World Cup 2007 Live: Game 4 : Shirov Do Or Die!

GM_Kamsky (2714) - *GM_Shirov (2739)

World Cup 2007 Final. Game 4. 16.12.2007

1.e4 c5 2.Nf3 Nc6 3.Bb5 The Rossolimo Variation, 3.Bb5 is a well-respected alternative to 3.d4. White's usual intention is to play Bxc6, giving Black doubled pawns. Black's major responses . In Game 2 Kamsky choose 3. Nc3 and won the game. 3.Nc3 is a common transpose strategy for White, who can choose 4.d4 or 4.Bb5 next move depending on Black's response. Black usually plays 3...e5 to avoid both moves; White usual response is 4.Bc4 . 3.c3 goes into the lines of the Alapin Variation after 3...Nf6 or 3...d5. 3…g6 preparing ...Bg7, 4.0–0 Bg7 5.c3 Nf6 6.Re1 0–0 7.d4 d5 8.e5 Ne4 9.Bxc6 bxc6 10.Nbd2 Bf5 11.Nh4 e6 12.Nxf5 exf5 13.f3 [ Fritz Opening books end here. It give 13.Nf1 Rb8 14.Re2 (14.f3 Ng5 15.dxc5 Ne6 16.b4 Qc7 17.f4 d4 18.Qf3 a5 19.a3 dxc3) 14...Re8 15.Qa4 cxd4 16.cxd4 c5 17.f3 cxd4 18.fxe4 dxe4 19.Qxa7 Bxe5; 13.Nf3 Rb8 14.Re2 Re8 15.Ne1 cxd4 16.cxd4 c5] 13...cxd4 (13...Nxd2 will lead into a dry simplified game. It will increase Kamsky chance to reach equal position-something Shirov will try to avoid at any cost!) 14.cxd4 [14.fxe4 will lead into a strong initiative for black. 14...dxc3 15.bxc3 fxe4 16.Ba3 Re8 17.Bd6 Qb6+ 18.Kh1 Bxe5 19.Bxe5 Rxe5 Black connected pawn formation in the center look dangerous.] 14...Ng5 15.b4 a5?! didn't like this move because it gave white a passed pawn on a file without any real compensation. may be better.16.bxa5 Rxa5 17.Nb3 Ra7 18.Bxg5?! According to Kamsky second-Emil Sutovsky, this move is incorrect.The correct plan should be placing a pawn on a4 and play Nc5-Ne6. Qxg5 19.Qc2 Rc8 20.a4 Here come the passed pawn! 20...Bf8 21.a5 Bb4 22.Re2 Qd8 Now Shirov have too spend his time defending against the advance of white a pawn. 23.e6 [23.Qc1!? Bxa5? 24.Rea2 Rca8 25.Qxc6] 23...fxe6 [23...Bxa5?? taking the pawn is naive 24.Rxa5 (24.Nxa5?! Rxa5 25.Rxa5 Qxa5=) 24...Re7 (24...Rxa5 25.e7 Qe8 26.Nxa5) 25.exf7+ Kxf7 26.Ra1+-] 24.Rxe6 Qd7 25.Qe2 (25.Nc5 Qg7 26.Nb3 Qd7=) 25...Kf7 26.Re5 Bd6 27.f4!? A move that was not consider at all by Fritz. Of course this positional sacrifice is "beyond" any computer knowledge. Black knight will be heading to a strong outpost at c5 as a compensation of his rook sacrifice. 27...Bxe5?! Shirov regret playing this move. He later mentioned that he should have played 27...Qb7 instead. 28.fxe5 Qb7 29.Nc5 Qb4 30.e6+ Kg8 31.Rd1 Qxa5 32.e7 Re8 33.Qe6+ Kg7 34.Qe5+ Kf7 35.Qe6+ 1/2-1/2 35...Kg7 36.Qe5+ Kh6 ??37.Ne6 Raxe7 38.Qf4+ g5 39.Qxg5# Shirov can't do much. White has many chooise to draw the game. Congratulation Kamsky. You are the World Cup 2007 Champion!!!
