11....Be6 12.Re1 Be7 13.Qa4+ Nc6 (13....Bd7 14.Nxf6+ (14.Qb3 is even stronger) gxf6 15.Qb3 0-0 16.Bh6) 14.Nxe7 Qxe7 15.Ba3 Qd7 16.Rac1! (16.Bb5 also wins) 16....a6 17.Qb3 0-0-0 18.Bxe6 fxe6 19.Ne5 Qd5 20.Nxc6 bxc6 21.Qb6 11....Nxd5 12.Bxd5 Be7 13.Bxf7+! Kxf7 14.Ne5+ Ke8 15.Qh5+ g6 16.Nxg6 hxg6 17.Qxh8+ Bf8 18.Re1+ 11....Nc6 12.Ng5 Be6 13.Re1 Nxd5 14.Bxd5 Be7 and now either 15.Rxe6 fxe6 16.Nxe6 Qd7 17.Nxg7+ Kd8 18.Bf4 or 15.Nxe6 fxe6 16.Rxe6 Qd7 17.Rb1!
Position after 17.Rb1:
 click for larger view17.Qh5+ or 17.Bxc6 also win; note that after Rb1 White also threatens Rxb7!. But the very beautiful point of 17.Rb1 is revealed after 17....0-0-0: 18.Rxc6+! bxc6 19.Qb3 Qc7 20.Be6+ Rd7 21.Bf4! -- eat your heart out, Paul Morphy -- 21....Bd6 22.Bxd6 Qxd6 23.Qb7+! Kd8 24.Bxd7 Qxd7 25.Qb8+ Qc8 26.Qd6+. White still had the advantage after 11.Re1+ Be7 12.Ba3? (12.Nxd5 was again stronger) 12....Nc6? and now 13.Nd4!! would have been winning: 13....Be6 14.Nxd5 Nxe5 15.Nxe6 fxe6 16.Rxe6 Qd7 17.Qh5+, or 13....dxc4? 14.Nxc6 Qxd1 15.Raxd1 +-. The game continued 13.Qe2? and now 13....0-0! 14.Bxe7 Nxe7 15.Qxe7 Qxe7 16.Rxe7 dxc4 leaves White in a lost ending. Instead 13....dxc4? 14.Rad1 Bd7  click for larger viewNow simply 15.Ne5!. Black must castle, but: 15....0-0 16.Nxc6 bxc6 17.Bxe7 Qa5 18.Bxf8 (18.Bxf6 is also very strong) leaves Black in a very bad way. And 15....Nxe5 16.Qxe5 0-0 17.Bxe7 Re8 18.Bxd8 Rxe5 19.Rxe5 is even worse. Unfortunately 15.Bxe7?? Qxe7 16.Qxc4 Be6 left White a piece down for not enough. In his calculations, he might have overlooked that Black's bishop was no longer pinned after 15....Qxe7. 15....Nxe7 also would have prepared to give the piece back to reach a winning ending: 16.Ne5 0-0 17.Nxd7 Nxd7 18.Qxe7 Qxe7, etc. In the game, 17.Rxe6 fxe6 18.Re1 0-0 19.Rxe6 still looks like something, but 19....Qb4 or ...Qf7, as well as the text move, refute it. You can't expect Rothman to play like Tal, much less Stockfish. But Denker never should have gotten away with getting so far behind in development and then opening up the center. |
