1.d4 Nf6 2.c4 g6 3.Nc3 Bg7 4.e4 d6 The King's Indian defense. I played it four times in this tournament. I was aware of the risks, but of the odds as well. Two of these games were drawn, one was won by forfeit and this is the fourth, which I could win. Therefore, the choice was lucky this time. 5.Nf3 0-0 6.Be2 e5 7.0-0 Nc6 8.d5 Ne7 9.Nd2 Here is the main crossroad. There are two main alternatives: 9.Ne1 and 9.b4. 9...a5 10.a3 Nd7 Often played. [10...Bd7 is an alternative plan, rather popular nowadays with a different plan: play in the centre and on the queen's side with c6. Perhaps it is more solid than the classic set-up with the knight in d7, but I consider this as a premature resignation of the classic spirit of the King's Indian.] 11.Rb1 f5 12.b4 Kh8 A little bit sophisticated. Before Black can close the position by f4 and launch the king side attack, he waits until White plays f3. The time is used to bring the king to a safer place and to free the square g8 for the knight. 13.f3 [13.Qc2 Ng8 14.f3 Ngf6 15.Bd3 leads to the game.] 13...Ng8 [13...axb4 (followed by c6) is an important alternative played by high-rated players like Nakamura or Radjabov.] 14.Qc2 Ngf6 15.Bd3 Joe Gallagher gave a ! to this move in his good book about King's Indian and wrote "...has proved quite difficult for black". I think that things are not so simple. 15...f4 16.Nb5 b6 17.Bb2 [17.c5!? is an interesting pawn sacrifice that has been played in some important games as Ivanchuk - Kasparov, Linares 1992. But it is not popular nowadays.] 17...Ne8 18.Nb3?! [Better is probably 18.Be2 which is also played more frequently. Black usually replies 18...h5 going on with the standard pawn attack. But, perhaps, Black could continue with a similar plan as in this game.] 18...a4! A pawn sacrifice in exchange for three tempos that Black want to use for its attack on the kingside. The key for Black is to delay the thematic pawn break-through c5. 19.Nd2 Qh4!? The begining of an original plan. When I played this move the first time, I found only one game in my databases, and this was won by White. But I had a new idea. 20.Nc3 g5 21.Nxa4 Rf6!N See the diagram.

I applied this idea already before, at the Candidates' stage of the same World Championship in a game with Schima. I was very lucky that seemingly Istvan didn't know that game. The main aim of the text is to put queen and rook on the h-file trying to provoke a weakening as, say h3, when Black threatens to sacrify the bishop c8. Moreover, the rook is very useful for defending the third rank, whereas the knight on d7 defends the important square c5 for now. [Too slow is 21...Ndf6 22.c5 Bd7 23.Nc3 bxc5 24.bxc5 g4 25.Bb5 Bc8 26.Bc6 Rb8 27.a4 Rg8 28.Nc4 Bf8 29.Bxe8 Nxe8 30.Nb5 g3 31.h3 Rg5 32.Nxc7 Nxc7 33.cxd6 Kg8 34.Bxe5 Bxh3 35.Rxb8 Bd7 36.Rfb1 Rh5 37.Kf1 Qh1+ 38.Ke2 Qxg2+ 39.Kd3 Qxf3+ 40.Kd4 Ne8 41.R8b3 Qg4 42.Qd1 Qxd1+ 43.Rxd1 Bxa4 44.Ra1 1-0 Chenel,J-Chorfi,K/corr 1993] 22.Rf2! Istvan prepares to defend h2 with the knight, and thereby avoids to weaken his position by h3. Moreover, the rook is fine here defending the second rank and in some lines the king can even escapes via f1. [22.c5 is not good enough now, because the position looks rather unpleasent for White, see: 22...Rh6 A) 23.h3? Nxc5!! 24.bxc5 Bxh3! 25.Nc4 Bd7 26.cxb6 g4 threatening g3 and mate. 27.fxg4 only move 27...Nf6! (27...Qh2+ and Bxa4 must win, too, but the text is definitive) 28.b7 Rg8 (or 28...Rf8 ) 29.g3 (29.Be2 Qh2+ 30.Kf2 Qg3+ 31.Kg1 Rh2 32.Bf3 Qh4 33.g3 Qxg3+ losing the queen or 34.Bg2 Nxg4 and mate) 29...Qh1+ 30.Kf2 Qh2+ 31.Ke1 Qxg3+ 32.Kd1 Bxa4 33.Qxa4 Qxd3+ and wins easily.; B) 23.cxb6 23...g4 24.Qc6 Rb8 (24...g3 25.Rfe1!) White has achieved something on the queenside. On the other hand, Black is aiming to the White king and creates serious threats. I think Black is clearly better, maybe already winning. For instance 25.bxc7 There are other ways but not good enough either. 25...Rb7 26.Nb6 (26.Rbc1 Ndf6 27.b5 Rxc7-+) 26...Rxc7 27.Qb5 Qxh2+ 28.Kf2 g3+ 29.Ke1 Qxg2 30.Nxc8 Rh2 31.Rd1 Rc1 32.Be2 (32.Bxc1 Rh1 and mate) 32...Rxc8 33.Nb3 Nef6! 34.Qa6 (34.Qd3 Nb6 35.Qa6 Nxe4 36.fxe4 f3-+; 34.Rd2 Qh3 35.Qa6 Nb8 36.Qa7 g2-+) 34...Rc2 35.Rd2 Rxd2 36.Nxd2 Rh1 and the pawn g3 decides the game.] 22...Rh6 23.Nf1 [23.h3!? Despite the weakness, this might be a good defence, because f1 is free for the king's escape. With the rook on f2, this move is slightly more secure as before, since the second rank is defended. 23...Ndf6 The position is unclear. Among numerous possibilities I will show only one example of the possible complications. 24.c5 (24.Kf1!?) 24...Bxh3 25.Kf1 Nh5 26.gxh3 Ng3+ 27.Ke1 Nh1 28.Nc4 b5 (28...bxc5!?) 29.Nxd6 cxd6 30.Nb6 (30.Bxb5 Qg3! 31.Nb6 Rxh3 32.Rd1 Rh2 33.Rdd2 Rd8 followed by g4 and Black should win.) 30...Rb8 31.Bf1 Qg3 32.Bg2 Rxh3 33.Bxh3 Nxf2 34.Qxf2 Qxh3 35.Ke2 g4 36.Rg1 g3 37.Qf1 Qh2+ 38.Rg2 Qh3 remains unclear.] 23...g4 See the diagram.

24.fxg4? This will help me to transfer a knight to g4 strengthening the attack [In my older game with Schima 24.c5?! didn't work either, but it's a bit harder for Black 24...g3 25.Rd2 dxc5 26.bxc5 Bf8 27.Rc1 bxc5 28.Bb5 Nef6 29.Bc6 Ra7 30.Bb5 Bd6 31.Qb3 Ra8 32.Qc2 Qg5 33.Bd3 Rh5 34.Bb5 c4 35.Qxc4 Qh6 36.Qb3 Rxh2 37.Nxh2 Qxh2+ 38.Kf1 Rb8 39.Qd3 Rxb5 (ended: 10/8/2005) 0-1 Schima,W-Canovas Pordomingo,M.A./WC-2005-T-00002 2004; 24.g3!? This might be the only good alternative, though Black is able to go on with the attack after the g- and f-files will be open. 24...fxg3 25.Nxg3 gxf3 I have not studied deeply this position, but I prefer Black's side because of the attacking prospects and the initiative.] 24...Ndf6 25.g5 Qxg5 26.c5 The thematic advance appears too late. 26...Ng4! See the diagram.

27.cxb6 [27.Rd2 doesn't work either, see: 27...Qh4 28.g3 fxg3 29.Nc3 (29.cxb6 gxh2+ 30.Kh1 Rf6-+) 29...dxc5! 30.bxc5 Bf8 31.d6 gxh2+ 32.Kh1 Rf6 33.Rxh2 (33.Nd5 Nf2+ 34.Rxf2 Rxf2 35.Bxe5+ Bg7) 33...Nxh2 34.Qxh2 Rh6 (34...Bh3!?) 35.Qxh4 Rxh4+ 36.Kg2 bxc5 37.dxc7 Nxc7 With the material advantage, Black has a comfortable endgame.] 27...Nxh2!? [27...Nxf2 is also good.] 28.Nxh2 [28.Qc6 Qh5 29.Nd2 Ng4-+; 28.b7 It's better to deflect the bishop from the c8-h3 diagonal, but it is not good enough to save the game: 28...Bxb7 29.Nxh2 Qh4 30.Kf1 Qxh2 31.Ke2 Nf6 32.Kd2 (32.Qxc7 Qg3 33.Qb6 Ng4 34.Nc3 Rh2-+) 32...Rg6 33.Re1 (33.Rbf1 Ng4!) 33...f3! See the diagram.

Opens the diagonal h6-c1 to the bishop g7. 34.Rxf3 Rxg2+ 35.Be2 Rxa4 36.Qxa4 Bh6+ 37.Kd1 (37.Kd3 Qh4!) 37...Rxe2 38.Rxe2 Qh1+ 39.Kc2 Qxf3 40.Qb5 c6!-+] 28...Qh5 29.g4 [After 29.Kf1 Black would be able to continue like in the line 28.b7 above.] 29...fxg3 30.Rg2 gxh2+ 31.Kh1 [31.Rxh2 Qf3!] 31...Bh3 32.Rf1? [32.Rf2 Rg6 Threatens Qg4.; 32.Rg3 Qh4 33.Qxh2 Bd7 and wins the knight on a4.; 32.Bf1 Though this is better than the text, it should not be enough:. Black will get an exchange and the weakness of the white king is more important than the passed queenside pawns.] 32...Bxg2+ 33.Qxg2 Rg6 34.Qxh2 Qg4 35.b7 Rb8 36.Bc1 Nf6 37.Nc3 Nh5 38.Ne2 Bh6 The game ended on 20/6/2007. 0-1
