Shirov,A (2737) - Kasparov,G (2830) [B90]
Linares (1), 19.02.2004
[Mikhail Golubev]

The titanic tactical struggle between Shirov and Kasparov turned into the highlight of the first round. 1.e4 c5 2.Nf3 d6 3.d4 cxd4 4.Nxd4 Nf6 5.Nc3 a6 6.Be3 e5 7.Nb3 Be6 8.f3 Nbd7 9.Qd2 b5 10.a4 b4 11.Nd5 Bxd5 12.exd5 Nb6 13.Bxb6 Qxb6 14.a5 Qb7 15.Bc4

This is a really popular setup in the Sicilian Najdorf: every year brings us new games of the highest level... White's idea is to win the weak b4 pawn and then either to crush Black's queenside completely, or simply to consolidate his advantage. Black's plan is to create dynamic play against the white king. 15...g6! Kasparov's move, which he introduced in 2000 in a rapid game against Shirov! [ Earlier Black tried 15...Be7 ] 16.Ra4 Rb8 17.Qd3 Ra8 18.Qd2 Rb8

19.Nc1 Alexei shows "who is the boss" and plays on. [ Three and half years ago he took a draw by repetition, which Black is not able to avoid: 19.Qd3 Ra8 1/2-1/2 Shirov-Kasparov, Frankfurt rapid 2000.] 19...h5 20.Nd3 [ More often White preferred 20.Na2 . The last word there was 20...Bh6 21.Qe2 Qd7!? ( 21...0-0) 22.b3 0-0 23.0-0 e4 Anand-Topalov, Corsica rapid 2003 (CT-1093).] 20...Bh6 21.Qe2 [ After 21.Qxb4 Qc7 22.Qa3 0-0 23.Nf2 Bc1 24.Nd3 (Polgar-Shirov, Linares 2001) Black could have repeated position by 24...Bh6!?=] 21...0-0 22.Nxb4

With transposition of moves, the opponents have reached a position which earlier occurred via 18.Na2 move order. Now Kasparov finally deviates from the previous games: 22...Qd7N [ 22...e4 23.0-0 Qd7!? 24.Nc6 Rxb2 25.fxe4 Ng4 with certain compensation for Black occurred in Gelfand-Topalov, Rapid Wch 2003 (CT-1085).] 23.Nc6!? [ Who knows, what Kasparov prepared against the natural 23.b3 . Possibly he would sacrifice a queen by 23...Qxa4!? ( 23...e4 is another option) 24.bxa4 Rxb4 25.Bb3 Ra8 26.0-0 Nd7 followed by 27...Nc5.] 23...Rxb2 24.0-0 The material is balanced now, but even here Black must play for maximum activity. His a6 pawn and also rook on b2 are in danger. 24...h4!? Kasparov plans ...h3, or maybe ...Nh5-f4, preserving the idea of ...e5-e4 as well. [ An immediate 24...e4 would transpose to Gelfand-Topalov game.] 25.Bb3 [ 25.Qd3 was one of alternatives. Then curious, (even if incorrect?) is 25...e4!? 26.Qc3 exf3 27.h3 ( 27.gxf3 Qh3!) 27...Qe8 28.Ra3 Nh5 ( 28...Qe4? 29.Qxb2 Be3+ 30.Rxe3 Qxe3+ 31.Rf2!) 29.Qxb2 Be3+ 30.Rf2 Nf4!] 25...h3 26.g3 Shirov doesn't like to have too many weaknesses on the his kingside. 26...e4

Black's play may look doubtful, but it's not easy to refute it. White's king is an almost permanent problem. 27.fxe4 [ 27.f4!? makes sense, but is not too clear as well.] 27...Qg4!? Kasparov uses the opportunity to activate his queen. [ After 27...Ng4 White could have tried to find something stronger than 28.e5 Be3+ 29.Kh1 Nf2+ 30.Kg1 Nd1+ with a draw.] 28.Qd3 [ After 28.Qxg4 Be3+! 29.Kh1 Nxg4 Black is out of danger.] 28...Qg5 29.e5

As result of this sacrifice, White gets an advanced pawn and opens the way to the kingside for his rook. [ In case of 29.Kh1 Nd7! with the idea 30...Nc5 he could face problems.] 29...dxe5 30.Rh4!? [ After 30.d6 e4 31.Qd4 Qe3+! 32.Qxe3 Bxe3+ 33.Kh1 Ng4 34.Raa1 Nf2+ 35.Rxf2 Bxf2 an unclear endgame arises. White must continue with 36.Rc1 in order to meet 36...e3 with 37.Bc4.] 30...e4! [ Worse 30...Nd7 31.Kh1!? with idea 31...Nc5 32.Qf3 Nxb3 33.cxb3 Qd2 34.Rxh3] 31.Qd4 Ng4!?

[ 31...Qe3+ 32.Qxe3 Bxe3+ 33.Kh1 Bd2! would also have led to quite a messy situation.] 32.Rxh6 It's not easy to find anything better among the alternatives: [ 32.Ne7+ Kh7! and, amazingly, the line 33.Qxe4? ( 33.Re1!?) 33...Qxh4!! 34.Rxf7+ ( 34.gxh4 Be3+ 35.Kh1? Nf2+ 36.Rxf2 Rb1+) 34...Kh8! 35.Nxg6+ Kg8 36.d6 Rb1+ 37.Rf1+ Kg7 38.Rxb1 Qg5 is winning for Black.; Immediate 32.Re1? fails to 32...Qe3+!; 32.Rxh3 Qe3+ 33.Qxe3 Bxe3+ looks not bad for Black; Finally, 32.Kh1 Bg7!? 33.Qd2 e3 ( 33...Qxd2? 34.Ne7#) 34.Qe2 ( 34.Qb4? e2 35.Re1 Re8 36.Rxg4 Qe3!) 34...Rxb3 35.cxb3 Qxd5+ 36.Kg1 Qxc6 37.Rxg4 Rd8 38.Rc4 Qb7 is rather in Black's favour] 32...Nxh6!

[ Not 32...Qxh6? 33.d6!+/- Ne3 34.Ne7+ Kh7 35.Bxf7 Rxc2 36.Bxg6+ Qxg6 37.Rxf8 Rc1+ 38.Kf2 Nd1+ 39.Qxd1 , and doesn't work 39...e3+? 40.Kf3! Qh5+ 41.g4!] 33.Qxb2 Shirov decides to finish the fight, and goes for a clear draw. Probably a justified decision. [ After 33.d6 Black has 33...Nf5!] 33...Qe3+ 34.Rf2 [ Not 34.Kh1?? Qe2-+] 34...Qe1+ [ If 34...Ng4 , White can force draw by 35.Qd4 ( 35.c3!?) 35...Qe1+ 36.Rf1 Qe2 37.Rf2] 35.Rf1 Qe3+ A game of incredible complexity. My analysis certainly will be improved by other annotators, but most intriguing would be to hear, at which point Kasparov and Shirov were out of their home preparation! 1/2-1/2
