A very poisoned pawn

Hikaru Nakamura caught the teenage prodigy Anish Giri in the race for a place in the 2011 Amber Rapid and Blindfold tournament.

 By Malcolm Pein
This lucrative event is open only to a select group. Nakamura won brilliantly against Loek Van Wely in the penultimate round of the NH Hotels 'Rising Stars v Veterans' tournament in Amsterdam and then held the draw against Boris Gelfand with black as Giri faltered. The pair finished on 6/10 and Nakamura, the king of the Internet Chess Club, won a speed chess tie break.
Giri lost to Peter Heine Nielsen from a passive position but the Rising Stars defeated the Veterans overall 26-24. David Howell ended with a very respectable 4.5/10. In the last round, Howell sacrificed his queen against Peter Svidler and appeared lost. He turned the position round to such an extent it might have been tenable before an ending arose with rook, ‘a’ pawn and ‘e’ pawn against queen. Svidler manoeuvred to win both pawns and won on move 107.

1.e4 c5 2.Nf3 d6 3.d4 cxd4 4.Nxd4 Nf6 5.Nc3 a6 6.Bg5 (This move was considered the most dangerous until Fischer and Kasparov honed the Poisoned Pawn but it is back again) 6…Nbd7 (Avoiding 6…e6 7.f4 Qb6 8.Qd2, the Poisoned Pawn) 7.f4! Qb6 8.Qd2! Qxb2 9.Rb1 Qa3 10.Bxf6! Nxf6 (This version of the Poisoned Pawn looks so potent there may be no antidote, but 10...gxf6 11.Nd5 Rb8 may survive longer) 11.e5 dxe5 12.fxe5 Nd7 13.Nd5! Qc5 (13...Rb8 14.Nc6 bxc6 15.Rxb8 Nxb8 16.Nc7#) 14.Nb3 Qc6 15.Na5 Qc5 16.Nxb7 Qc6 (16...Bxb7 17.Rxb7 Rc8 18.Bxa6 with Bb5 or Rxd7 next)17.Rb6!! 1-0 A bombshell, 17…Nxb6 18.Nf6+! Qd8 and 17…Qa4 18.Nc7 are both mate.
Black’s opening is by no means as bad as it looks. He had two clear improvements after the initial piece sacrifice.
