Nc6 { This is the classical treatment of the King's Indian Defense. White maintains the broad center, which will eventually become closed. Then it will become a battle on both flanks. } 8. d5 Ne7 9. Ne1 { This retreat is well-established, but the alternative 9.Nd2 is also popular. In either case White needs to regroup on the kingside, and find a home for the dark-squared bishop. } 9... Nd7 10. Be3 f5 { Here we go. Black is going straight after the enemy king. If the plan does not succeed then White will have a free hand on the queenside. } 11. f3 f4 12. Bf2 g5 13. b4 { White has many other possibilities, but this is the most direct move. Still, there is much to be said for 13.Nb5. } 13... Nf6 14. c5 Ng6 15. cxd6 cxd6 { White has opened the c-file and will now occupy it. } 16. Rc1 Rf7 { This guards the critical f7-square. } 17. a4 Bf8 { A good move, because d6 will need support, and in any event the bishop is no longer very useful at g7, because it is blocked in by the pawn wedge. } 18. a5 Bd7 19. Nb5 { See how useful Bf8 turned out to be! White should perhaps have attended to the safety of the king with 19.Kh1. } 19... g4 { Black can't afford to waste any time. } 20. Nc7 g3 21. Nxa8 { Perhaps this is the decisive mistake. After 21.hxg3 the position would be very complicated, but there is no immediate win. Here is one suggested line . 21.hxg3 fxg3 22.Bxg3 Bh6 23.Nxa8 Nh5 24.Bf2 Ngf4 25.Nd3 Rg7 26.Nxf4 Bxf4 27.g4 Bxc1 28.Qxc1 Nf4 29.Qe3 h5 30.Rc1 hxg4 31.fxg4 Nxe2+ } 21... Nh5 { By resisting the temptation to advance the h-pawn, I managed to keep this square free for the knight. } 22. Kh1 gxf2 23. Rxf2 Ng3+ 24. Kg1 Qxa8 25. Bc4 { Now how do I continue the attack? I need to involve my queen somehow. } 25... a6 { Aha! I can use it on the a7-g1 diagonal. } 26. Qd3 Qa7 27. b5 axb5 28. Bxb5 { Now for the kill! Do you see the move? } 28... Nh1 29. Kxh1 Qxf2 30.

Bg5 c5 6. e3 cxd4 7. exd4 d5 { The Opening has transposed to a variation of the Panov-Botvinnik attack from the Caro-Kann Defense. } 8. cxd5 Nxd5 { White excepts the isolated d-pawn in exchange for active piece play. } 9. Qb3 Nxc3 { 9...Nb6 would keep pressure on the isolated d-pawn at the expense of moving the knight for the third time. } 10. bxc3 Nc6 11. Be2 b6 12. O-O Qd6 { This commits Black's queen too early. 12...Bb7 would have been better. } 13. Rad1 e6 14. Nd2 Na5 { 14...Bb7 15.Ne4 Qd7 16.Nf6+ Bxf6 17.Bxf6 would be better for White due to the dark square weaknesses around Black's king . } 15. Qb4 Qc7 { 15...Qxb4 16.cxb4 Nc6 With pressure against the isolated d-pawn was better. } 16. Ne4 h6 17. Qe7 { With this intermediate move White is able to gain the bishop pair. } 17... Qxe7 18. Bxe7 Re8 19. Nf6+ { Now the position without queens will favor White, who has the bishop pair. } 19... Bxf6 20. Bxf6 Bb7 21. Rd3 { Played with the idea of attacking on the h-file after a future Rh3. } 21... Bd5 22. Rh3 Kh7 23. Re1 e5 { 23...h5 24.g4 would win a pawn while keeping a powerful attack on the h- file. } 24. dxe5 Nc4 25. Bxc4 Bxc4 { Black resigned before White could play a winning combination. Do you see it? If not, Gambit can demonstrate it for you if you set Gambit up as White.. } 1-0

Karpov should have completed his development now with 22...Rc8, but instead he panics and releases the tension in the center. } 22... fxe4 { 22...Rc8 23.Rf3 fxe4 24.Nxe4 A very messy position with unclear complications. } 23.

Qxa4 { Black has gotten rid of the famous "Spanish bishop", but aside from that he hasn't done much. My pieces occupy better squares. He has no good squares under control, so now he takes over b4 for his knight. } 16... a5 17. Bd2 Re8 18. d5 Nb4 19. Bxb4 { So much for the big square!

A typical hypermodern strategy. } 10. c5 { This is an interesting move, attempting to derail Black's strategy. 10.d5 used to be the main line, but it is no longer considered strong. } 10... dxc5 11. dxe5 Ne8 12. Na4 Qa6 13. Bf4 { Both 13.Bg5 and 13.Qc2 are interesting alternatives. } 13... Nc7 14. Qc2 Ne6 15. Rfd1 Re8 16. Rd6 { 16.Nc3 might have been better, planning to swing the knight to e2. Now I take control of the middlegame, making significant progress on the queenside. } 16... Qa5 17. Rad1 Nb6 18. Nxb6 axb6 19. a3 Qa4 20. Qe2 { 20.Qd2 Qxe4 Now White can win the queen but still winds up with a bad game. 21.

Bc2 exd4 14. cxd4 { Having exchanged at d4, Black can now attack my bishop at c2. } 14... Nb4 15. Bb1 bxa4 { This is an important position.

The d-pawn can advance and then the rook helps protect the kingside. } 18. Nh2 g6 19. f3 { This was my prepared innovation. All of a sudden this position looks very bad for Black, whose pieces are uncoordinated. } 19... Qd7 20. Nc4 Qb5 21. Rc3 Bc8 { Probably an error. Advancing the d-pawn was best, but does not solve all of the problems. 21...d5 22.Na3 Qb6 23.e5 Nd7 24.f4 c5 25.Be3 } 22. Be3 Kh7 23. Qc1 c6 { This is a b ad move, because it defeats the purpose of placing the rook at a6. Now it can play no role on the kingside. Better was 23...Qd8. } 24.

This is what the "experts" thought I missed. But I knew what I was doing. Black's pieces are scattered and cannot work together. That there are more of them is not the point. } 30. Rd1 Qxe8 31. Qg5 Ra7 { 31...Ng8 32.Qh4+ Kg7 33.Rd8 Qe6 34.f4 Black has a two knights for a rook and a pawn, but can't possibly survive. } 32. Rd8 Qe6 33. f4 Ba6 34. f5 Qe7 35. Qd2 Qe5 36. Qf2 Qe7 37.

Rb8 { 15...Nxb6 16.Qxb4 d5 17.Qxb6 Qxb6 18.Bxb6 dxe4 19.Rd7! wins for White. } 16. Nxd7 Qxd7 17. Kb1 { White has the superior position because of a spatial advantage and prospects for a kingside attack. } 17... Qc7 18. Bd3 Bc8 19. h5 e5 20. Be3 Be6 { Spassky could have reached a similar position some time ago, with less danger to himself on the kingside. Now Fischer quickly builds his attack. } 21. Rdg1 a5 22. g6 { A typical example of the g6-break, seen many times in the games of Mikhail Tal. } 22... Bf6 { Relatively best, since any capture at g6 could prove deadly. } 23. gxh7+ Kh8 24. Bg5 { White eliminates Black's most effective defender. } 24... Qe7 { 24...Bxg5 25.Rxg5 f6 would have provided stiffer resistance, though White would still have had an impressive attack. } 25. Rg3 { White wants to double rooks on the g-file. } 25... Bxg5 26. Rxg5 Qf6 { 26...f6! would have been a stronger defense. } 27. Rhg1 Qxf3 { Otherwise Wh ite will play his queen to g2 with an overpowering attack. Now Fischer must work for the win. } 28. Rxg7 Qf6 29. h6 { A problem-like solution. White must sacrifice both h-pawns to expose the enemy king to the mating attack. } 29... a4 30. b3 { A prophylactic move to eliminate any counterplay. } 30... axb3 31. axb3 Rfd8 { Black tries to play d5, and get something going. } 32. Qg2 Rf8 33. Rg8+ Kxh7 34. Rg7+ Kh8 35. h7 { Since Rg8+ followed by a check on the h-file is inevitable, Black resigned. Score: Fischer 9, Spassky 4, 12 draws. } 1-0

Timman had seen some analysts claim that it was better than 12...b6. But in an old book by Boyd it had already been criticized. } 13. b4 { A somewhat risky move, but as Timman wrote "White should not have stifled his urge for expansion". } 13... Nd7 14. cxb5 { Timman spent more than 40 minutes on this move. In the old Boyd book, the c- pawn was advanced rather than exchanged. 14.c5 a5 15.c6 axb4 16.Nxb5 Nc5 17.Qxb4 Rxa2 The position is complicated, and much to my liking. 14.exf5 gxf5 15.Ng3 Nf4 Now if White captures at f4, then I would recapture with the pawn and open up the diagonal for my bishop. } 14... axb5 15. Nxb5 { This was actually the first new move of the game. Some authorities think that 15.Kb2 would have given White a clear advantage, but this is an opinion that neither I nor Jan Timman would agree with. 15.Kb2 Nb6 So what is wrong with Black's position? Surely it is too dangerous to capture the b-pawn. } 15... Rxa2 16. Nec3 Ra8 17. Kb2 { A consistent move which plans to bring the rooks to the a-file. Some critics think that White should have sunk his knight into a7, headed for c6. Timman does that at his next turn. } 17... Ndf6 18. Na7 { 18.Ra1!? Rb8 } 18... fxe4 19.

Maybe I would have been worse! 23.Kb3 Qxc6 24.Ne7+ Kh8 25.Nxc6 Be6+ I would have loved to have had a chance to play this at the board! } 23... exd3 { Now we shall see that the bishop at g7, which has been asleep for most of the game, wakes up just in time to help deliver the final blow. The long diagonal is a tremendous weapon for Black in the King's Indian Defense! } 24. Nce7+ { I wished he had played his king up to b3.

1. e4 c5 { After the disaster of the previous Spanish Inquisition, Spassky slides into Sicilian territory. } 2. Nf3 Nc6 3. Bb5 { Somewhat of a surprise. Fischer usually prefers the well-traveled paths of more topical lines, enjoying the theoretical duels. } 3... g6 4. Bxc6 bxc6 { Theory prefers 4...dxc6, but there is nothing wrong with this choice. } 5. O-O Bg7 6. Re1 e5 { A critical advance, which prevents White from playing e4-e5 or d2-d4. But the blocking of the long diagonal creates an interesting opportunity for White. Spassky consistently rejects previous praxis, but opts for 6...f6 in game 13. } 7. b4 { A typical example of a move which is trivial when played prematurely (at move 2) but which can be quite effective if delayed until an appropriate moment. } 7... cxb4 8. a3 { This gambit underlines the defects of 6...e5. } 8... c5 { 8...d6 9.axb4 Ne7 10. h3 O-O 11.d3 gives White a slightly better position, because there are some weaknesses in Black's position.
