GM Eduardo Iturrizaga (Venezuela)-IM Vasily Papin (Russia), Aeroflot Open, Moscow 2010: 1 c4 e6 2 Nf3 Nf6 3 d4 d5 4 e3 Capablanca used this form of the Queen's Gambit a century ago. Much more common is 4 Nc3 Be7 5 Bg5. a6 5 b3 c5 The approved counter, but Black does not fully equalize. 6 Nbd2 Nc6 7 Bb2 cxd4 Also 7 . . . b6 and 7 . . . Be7 are reasonable. 8 exd4 b6 9 Bd3 Bb7 10 0-0 Be7 11 Qe2 0-0 12 Rac1 Re8 The sharper 12 . . . dxc4 13 bxc4 b5!? probably favors White after 14 Rfd1 bxc4 15 Nxc4. 13 Rfd1 Qb8?! Black should continue solidly with 13 . . . Bf8 14 Qe3 g6 15 Ne5 Rc8. 14 Ne5 Welcoming 14 . . . Nxe5 15 dxe5 Nd7 16 cxd5 Bxd5, as 17 Be4 lets White operate on the c- and d-files. However, this was a safer course for Black than the game. dxc4 15 Ndxc4! White gets nothing from 15 bxc4?! Nxe5 16 dxe5 Nd7. Qa7? Losing. Black must try 15 . . . Nxe5 16 dxe5 Nd5 or the computer's suggestion 15 . . . Qd8 16 Nxf7!? Kxf7 17 Ne5+ Nxe5 18 dxe5 Qd5! 19 f3 Nh5 20 Be4 Qb5, with chances to survive. 16 Nxf7! Kxf7 17 Ne5+ White will recover the piece or roust Black's King from its fortress. Nxe5 18 dxe5 Nd5 No better is 18 . . . Ng8 19 Qh5+ Kf8 20 Rc4! Nh6 21 Bxh7, followed by 22 Rf4+. The attempt to return material by 18 . . . g6 19 exf6 Bxf6 loses instantly to 20 Rc7+ Re7 21 Bc4! Rxc7 22 Qxe6+. 19 Qh5+ Kf8 20 Qxh7 Bc5 The prettiest refutation of 20 . . . Bg5 is 21 Rc7! Nxc7 22 Ba3+ Be7 23 Bg6, preparing 24 Qh8 mate. 21 Bg6 Rec8 22 Qh8+ Ke7 23 Qxg7+ Kd8 24 Rxc5! Removing the guard so White can use f8 and d6. Rxc5 25 Qf8+ Kc7 26 Qd6+ Kc8 27 Bf7 Bc6 Black would be completely helpless after 27 . . . Rc7 28 Bxe6+ Kb8 29 Rc1. 28 Bxe6+ Kb7 29 Rxd5 Qb8 30 Rxc5 Qxd6 31 exd6 bxc5 32 Bf6 Re8 33 Be7, Black Resigns. Next the f-pawn advances.
