GM Hikaru Nakamura (USA)-GM Loek Van Wely (Netherlands), Wijk aan Zee 2010: 1 e4 c5 2 Nf3 d6 3 d4 cxd4 4 Nxd4 Nf6 5 Nc3 a6 6 Bg5 The sharpest treatment of the Najdorf Sicilian. e6 7 f4 Nbd7 Black keeps more options by delaying . . . Bf8-e7. 8 Qf3 Qc7 9 Bxf6 Nxf6 10 g4 b5 11 g5 Nd7 12 0-0-0 Welcoming the old main line, 12 . . . Be7 13 f5. Nc5 Reasonable, and less investigated. Too dangerous is 12 . . . b4?! 13 Nd5! exd5 14 exd5, while 12 . . . Bb7 13 Bh3 Rc8 14 Rhe1 leaves e6 vulnerable to a sacrifice or to f4-f5. 13 a3 The hasty 13 f5?! b4 favors Black. Rb8 14 b4 New. Nd7 After 14 . . . Na4 15 Ndxb5! axb5 16 Bxb5+ Rxb5 17 Nxb5 Qb6 18 Qd3 Bd7 19 Nxd6+ Bxd6, the finesse 20 Rd2! avoids 20 Qxd6? Qe3+ and recovers material advantageously. 15 Nd5! A promising version of a standard sacrifice. exd5 Declining doesn't help, as 15 . . . Qb7 16 Qc3 forces 16 . . . exd5 17 exd5 Nb6 18 Re1+ Be7 19 Nc6 Nxd5 20 Qxg7. Then 20 . . . Rf8 21 Nxe7 Nxe7 22 Bd3 leaves Black helpless against f4-f5-f6. 16 exd5 Be7 Black will return material to castle. However, 16 . . . Bb7 17 Qe3+ Kd8 18 Bg2 appears best. Then 18 . . . Be7 19 Rhe1 Re8 20 Nf5 Rc8 21 Re2 Qc3! 22 Qxc3 Rxc3 23 Rde1 Rxa3 gives Black adequate counterplay. 17 Re1 Ne5 The other plausible defense, 17 . . . Nb6 18 Nc6 Nxd5 19 Qxd5 Be6, lets White attack with 20 Nxe7 Qxe7 21 Qd2 g6 22 h4. 18 fxe5 Bxg5+ 19 Kb1 dxe5 20 Nc6 Bf6 21 Bd3 Correctly preferring the initiative to material gain by 21 Nxb8 Qxb8 22 Bd3 Qd6, when White cannot easily break through. h5? Sturdier is 21 . . . Rb6, setting the trap 22 Nxe5?? Bxe5 23 Qh5 g5! 24 Qxg5 f6. But it's difficult to find a move for Black after 21 . . . Rb6 22 Rhf1 Bb7 23 Be4, because 23 . . . Bxc6 24 dxc6 would let White bring a Rook to d7. 22 Rxe5+! Bxe5 23 Re1 Bg4 24 Qf4 0-0 White refutes 24 . . . f6 precisely by 25 Bg6+! Kd7 26 Bf5+!

Tougher is 25 . . . f5 26 Nxb8 Qxb8, although 27 Qd4, threatening 28 Re7 and 28 d6, is irresistible. 26 Qf6 Rbe8 27 Ne7+ Rxe7 Or 27 . . . Kh7 28 Bxg6+, mating. 28 Rxe7 Qxh2 29 Bxg6 Qh1+ 30 Kb2 Qxd5 31 Bxf7+ Simplifying to an easy endgame. White could win in the middlegame by 31 Be4 Qd2 32 Bd3!, with the unstoppable threat of Re7-e5-g5. Qxf7 As 31 . . . Rxf7 permits 32 Re8+. 32 Rxf7 Rxf7 33 Qxa6 Kg7 34 Qxb5 Kg6 35 Qc4 Rd7 36 b5 Kg5 37 b6 Bf3 38 Qb5+ Rd5 39 Qb3, Black Resigns.
