wing. The queen’s wing must remain closed and this move is the last one by White on this side. Why? See the next line.

g5 is the move played in a game (U14), not taking into account the possibilities of the opponent. 1. .. hxg5+ 2. hxg5 Ke6 (now 2. .. c3 3. bxc3 b4 4. cxb4 cxb4 wins or first 2. … fxg5) 3. gxf6 (3. c3!) 3. … Kxf6 4. e5+ Ke6 5.

10) Adifficult position. Black has weak pawns but he is a pawn up. The position is open and if Black can activate the bishop on b7 with c5, White’s position can quickly become worse.

Td1. For Step 4 this is the right move to get a position in which you can find good moves.After 1…. Dxe4 2. Pxe4 Lf8 3. Pxe5 White has won his pawn back.After c5 the knight on e4 must go away but after Pe4-d2-c4 the knights remain active and restrain the bishops.
Tf1.Also a good move. Perhaps the rook can become active and the move prevents that Black grabs the f-file anyway. 1. … Lxa3 2. bxa3 Dxc3 3. Dxe5 is not dangerous and after 1. … Te8 2. Df5 White has enough activity.
Te1. The least of the three.After 1. … Dxe4 2. Pxe4 c5 comes Lb7 to life. It is not entirely wrong, but Black can play. 11) 1. … Pxf4 2. Dxf4 Pf3+ 3. Dxf3 Lxf3 (luring and discovered attack)

1) The vulnerable position of the black king is decisive.. The black pieces cannot immediately help to defend. Black to move would be completely safe after Td4. Therefore White must hurry.

Da2 (the threat Df7+ is too difficult to parry) 1. … Tc4 (1. … Dc4 2. Da7 and the knight cannot be protected) 2. Da7 e4 3. Pe6+.Also without this knight fork the black position is hopeless.Also 3. Td1 (bringing in a piece) or 3. g3 De5 4. Pc6 (elimination of the defender) are winning easily.
Nc6 is better for White but not winning.

5) Black needs some moves to finish his development.Afine move to chase away the bishop and have Td8 at hand. The king can castle or go to f7. That explains why the first move gives a bit more chances.

Pf5. It is good to capture: 1. … Lxf5 2. exf5+ Kf8 3. Le7+ Kg8 4. Tad1 (activity). This also applies to 1. … Kf8
Le7+ Kg8 3. Tad1. Giving up a pawn (deliberately) will not happen often in the fourth step, but Black has some play for the pawn after 1. … f6 2. Pxg7+ Kf7 3. Lh6 Pe5.
Tad1.Agood developing move and after 1. … f6 2. Le3 Td8 White is thanks to the better pawn structure a bit better.
h4. Now too f6 is a good answer but h5 is not a real threat: after 1. … 0-0 2. h5 the move 2. … f6 is adequate (White cannot open the f-file).

Why a hesitation in playing Dg4 is logical? That is because Black wins a tempo with Ph6 to go to f5 and d4.Asingle piece is not enough: after 2. … Ph6 3. Dh3 Pf5 4. Ld3 Lb7 5. Pe4 the knight will enter.

Dd2. Nothing wrong with this move (followed by castling queen side). Developing and finishing the opening (putting pieces on squares where they can do something).
Le2. The idea is good. Taking care that Black will not become inactive on the long diagonal with queen and bishop. Black trusted White and was quickly worse after 1. … Tb8 2. Lf3 (Shouldice-Patino, Haifa 1976).After 1. … Dxg2 2. Lf3 Dxb2 3. 0–0 Lb7 there are no problems.

3) 1. g4 fxg4+ 2. Kxg4 e4 3. Kf4 (or 3. b5) 3. … Kd3 4. b5 e3 5. b6 e2 6. b7. Even if you are not able to calculate all possibilities, still you will decide for 1. g4.

6) 1. Kg1. White must allow perpetual check. You certainly must look for other moves, but if Black gets his bishop into play, you must sense danger. The lines: 1. Kg3 Tg2#; 1. Ke3 Pd5+ 2. Kd4 Tc4+ 3. Kd3 Tf4+ and 1. Ke1 Pg2+ 2. Kd1 Pe3+ 3. Ke1 Te2#.

7) 1. Kc6 Tb8 2. Ta1+ Kb3 3. Tb1+ (chasing and X-ray check) (Fritz 1952)

8) 1. Pb5. White exchanges the bishop of the black squares and gives Black a double pawn. The black bishop that remains is passive and is hindered by his own pawn. In a line 1. … cxb5 2. Dxc7 Lxc7 3. Lxc7 (3. Lxb5+? Kd8)

Lxd6.Agood move too if after 1. … Dxd6 2. e4 will follow.After 1. … Pf4 3. Pxf4 Dxf4 4. Pe2 has White a strong centre.
Tac1.Alazy developing move that costs a pawn (after some captures on f4).

Pxg6 hxg6 2. Pe4 Pf6 and now is playing the knight via d2 to c4 the best. That could have been solved in a more clever

way.

Βήμα 5 mix

1) In this position there is mate on the back rank. Furthermore we see that Td7 is pinned. So elimination of the protecting piece wins material: 1. Te7 Dd8 2. Txd7 (better than 2. Lxd8).

2) Rather a difficult problem to begin with but it serves as an example that the correct approach can help you to tackle quite a lot. The first thing that strikes is the possibility of a discovered or double check. What do we know of that theme? The rules are: the front piece attacks a second target and the front piece chases the king (in a mating net). That is by far not all. Here we can see that: the front piece prevents escaping (front piece becomes guard) and the front piece eliminates a defender.

The primitive 1. Pc5+ De7 brings nothing. Correct is 1. Pe5+ (chases the king, guards square g6 and interferes the protection from the rook on e1. Suddenly we see the rook as a target: it is unprotected now, so there is a second target.After 1. … Kf8 two times chasing is enough for a successful double attack with the queen: 2. Db8+ De8 3. Db4+.

3) Many white attackers and sufficient black defenders, but they hinder mainly their own king. Mate by access is possible: 1. Ph5+ Kh7 2. Dxh6+ Pxh6 3. Pg5#

4) Avulnerable king, enough attackers. The bishop check on e7 leads to a quick mate and therefore luring the knight away will do: 1. … Txd4+ 2. Pxd4 Le7+ 3. Ka4 Txa2+

5) Avoiding stalemate (1. Dxf5?) and not allowing a check on c5: 1. Dc7 Dg6 2. Dg7+ Dxg7+ 3. hxg7#

6) 1. Dh5 Dd3 (1. … h6 2. Lxh6) 2. Te4 h6 3. Lxh6. Bringing in attackers and eliminating the protecting piece by interfering.

7) The vulnerable position of the black king is decisive. The black pieces cannot help to defend immediately. Black to move would be completely safe after Td4. White therefore must hurry.

Da2 (the threat Df7+ is too difficult to parry) 1. … Tc4 (1. … Dc4 2. Da7 and the knight cannot be protected) 2. Da7 e4 3. Pe6+.Also without this knight fork the black position is hopeless.Also 3. Td1 (bringing in a piece) or 3. g3 De5 4. Pc6 (elimination of the defender) are winning easily.
c6 gives Black the opportunity to attack the knight with 1. … Td4.
g3 Dc4 and Black holds the white queen at a distance after both 2. Dd1 Dd5 and 2. Dd2 Dd4.

8) 1. Df8+ (1. Db8+ Kh7 2. Df8 Dg5#) 1. … Kh7 2. Dxh6+ Kxh6 3. Th3#. Both kings are vulnerable. Winning time is essential.

9) 1. … Pxd5 2. cxd5! Pc5 3. a3 and 4. b4 costs a piece, just as 2…. Pg5 does. Capturing with a piece on d5 is a better solution for White (the pair of bishops, better pawn structure).

10) 1. … Dc1+ 2. Dxc1 Tc6+. Defending against a pin by luring away the pinning piece.

11) 1. … Dc4+ 2. Kg1 De2 3. Db8+ Pc8. Entering on the second rank is logical. It is important to see in advance the interposing on c8.

12) 1. Da7+ Lb7 (1. … Kc8 2. Dxb6) 2. Ta6 Db8 3. Dxb6+ Kc8 4. Ta5. Vulnerable black king (only a few defenders). Thanks to the pin after the first move White can bring in the rook.

1) 1. f7 Dxf2 2. fxe8D. Thanks to an in-between move White wins his rook back. He will be two pawns up.

2) The bishop is being attacked. Giving up the pair of bishops is not necessary. Which move with the bishop to choose? The most active one doesn’t take the possibilities of the opponent into account.

… Le7! The bishop can quickly become more active (f5 in a good moment). 1. … Lb6? 2. Lb5. The bishop on b6 doesn’t protect square d6 anymore.
… Tc8 2. Pxc5 Txc5.

3) 1. Dg7+ Txg7 2. Te8+ Tg8 3. Txg8+ Kxg8 4. Td8#. More attackers. The black mating threat forces White to act quickly.

4) 1. … Pd3 2. c7 Pe5+ 3. Kg3. The only square whereby the knight cannot control square c8 with tempo or win the new queen with a knight fork (i.e. 3. Ke4 Pc4 4. c8D Pd6+)

5) 1. … g5+ 2. Kg3 De1+ 3. Kh3 Dh4#. This is mate in three.Also the cooperation of queen and knight is fatal: 1. … De5+ 2. Kg4 h5+ 3. Kh3 Pf7 4. g3 Df5. The human move; the computer gives 4. … Kh7 and 4. … Kg8 as quicker.Also

… De2 5. Kxh5 De8+ 6. Kh4 Dc8 is not obvious.

6) 1. Ta4 Dc8 2. Ta8 (the pin: chasing the front piece and pin).

7) 1. … Pe4 2. Dd4 Dxd4 3. Pxd4 Pxc3 4. bxc3 Txb1+. Exploiting the pin on the b-file. Preparatory move: targeting. 8) 1. d4+ Dxd4 2. Tb5+ Dd5 3. d4#. Winning time. The pawn sacrifice eliminates the queen as a defender with a pin. 9) 1. Dc8 (1. Tbf1 g4+ 2. Kh4 Th2+ 3. Txh2 Txh2#) 1. … g4+ 2. Dxg4+ Pxg4 3. Kxg4 (defending against mate) 10) 1. b5 Pc5 2. Lxc5 bxc5 3. Db8+ (elimination of the defence: chasing away+capture and double attack: queen)

11) 1. Pd4+ Kxe3 2. Lb6!. Setting up a battery and zugzwang (every move will cost the bishop).

12) 1. Pf7+ Txf7 2. Dxf7 Df8 3. Txa8 Dxa8 4. Dxg7#. The check by the knight serves to activate the queen, Black must take (1. … Kg8 2. Pe7#). Black can protect g7 but the queen can be lured away in an easy way.

1) 1. Pb5 cxb5 (1. … Dc5 2. Pc7+) 2. Lxf7+ Kxf7 3. Dxa3 (line clearing and discovered attack)

2) 1. Df7 De5 2. Pf8+ (luring, chasing and double attack: knight)

3) 1. Txd6 (1. Pxf8? Lc5+ 2. Kg3 Txd1 3. Txd1 Lg1) 1. … cxd6 2. Pxf8 (defending against a passed pawn) 4) 1. … Pxe5 2. fxe5 Dxe5 3. Lf4 (trapping)

5) 1. Kg5 (1. Kh5? Kg7 ; 2. e6? Te7) 1. … Txe5+ (1. … Kg7 2. Ta7+ Kh8 3. Kf6 Tf8+ 4. Tf7) 2. Kg6 Te8 3. Kf7 Te1 4. Th6# (Ulrichsen 2001) Exploiting vulnerability: a bad position of the king.

6) 1. … Pf3+ 2. Kh1 Pxg3+ 3. Pxg3 Th2# Exploiting vulnerability: a bad position of the king. 7) 1. … Lc6 2. Dxd8 Lxd8 (trapping)

8) Difficult? No, not with the correct approach. Mate on the back rank catches the eye. The queen on d6 must ‘disappear’. Don’t forget the unprotected rook on a6. The first move is logical: 1. c5 Lxc5 (to refute 1. … Dd8 the unprotected rook is needed 2. Dc4 Txa5 3. Dxd4) 2. Dxc5 Dxc5 3. Tb8+ Te8 (Easy to miss but harmless here because White is already a piece up) 4. Txe8+ Df8 5. Txf8+.

9) Danger of stalemate because the bishop controls b8.

Ld6. Giving away the bishop is logical. Why on d6 will become clear from the next alternative.After 1. … Txd6+ 2. Db6 Black would have to pass.After 2. … Txb6 3. axb6 is the appropriate move!
Lf6?. The wrong choice because after 1. … Txf6+ 2. Db6 Td6! (and not 2. … Txb6+? 3. axb6) Black will be stalemated after 3. Dxd6 and 3. Kb5 Txb6+ 4. axb6 Kb7 as we know since finishing Step 3.
Db6? Txb6+ 2. axb6 (2. Kxb6) is stalemate.

8) White is better due to a better pawn structure.All normal moves are possible to maintain that small advantage. But how to increase it?

Pb5. White exchanges the bishop van d6.After 1. … Db8 2. Pxd6+ (postponing the exchange is maybe even better because the bishop cannot go away, i.e. 2. Tfe1) 2. … Dxd6 3. Lf4 the bishop becomes more active and the black king is somewhat vulnerable.
g3. Disadvantage is that Black can play 1. … Pe4: 2. Dc2 Pxd4 Pxd4 Ld7.
Tfe1. Nothing wrong with this move but now also 1. … Pe4 is possible and after 2. Dc2 exchanging on d4 followed by the pin on g4.

6) Black has sacrificed a pawn. He has no lead in development and the question is if Lg4 is so useful, because b7 is weak. How does Black win his pawn back or gets compensation?

… f6. You will find this move by thinking it through, even if it would not be given away in the list of three. The e-pawn must advance but as it will turn out later the move e6 is too slow. Now e5 will follow on the next move. White cannot allow himself wild actions as 2. b4 e5 3. Lg3 Pxb4 4. Db3 Lxc5 5. a3 Pc6 6. Dxb7 Pge7.Actions with a single piece are most of the time not dangerous.Also 2. a3 e5 3. Lg3 is not good for White because after 3. … a5! 4.

… Pf6.Adeveloping move but not good enough to get compensation for the pawn. White can play 2. Pe5 (without Pc6 the move b4 will be possible) or 2. Db3. Black will not win his pawn back so easily and if he does White is ready with his development.

3) White is two pawns down. Winning one back is easy. In what way does he keep the most chances for a draw?

Dxa4. Rules of thumb are useful but never apply them blindly. Exchange no pieces when you are material down. Helpful rule rule but more important is what will be left on the board. With exchanging queens White can make many black pawns weak: 1. .. bxa4 2. Tfd1 (strong: the threat to win d6 forces to passivity and lures a rook away from the back rank – 2. Tc4 is not handy because 2. … d5 can follow and stupid because 2. … Pd2 wins) 2. … Tc6 3. Tc4 f5 4. g4 with a lot of play. Still two pawns downs but that will change quickly.
Lxe4 Dxe4 2. Dxd6 Dc6. It wins a pawn but Black is a healthy pawn up, no weaknesses and a majority at the queen’s wing and that will produce later a passed pawn.

be glad if he doesn’t get worse. Just too few attackers and sufficient defenders.After 1. Df5 Dxc4 you must sense that a

queen and a knight against a superior number of pieces is not enough. What is correct?

Lxe5 Dxe5 2. Tfe1. Exchanging is good in this case.All white pieces become active and the d-pawn is not weak but also poses no danger (2. … d4 3. Pg3).

White resigned because of 2. Ke5 Kg2 3. Kf6 Kxh2 4. Kxg6 h3 5. g5 Kg3 6. Kf7 h2 7. g6 h1Q and Black wins against a g-pawn on the seventh rank.

Strategy – Mini plan: A 1) 1. … exf5

Black captures away from the centre (the rule is: capture towards the centre!) but the knight gets a nice square on e6. 2) 1. La3

Otherwise 1. … d5.

… Te8 2. Ld6 Dd8 3. Pe2 e5 4. Pg3 with a big advantage for White. ( eisgerber-Van den Bosch, Bad Nauheim 1936) 3) White weakens the black pawn structure: 1. a5 cxb4 2. Pxb4 Df6 3. Pc6 Tb7 4. f3 bxa5 5. Txa5 and White is better.

(Hemingway-Wade, Huddersfield 1953) 4) 1. f3

But 1. c5 dxc5 2. La3 b6 is not good.After f3 the white bishops come to life. The rest of the game is instructive. 1. … h5

After 1. … exf3 White plays 2. Lxf3.

5) 1. g5

First of all to prevent Black from closing the kingside with h6. White not only prepares h4-h5 to open files, but the move also frees the way for the white bishop. The e6-square is waiting. 1. … Kg8 2. h4.

6) 1. … Pxc4

Black must make the white bishop harmless. The move does not lose a piece! On 2. Dd3 there follows 2. … Dh4. In the game Van Dongen-Van Beek, Leiden 1997 Black played the weaker 1. … Dc7 2. Dd3 g6 3. Pe3 Pc5 4. Pg4! f6 5. Dd4. The mating pattern  also remains in the position after 5. Lxf6!

Lxh7+ Kxh7 3. Dd3+ Kg8 4. Dxc4 Pf6 and Black might be better. 7) 1. … e6

This move hits the nail on the head. The white pressure suddenly is gone, the c4-pawn is difficult to protect. 2. f5?

After the better 2. Da2 exd5 3. cxd5 Df7 Black has the advantage too.

… exd5 3. fxg6 Pxc4. White resigns. (De Gorter-Frank Erwich, Wijk aan Zee 1998)

8) The knight on f6 is centralised but isn’t doing much. Therefore 1. … Ph5, on its way to f4. In the game Harinck-Marc Erwich, Leiden 1996 Black took on d2 and lost a great deal of his advantage.

9) 1. Lh4!

Maintaining the tension. White doesn’t need to fear 1. … g5 2. Pxg5 hxg5 3. Lxg5. White wins the piece back with 4. e5. After 1. Lxf6 Dxf6 2. Pe5 De7 White has insufficient compensation for the pawn.

… De8

On any other move there follows 2. e5.

Lxf6 gxf6 3. Pd2 Kh7 4. Lf1 b5 5. Df3 f5 6. Df4 Pb3 7. Pxb3 cxb3 8. Ld3 and White is better due to the weak black pawns. (Romanishin-Savon, Erevan 1976)

10) Drawing 11) Drawing

12) Black weakens the black pawn structure: 1. Txc8 Dxc8 2. Pf5 exf5 3. Dxd5 Pc5 3. … Dc2 is followed by 4. Lxg7.

Lc4 De6 5. Dxe6 Pxe6 6. Td1 and White is better. (Flohr-Veltmander, Tartu 1950)

Strategy – Mini plan: B 1) 1. … e5

not only prevents e5 but also creates a strong square for the knight on e5. White cannot maintain the f4-pawn. 2. fxe5

After 2. g3 comes 2. … Lh6 3. Lg2 exf4 4. gxf4 Ph5. 2. … Pxe5 3. d3 Pfg4 4. De2

Also after 4. Lxg4 Pxg4 5. Lc1 (5. De2 Tce8) 5. … Pe3 Black is better.

… Pe3 5. Te1 f5 6. exf5 Pxf3+ 7. gxf3 Txf5. (Pickard-Lein, Dallas 1996) 2) 1. a4

Logical because the black pawn structure has been demolished. (Pogrebyssky-Levenfish 1939) 3) 1. … Pc8

Black must activate his knight. From f5 it attacks a pawn.

Pf1 Pe7 3. Pg3 Lxg3 4. Txg3 Pf5 5. Th3 c5 with the advantage. Black plays for a second white weakness. (Lein-Jansa, Borgarnes 1985)

4) 1. d5

Alogical move. White activates his pieces. In the game Black refused the pawn sacrifice. The position after 1. … exd5 2. Pd4 g6 3. e6 Lc8 4. De5 seems fine for White, although he must take care of his e-pawn.After 4. … Pc7 5. Lxf5 Pa6 6. Tb1 gxf5 7. Te1 f4 8. Dxf4, White has more than enough compensation for the piece.

… Pb6 2. d6 now the white advantage is unmistakable.

5) Black is better after any move. The white pieces are hindering each other. The 9 year old Jankiel Ferrol chose the strong

… a5 to exploit the vulnerability of the position of the white queen. The threat is to trap the queen.After 2. a4 b5 3. axb5 Lxb5 the threat is again a4.

6) 1. … Dh4+!

Black dropped a piece in Reisinger-Hoy, Duitsland 1992 with 1. … Pxd4 2. Pxd4 Dh4+ 3. Df2 2. g3 Df6.

Black has weakened the f-pawn. The bishop on b7 is much more active now. 7) 1. … g5

Black must prevent f4.After 1. … Tce8 2. f4 T5e7 3. Tcd1 Black has to reckon with f5. 2. f4

White has no time to play 2. Pd1 Pxd5 3. exd5 Dd4! 2. … gxf4 3. Dxf4 Tce8 4. Tf1 T5e7 5. e5

Otherwise Pd7-e5. Black took the pawn and the rest was easy. (Ligterink-Psakhis, Plovdiv 1983) 8) 1. b4

White keeps the knight on a6 passive.

… Dc8 2. Lb2 Te6 3. Pb5 with the advantage due to the limited mobility of the black pieces. (Marjanovic-Forintos, Bär 1980).

9) 1. … Lc8

You shouldn’t exchange off the weaknesses of your opponent too easily. Black can take b4-pawn whenever he wishes. The bishop is also activated. 2. g5 hxg5 3. Lxg5 Lb7 4. Kh2 Txb4 5. b3 Tc8 6. Te3 and Black won easily. (Stolz-Boleslavsky, Groningen 1946)

10) 1. … b5!

It would be a sin to remove the knight from the centre (after 2. Ld3 that would be the case). Black creates with b5 a strong square on d5. The protected passed pawn can be blockaded.

c5 a6 11) 1. Pd1

On its way to f5 and the white attack will be unstoppable.

… Tc8 2. Pe3 Tc7 3. Pf5 Tf8 4. Dd1 f6 5. f4 exf4 6. Dh5 Pe5 7. Dh7+ (Benko-Najdorf, Los Angeles 1963) 12) 1. Pd3

White forces a very strong centre with a pawn sacrifice. 1. … exf4 2. e5 fxg3 3. hxg3 Dg5 4. Pf4

Black gave up a piece on c4, but he couldn’t save the game anyway. (Polugaevsky-Geller, Riga 1958)

Strategy – Mini plan: C 1) 1. Tg3

White must conquer the square d5 for his knight. For that purpose 1. b3 is not clever because of 1. … Lxb3! 1. … Tg8

There is no choice; the king must keep on protecting d6; 1. … Lb5 2. c3 does not help much. 2. f6+ and White wins material.

2) 1. … Pxe4

The white pawn sacrifice is correct indeed after 1. … dxe4 2. Pg5 or 1. … De7 2. e5. 2. Pxe4 De7!

Capturing is not obligatory.After 2. … dxe4 follows 3. Lc4 De7 4. Pg5 and White is better.After the queen move the white pawn sacrifice is hardly successful.

3) 1. b4

White will conquer d4 for his knight. 1. … Le7

The bishop must go back: 1. … Ld4 2. Tb1 0 ¬0 3. Pxd4 Dxd4 4. Le3 2. a3

In the 19th century sacrificing was very popular, but the positional pawn sacrifice hardly existed. Now with 2. … d4 Black can develop sufficient counter play. Maybe therefore 2. Df2!? In this game White was right.

… f5 3. Tc1 Lb7 4. Le3 Dd8 5. Pd4 Pf8 6. 0-0 with fine piece play. The knight on d1 goes to a5. (Steinitz-Sellman, Baltimore 1885).

4) 1. e5

White must open more lines.After 1. Ph2 c6 2. f4 d5 Black shuts off the important attacking bishop on b3.

… De7 2. Tfe1 Tbe8 3. Dd2 dxe5 4. Txe5 Dd6 5. Dg5 Txe5 6. Pxe5 Db6 7. g4 Ld6 8. Pxf7 Txf7 9. Df5 g6 10. De6 Kg7 11. Dxf7+ Kh6 12. Le6 (Alekhine-Duras, Saint Petersburg 1913)

5) 1. Dxc5

White plays for the d6-square.Adifficult task, but since you know the white plan, it’s a piece of cake now. The move order with 1. e5 is also good.

… dxc5 2. e5 Lxf3 3. Txf3 Pd7 4. Pe4 Ke7 5. Tg3 Thg8 6. Td6 with a big advantage (Polugaevsky-Koto , Moscow 1961)

6) 1. Lc4

This modest move is the best. Capturing on e6 strengthens the black centre and gives up the position of the knight on f5. On c2 the bishop is too passive. The possible doubled c-pawns are not weak.

(Keres-Tarnovski, Helsinki 1952) 7) 1. De3

Attack the weak points of your opponent. The h6-pawn cannot be protected. 1. … Kh8 2. Txg7 Kxg7 3. Tg1+

(Bellon-Alonso, Cienfuegos 1996) 8) 1. a4

White is going to attack (and win) on the kingside, except there are too many distractions on the other side. Therefore, White shuts the queenside at the moment when Black cannot capture en passant (the a5-pawn will then be incurably weak) (Gurgenidze-Polugaevsky, Tbilisi 1956).

9) 1. f4

The pawn on f5 is weak but difficult to attack. White threatens to take on e5. The move 1. Lb2 is also good. Black cannot answer with 1. … f4 because of 2. Lg4.

… e4

Or 1. … Tgf8 2. Lb2 with the threat 3. Ld3 and 1. … exf4 is followed by 2. Lxf4 2. Lb2 Dg6 3. Lh5

10) Awkward again, but if you have seen it once it is easy. In this kind of position White is always better (more mobility for his pieces), but to make progress is another story. Here you will manage with:

In the game Frank Erwich-Havelaar, Wijk aan Zee 1998 White played the less strong 1. Tcd1. 1. … Td8 2. cxd6 Txd6 3. Txd6 exd6 4. Pb4 and the black pawn structure is vulnerable.

11) The slogan is: increase your activity. The knight on f6 is vulnerable because it can be pinned along the long diagonal. 1. Pce2

As it turns out from the following moves the knight on g3 has one more attacking task. 1. … Dd7 2. Db2 De7 3. Pd4 Kg8 4. Pxc6 with a winning position.

(Smyslov-Suetin, Moscow 1952) 12) 1. … Pe8

You should know that a protected passed pawn possibly is best blocked by a knight. The knight on d6 has a good position. It supports the advance f5 (and sometimes b5). (Jezek-Uhlmann, Praag 1956)

Strategy – Mini plan: D 1) 1. … Pe6

Forces the pawn forwards so that the bishops becomes less mobile.After 1. … cxd4 2. cxd4 exd4 3. Lxd4 Pe6 4. Le3 Pc5 5. Lxc5 bxc5 Black has a better bishop ending, but the advantage is much smaller than in the game.

d5 Pd8!

On the way to a5 to attack c4. The pawn cannot be protected sufficiently any more. 3. Kf2 La6 4. Ke3 Pb7 with a decisive advantage. (Shipman Fine New York 1945)

2) 1. Lf1

Black was threatening to undermine the knight with 1. … a5. White remains better because of the more active minor pieces, although, the advantage after 1. … Pb7! is not big. Black played 1. … Pe6? and lost one of only 36 games he lost during his caree . (Eliskases Capablanca, Semmering 1937)

3) 1. f4

The pawn structure must be broken up before Black strikes with Kd5 and e4. 1. … Lf7 2. fxe5+ Kxe5 3. Pc5 with a winning advantage.

(Ludden-De Vreugt, Hoogeveen 1997) 4) 1. … h5

Black creates a distant passed pawn.

Ke3 g5 3. f4 exf4+ 4. gxf4 g4 5. f5 f6 6. Lf1 La4 7. Pc5 Lc1+ 8. Kd4 Ld1. White resigned. ( isier-Gligoric, Montilla 1978

5) 1. … a6

Opening files to support the knight on c4. On its own a piece on a strong square can do nothing. 1. … h6 2. a4 a6 3. Le3 is not necessary

bxa6 Txa6 3. Lg5 Tfa8 4. Pc1

Black’s position is good. The white pawns are weak and easy to attack. 6) 1. … g5

Defends the strong square.Also 1. … Lh6 is possible. The pawn move is less flexible but the bishop can remain active on the long diagonal. (Podgorny-Pachman, CSR 1954)

7) 1. Kh1!

The white rooks are doing nothing in this position and Black is vulnerable down the f-file. To occupy the square in front of the doubled pawns is a good plan, except that the knight cannot get there: 1. Pe2 f5! 2. exf5 (or 2. Pg3 f4 3. Pe2 d6) 2. … d5.

… d6 2. f4 Le6 3. Lxe6 fxe6

This exercise belongs to chapter 9. White is fine, but how should he continue? (Larsen-Zuidema, Havana 1964)

8) Drawing 9) 1. c4

Black gets a mobile majority if he can play c4. (Lasker-Tarrasch, Germany 1908)

10) 1. Ph4

To the edge, but on its way to the strong square f5. 1. … Te5 2. g4 Pb4 3. Pf5.

White won in Didishko-Kasparov, Minsk 1978. Black was 15 years old at the time of this game. 11) 1. Ta1

Other moves promise less advantage: 1. e5 Td8 or 1. Td1 Pa6 2. Td7? (a better move is 2. b5 Pb8 3. Ta1 a6 4. Tc1 axb5 5. Lxb5+ Kb7) 2. … Pb8!

… a6 2. Td1 Tf8 3. Td7 Kb8 4. e5 with a winning position. (Smyslov-Matanovic, Monaco 1967) 12) 1. … Pc5

Thanks to the knight on a5 Black can play his knight to d3.Ahuge improvement of his activity.

In the rook ending after 2. bxc5 Txc5 3. Pxc4 Txc4 White has weak pawns.

In the game Aaron-Botvinnik, Leipzig 1960 the black knight came in with 2. … Pd3 and Black won.

Opening – Which developing move?: A

1) a) 1. Dd6 Not a bad move. White is better because the queen is difficult to chase away from d6. b) 1. Ld3Adeveloping move, that causes Black no problems.

c) Pa4!

Moving the same piece twice is very good here. White threatens to win material with 2. Pb6 and 3. Pxc8. Black opted for sudden death with : 1. … Pbc6? 2. Lb6 (winning the queen). (Hector-Vidarsson, Reykjavik 1996)

2) a) 1. Pf3 Bad, Black wins with 1. … Pe4 2. Lh4 Dxh4. b) 1. e3

The correct move. White parries both threats (… Pe4 and … Lxf2). c) 1. Pc3 prevents 2. … Pe4 but now 2. … Lxf2+ wins.

3) a) 1. … Le6

This move is recommended by theory. White can win his pawn back with 2. Lxe6 fxe6 3. Db3 but after 3. … Dd7 Black has adequate play.

b) 1. … Lc5 Black must reckon with 2. Pg5 Ph6 Pxf7 Pxf7 4. Lxf7 Kxf7 5. Dh5+ after which it is White who is better. He gets his pawn back.
c) … Lg4? The worst of the three.After 2. Db3 Dd7 3. Lxf7+ (but not 3. Dxb7? Tb8 4. Lxf7+ Kd8 5. Da6 Lxf3 6. gxf3 Tb6 7. Dc4 Pe5) 3. … Dxf7 4. Dxb7 Tc8 5. Dxc6+ Ld7 6. Da6 Pf6 7. e5 Pe4 8. Te1 Pc5 9. e6 Pxe6 10. Pg5 Black resigned. (Pytel-Castro, Dortmund 1977)

4) a) 1. … e6

The best. The action of b) gains nothing now: 2. Pg6 fxg6 3. Dxg6+ Ke7.

b) 1. … e5 Good move, except after 2. Pg6 fxg6? ( 2. … Lb4+ is better although White is fine after c3 fxg6 4. Dxg6+ Kf8 5. cxb4 exd4 6. 0-0) 3. Dxg6+ Ke7 4. Pf5#
c) … Pgf6 White gets an advantage with 2. Pg6 Tg8 (2. … Pc5 3. Dc4 fxg6 4. Dxc5 is also better for White) 3. Lf4. 5) a) 1. Pf3?After 1. … Pb4 is White has serious problems.

b) 1. a3?After 1. … Pd4 White solved these problems by r (Kox- elling, Eindhoven 1973) c) 1. e3 Black does have compensation for the pawn after 1 … Pb4 2. Lb5+ Ke7

6) a) 1. … dxe4 is dangerous for Black after 2. Pg5! (not 2. Pxe5 Da5+). b) 1. … Ld6

The best move. Black maintains his centre.

c) … Lg4 Too active. Namely, after 2. exd5 cxd5 3. h3 Black must take on f3 and it is a waste of time and of the bishop. 7) a) 1. … Lxd2+

The winning move.After 2. Dxd2 Pc6 3. Td1 e5! Black has superior play.

b) 1. … Dxd4 Too greedy. Black is lost after 2. Lxb4! De4+ Le2 Dxh1 4. Dd6! Pc6 5. Lf3! Pxb4 (5. … Dxg1+ 6. Ke2 Pd4+ 7. Dxd4) 6. 0-0-0! (Griffith-Brainin 1943)
c) … Pc6 Does not cause much trouble for White, after 2. Lxb4 Pxb4 3. Pf3 Pc2+ 4. Dxc2 Dxf3 5. Tg1 0-0 6. Lg2. 8) a) 1. … h5

Black’s position is worse, but still playable. Black continues with Pe7, g6 and Pf5.

b) 1. … Dc7 attacks e5, but after 2. Ld4 the queen just becomes vulnerable on the open c-f

c) … f5 Opening the position when you are behind in development is not a good strategy: 2. exf6 Pxf6 (better 2. … Dxf6 3. Ld4 Ph6 4. Dh5+ Df7 5. Dg5 and White is better) 3. Dg6+ and mate. (Pulnikov-Oserov, Togliatti 1984)

9) a) 1. … Pb4

Acorrect decision.After 2. Lc2 (2. Da4+ Ld7 3. Db3 Le6 4. Da4+ Dd7 of 2. Lb5+ c6) 2. … Dxd1+ Black has a decisive advantage. (Guinari-Rastrelli Bologna 1925)

b) 1. … f6 White does not accept the pawn sacrifice and plays 2. 0-0 Pgxe5 Lxe5 fxe5 4. Lb5. c) 1. … Le6Apassive developing move. Black must show how he gets his pawn back after 2. 0-0.

10) a) 1. Te1 Black can castle. b) 1. Lxf6!

The point is that after 1. … Dxf6 2. Pxe6 follows. White is better in any case: 2. … Lxe6 3. Lxe6 fxe6 (3. … Dxe6

Te1 of 3. … 0-0 4. Ld5) 4. Dh5+. Black must take with the g-pawn and that appeared to be good for White in the game Sutovsky-Bykhovsky, Tel Aviv 1995: 1. … gxf6 2. Dg4 (Black has difficulties developing.) 2. … Lxd4 3. cxd4 h5 4. Dg7 Ke7 5. d5! Dg8 (5. … exd5 6. Lxd5! Dxd5 7. Dxh8 Lh3 8. Dg7) 6. d6+ Kxd6 7. Dxf6 Ld7 8. Tfd1+ Kc7 9. Le2
c) De2 Black can castle.

11) a) 1. … a6 chases the bishop to a better square. b) 1. … Pe4

The best move. White is not yet fully developed. Furthermore, two pieces are unprotected and the winning 2. … Da5 is being threatened.After 2. Da4 (2. Le3 Da5) 2. … Lc5 3. Le3 Lxe3 4. Txe3 Df6 Black has a huge advantage.

c) … Le6 Passive defence is not necessary. 12) a) 1. c3

The best move.After 1. … Le7 2. Da4 Ph6 3. Pe4 0-0 (3. … Pf5 4. Td1 b5 5. Dc2) 4. Lxh6 gxh6 5. Tfd1 De8

Dxd7 Lxe4 7. Dxc7 Lc5 8. b4 Le7 9. Pd4 Lxg2 10. Kxg2 Dd8? 11. Pxe6 White obtains a decisive advantage. (Quiteros-Miana, Argentina 1975)
b) Te1 Weakens the f2-square, so Black always wins a tempo with Lc5.
c) De2An ordinary move in this kind of positions. The queen is not always happily situated on e2 because of a5 en La6.

Strategy – Knight against bishop: A 1) 1. Pa4!

White must block the black doubled pawns. In that way the bishop remains bad.

… De7 2. Dd4 Tfb8 3. Pc5 a5 4. a3 Kf7 5. Ta1 Tb5 6. b4 Tab8 7. c3 with a big advantage. (Em. Lasker-Cohn, St. Petersburg 1909)

2) 1. Dxd4

When there is a bad bishop it is good strategy to exchange the remaining pieces. 1. … Dxd4

After 1. … cxd4 2. Le5 Kg7 3. Lxf6+ Kxf6 4. b4 La6 5. Pf3 d3 6. cxd3 Lxd3 7. Pd4 Lb5 8. Pxb5 cxb5 9. g4 White

wins the pawn ending.

Le5+ Kh7 3. Lxd4 cxd4 4. b4 La6 5. Pxf5 d3 6. cxd3 Lxd3 7. Pd4 (Sax-Szell, Hongarije 1984) 3) 1. … c4

Creates a bad white bishop. In a closed position the knight does a better job.

Ph4 g5 3. hxg6ep fxg6 4. f4 h5 5. Tf3 Kd7 and Black won. (Evans-Lein, South Bend 1981) 4) 1. Pxe6

Exchange pieces!

… Lxe3 2. Pxd8 Lxd2 3. Pxd2 Taxd8 4. exf6 Txf6 5. Pb3 and White reaches the ideal position, the knight can block the pawns. (Karaklajic-Hall, Bognor Regis 1968)

5) 1. Lxf5

Exchanging so as to be left with a knight against a bishop. 1. … Dxf5 2. Pxc6 Lxc6 (Wolff,P-Wen, Canada 1991)

6) 1. … Lxc3

Asurprising exchange. Five moves later the power of it can be seen.After 1. … Pe5 2. Pb5 White is better and also after 1. … Pb6 there follows 2. Pb5.

bxc3 Df6 3. Ld2 Pe5 4. Tfb1 Tfb8 5. Txb3 Txb3 with a huge advantage. (Quinteros-Panno, Buenos Aires 1968) 7) 1. … Lg4

Exchanging the bishop first and after 2. Df4 Lxf3 3. Dxf3 De7

luring the pawn on to the colour of the bishop. 4. e5 Pd5 with a better game.

8) 1. … Dxd8

After the queens are exchanged the bad position of the black king is not important anymore. 2. Dxd8 Pd6 3. Dxg8+ Kxg8

9) 1. .. Lxc3

Black exchanges all pieces that control square e4. Capturing on c3 immediately gives White a weak c-pawn.Also 1. … Lf5 2. Ld2 Lf5 is possible because White can’t play away his knight.After 2. bxc3 Lf5 3. Lxf5 Dxf5 4. g4 De6 5. La3 Pe4+ Black won without much effort (Makogonov-Botvinnik, Sverdlovsk 1943).

Strategy – Good + bad bishops: A 1) Drawing

2) 1. … Pa7

The knight is not well placed on c6 and from a7 it prepares the useful exchange of bishops. White’s play is far from perfect, but it is instructive.

Pe5 (2. Dd3 De8) 2. … Lb5 3. Lb2 Lxc4 4. Dxc4 Dd5 5. Dxd5 exd5 6. Tc1 Pb5 7. 0¬ 0 (7. Tc5!?) 7. … Pe4 8. Tc2 Ped6 9. Lc1 and Black is excellent (Blumin-Fine New York 1939)

3) 1. Le2

The bishop on c8 covers the weakened squares. Exchanging is the right plan.

… Dh6 2. Lg4 Pd7 3. Pf3 Pb6 4. Lxc8 Texc8 5. Db3 Lf6 6. Ph4 Df8 7. Pf5 and White had no problem winning. (Ståhlberg-Wade, Birmingham 1951)

4) 1. … b5!

The white pawns are tied down on the black squares. The move played is better than 1. … g5 2. Tf2 g4 3. a4. 2. Df3

White is not willing to wait and gives up a pawn.

… bxc4 3. Dxc6 Dxf4 4. Dxc4 e5 5. De2 exd4 6. Td3 dxc3 7. Txd7 Txd7 8. Txd7 Ld4+ 9. Kh1 Dc1+ and White resigns.

(Kmoch-Alekhine, Kecskemet 1927) 5) 1. … Lg4!

It is not the bishop on d6 which is the worst piece on the board, but the bishop on g3.After the exchange on f3 this bishop gets sentenced to life imprisonment.

h3 Lxf3 3. Dxf3 Dxf3 4. gxf3 f6 5. Kg2 a5 6. a4 Kf7 7. Th1 Ke6 8. h4 Tfb8. On the queen’s wing Black is playing with a bishop up. (Winter-Capablanca, Hastings 1919)

6) 1. … Lf8!

Black activates his bad bishop. The move is possible because after 2. Txf6 Le7 the rook is trapped.

Td2 Kg7 3. Ld3 Lb4 4. Kc2 Pc5 5. a3 Lxc3 6. Lxf6+ Kxf6 7. Kxc3 Td8 with the ideal position for Black.

(Tarrasch-Euwe, Bad Pistyan 1922) 7) 1. g4!

White has the advantage of the good bishop. He must create a second front. 1. b4 a5 is bad (or 1. … Ta8) and Black gets counter play.

… Lc8 2. h4 g6 3. Th1 Kg7 4. h5 Th8 5. Tfh2 Ld7 6. g5 and White decided the battle on the kingside. (Tarrasch-Teichman, San Sebastian 1912)

8) 1. … Da4

Black forces the exchange of a rook. The passed pawn was decisive. Not much is gained by 1. … Txc2+ 2. Dxc2 Dc4 3. Db2 Kg7 4. Ld2.

Txc4 dxc4 3. Db1 c3 4. Lc1 Dd1 (Korotylev-Neverov, Petersburg 1993) 9) 1. c3!

Black threatened to exchange the bishops with … Lb5.

… Lb5 2. Lb1 Pc6 3. Lc2 Taa8 4. a4 La6 5. b4 b5 6. Teb1 Tac8 7. Ld3 Pa7 8. Ta3 Tc7 9. a5 and the bishop on a6 acts like a pawn (but one which may take backwards)

(Sokolov-Vaganian, Minsk 1986)

10) 1. La4! (Kasparov-Giorgadze, Minsk 1979) 11) 1. … Lxc3

The bishop on c6 is better than the one on g2.

Dxc3 De5 and Black is slightly better. (Najdorf-Bronstein, Budapest 1950) 12) 1. … Dd7!

The bishop on d2 is the problem child, not the bishop on e7. White can only live with a passive bishop if the rook on f1 can join in. That is prevented by the move of the queen. The gain of tempo after 1. … Td8 2. Tc1 Dd7 3. Le1 is therefore not so good.

Lc1
Td1 is followed by 1. … Td8.
… a4 3. Dc2 Tc8 4. De2 Dd5 5. a3 b3 6. e4 Dc4 7. De1 Dc2 8. f4 Lc5+ 9. Kh1 Ld4 10. f5 Lxb2 11. Lxb2 Dxb2 White resigned. (Tylor-Alekhine Hastings 1936)
