1. d4 Nf6 2. c4 e6 3. Nf3 b6 4. g3 Bb7 5. Bg2 Be7 6. O-O O-O { So far, we ave a boring old Queen's Gambit. But now I adopt a vigorous sacrifice that was popular briefly around 1980, thanks to the patronage of Grandmaster and theoretician Lev Polugayevsky. } 7. d5 exd5 8. Nh4 { This unleashes the power of the bishop on the h1-a8 diagonal. The departure of the pawn from e6 makes the f5-square available. } 8... c6 9. cxd5 Nxd5 10. Nf5 { In the past dozen years this position has been carefully examined, and the revised Encyclopedia of Chess Openings had to devote a lot of discussion to it. At the time, however, it was not clear what the best move for Black was. } 10... Nc7 { This move has survived the test of time. } 11. Nc3 d5 { Black establishes his stake in the center. White must react quickly to reduce Black's central control. } 12. e4 Bf6 13. exd5 { Now 13.Bf4 is more established, but White cannot establish any advantage against best play. } 13... cxd5 { 13...Nxd5 14.Nxd5 cxd5 15.Ne3 } 14. Bf4 Nba6 15. Re1 { This is the critical position. Now it seems that Black can equalize with an attack on the f5-square. } 15... Qd7 { A serious mistake, which walks into a powerful pin on the h3-c8 diagonal. 15...Bc8 16.Qh5 g6 17.Nh6+ Kg7 18.Qf3 Bg5 was seen in a 1986 game. Black has no problems. } 16. Bh3 { I have a strong threat here. Do you see it? Suppose Black plays Re8. How would I win? } 16... Kh8 { 16...Rfe8 17.Nh6+ } 17. Ne4 { This move takes advantage of the new pin on the d-file. } 17...

Qh5 g6 22. Qh4 Bxa1 { Nothing matters now. } 23. Nf6+ { Here Black resigned, because mate comes quickly. } 23... Kg7 24. Qh6+ Kxf6 25. Bg5# 1-0

O-O Nbd7 { This simple move is the primary cause of Black's later difficulties. 13.. .Ne4 14.Na4 Nd7 } 14. g4 { The unexpected advance of the pawns on the king-side is fully justified: it seriously restricts Black's knights and promises to overgrow into a serious attack, while the bishop on c5 cannot take part in the coming battle. } 14... Be4 { 14...Bg6 15.Ng3 Ne5 16.g5 Nfd7 17.Nce4 is better for White due to his kingside initiative. } 15. Ng3 Bxg2 16. Kxg2 Nf8 17. g5 N6d7 18. h4 Ne5 { Black's last chance to generate any counterplay was connected with the moves 18...Rc8, 19...Bb6 and 20...Nc5. } 19. h5 { Played with the option of loosening Black's kingside with pawn h6. } 19... f6 20. Nce4 { With Black's dark squared bishop unable to defend his kingside, White in effect is attacking with an extra piece. } 20... fxg5 21. Bxg5 Qb6 22. h6 Nf7 23. hxg7 Nd7 24. Nf6+ Nxf6 25. Bxf6 { It is difficult to say where Black could have played more strongly. White simply throws his forces onto the kingside. White now threatens to win the Black's bishop with 26.b4. } 25... Qb5 26. Rh1 Bb6 27. Qf3 Ne5 28. Nf5 Nf7 { 28...Nxf3 would allow White a mate in one. } 29. Rxh7 { With this sacrifice, Black resigned since he has no way of stopping the numerous threats; 29...Kxh7 would allow White a forced mate. } 1-0

1. d4 Nf6 2. Nf3 e6 3. c4 d5 4. Nc3 Be7 5. Bg5 h6 6. Bh4 O-O 7. e3 b6 { This is the Tartakower Variation of the Queen's Gambit Declined, a subtle and refined opening which has held great appeal to Karpov. } 8. Rc1 Bb7 9. cxd5 exd5 10. Be2 Nbd7 11. O-O c5 12. Qc2 a6 13. Rfd1 { The Tartakower Variation requires good positional sense and an understanding of the dynamics of this particular pawn structure. } 13... c4 { Although White did not capture at c5 on move 12, he is now ready to do so, and that is why Karpov advanced the pawn. His strategy will prove correct if he can also play b6-b5, but Hort puts an end to that idea. } 14. a4 Bc6 { A full question mark for this positional blunder. The advance b6-b5 has become an idee fixe for Karpov, notwithstanding Hort's anticipation. While Black has eyes only for the queenside, Hort has not forgotten about the center! } 15. Ne5 { White can occupy this outpost since the base of Black's pawn chain at d5 is without sufficient support. If Black captures at e5, he loses a pawn. But as things stand, White threatens to remove an important defender. } 15... Qc7 { 15...Bb7 temporarily keeps the defense intact, but after } 16. Bf3 { the threat f Ne5xc4 is quite real, and even after 16...Rac8, an eventual break with e3-e4 is inevitable.  Nxc6  Qxc6  Bf3  There is an immediate threat of 18.Nxd5 Nxd5 19.Bxe7!, exploiting the pin on the long diagonal. } 16... Bb4 { This move not only removes the threat at e7, but also creates the possibility of eliminating the Nc3 which is putting pressure on d5. But Hort realizes that the pin can be effective immediately. } 17. Nxd5 Nxd5 18. Qf5 { White regains his material, since 19...N7f6 is met by 20.Bxf6 and the Nd5 falls.  Qxa4  Bxd5 } 18... Rac8 { Karpov should have defended along his second rank with 20...Ra7, but he must have overlooked White's next move. } 19. b3 { Hort found this move because he was examining positions with the Rf8 moved off the f-file. This move opens the c-file, and forces the Rf8 to move. } 19... cxb3 { 21...Qb5 22.bxc4 Qa4 23.Ra1 and the Nd7 is dead.  Rxc8  Rxc8 } 20. Qxf7+ Kh8 { Bxb3  Qb5  Be6  and the pin wins!  Rf8  Bxd7!  Karpov resigned, since after 26...Rxf7 27.Bxb5 axb5 28.Rb1 his endgame is lost, while 26...Qe2 is met by 27.Qb3. } 1-0

1. d4 Nf6 2. c4 g6 { Somehow I always keep putting the King's Indian aside and then come back to it at critical times in my career. } 3. Nc3 Bg7 4. e4 d6 5. Be2 O-O 6. Bg5 { This system, named for Yuri Averbakh, has never caused me much concern. } 6... c5 7. d5 b5 { This sacrifice is similar to that of the Benko Gambit. It is not the best move, speaking objectively, but when I want to introduce complications it serves the purpose well. } 8. cxb5 a6 9. a4 { I know this is the best move. I played it as White against Spassky the same year. But as Black I had a better reply prepared. } 9... h6 { Before reacting in the center I wanted to drive the bishop back. } 10.

Nxb5 d5 { An important moves which opens up the center. The delayed advance of the pawn is typical of hypermodern play. } 17. exd5 Nxd5 18. Ne5 { A good move. The threat is Nxg6, because if I capture the knight then my bishop on e6 is loose. } 18... Re8 19. Rc1 { A natural move, but it leads to disaster. I am employing the equivalent of a "full court press" in basketball, keeping up the pressure all over the board. I must keep the initiative at all costs. } 19... Bf5 { Now the knight at e5 is under attack. Should it advance or retreat? } 20. Nc6 { 20.Nc4 Rxe1+ 21.Bxe1 Nf4 22.Qxd8+ Rxd8 I would have control of the important d-file. } 20... Qd7 { This sacrifices a second pawn. But keep your eye on the c5-square, it plays a very important role from here on! } 21. Rxc5 Rxe1+ 22. Qxe1 { 22.Bxe1 Re8 The back rank is very weak, and I threaten Nf4! } 22... Re8 23. Qc1 Nb6 { I must keep attacking. If my opponent gets time to breathe my attack will end and those queenside pawns will race down the board and kill me. } 24. b3 Re2 25. Ba5 { Everything seems under control. As it turns out this is an error, which allows me to create new threats. 25.Bc3 Rc2 26.Qe1 Be4 This would have been a very messy position. } 25... Be4 26. Ne5 Qe7 { Now Tukmak ov had to play 27.Qe1 which would have led to a very messy position. I have no idea how the game would have turned out. But fortunately for me he made a mistake. } 27.

1. d4 Nf6 2. c4 e6 3. Nf3 b6 4. a3 { My favorite variation during the 1980's was this old and forgotten line which Petrosian used to play. Now it is considered one of the main lines of the Queen's Indian Defense! } 4... Bb7 5. Nc3 Ne4 { Until this game, the violation of the opening principle which says never to move a piece twice without good reason was considered acceptable in this position. But after the game, it disappeared from the tournament arena. } 6. Nxe4 Bxe4 7. Nd2 Bg6 { The bishop has switched sides of the board. It was more common to retreat back to b7. } 8. g3 { Since Black has abandoned the long diagonal, it makes sense for White to take it over for himself. } 8... Nc6 { This square would have been better occupied by a pawn. } 9. e3 a6 10. b4 { I am taking control of a lot of territory on the queenside, so my Swedish opponent chooses to take some action there. } 10... b5 11. cxb5 axb5 { Now there is a trap. Suppose I capture on b5. Do you see what Andersson had in mind? } 12. Bb2 Na7 { A very subtle move, typical of the style which has kept Andersson among the world's elite for two decades already. The idea is to play d7-d5, and then bring the knight to c4 via c8 and b6! Wonderful! } 13. h4 { But while all that is going on, I have my sights set on the kingside. } 13... h6 { Just a little weakness, but it gets the creative juices flowing. } 14. d5 { Who cares about a little pawn? I want my bishop in the game. } 14... exd5 15. Bg2 c6 16. O-O { My advantage has grown. I have a big lead in development and control a lot of space -- just the kind of position I love! Now I just have to smash open the kingside with e2-e4. But not yet, let's get some more pieces involved. } 16... f6 17. Re1 Be7 18. Qg4 Kf7 { Well, if the king occupies this square then the bishop cannot, so it is time to push it into the corner. } 19. h5 Bh7 20. e4 { Now! } 20... dxe4 21. Bxe4 Bxe4 22.

Nc8 { 22...Rf8 23.Rad1 d5 24.Nxf6 Bxf6 25.Qe6++ 22...Re8 23.Qg6+ Kf8 24. g4 and I can bring my knight to f5 via g3. } 23. Rad1 { This is a strong move. To attack successfully means getting all the pieces involved in the attack. This rook will soon be on g4, believe it or not! } 23... Ra7 { Black wants to move the d-pawn and use the rook at a7 to help defend the king. So I had better get the attack moving quickly. Now comes a series of sacrifices. } 24.

1. c4 b6 2. d4 Bb7 3. Nc3 e6 4. e4 Bb4 5. Bd3 f5 { White has grabbed a lot of space, but given Black a target in the process. Black last move sharpens things up a lot. Since White can't play 6.exf5 Bxg2 7.Qh5+ Kf8, he has to leave e4 as a target. } 6. Qh5+ g6 7. Qe2 Nf6 8. f3 Nc6 9. e5 { The losing move. White has committed to a big center and was feeling the heat, but now the tactics explode in his face. 10.Be3 f4 would be fine for Black, so White would've done better with a more modest buildup. } 9...

Rxd1 fxe5 { This isola ted pawn, which can no longer be defended by a pawn on either side, is very weak. } 9. Rd3 Bd6 10. Nbd2 Nf6 11.
