Na4 { is the cute point that every Poisoned Pawn player must know: as Black no longer controls the a3-square. }) 10. Bf2 Qc7 11. Qf3 Nbd7 12. g4!? (12. O-O-O { is by far the main move here. }) 12... g5! { And this is why! } 13. h4 (13. fxg5 Ne5 14. Qg3 hxg5 15. Be2 b5 { and White's attack has stalled out while Black is ready for White's king to join the party on either flank. }) 13... gxf4 14. Be2 Ne5 15. Qxf4 Nexg4 16. Bxg4 e5! { A nice point. It's always unnerving to see a strong player like Corrales caught out of book, but such as the life for Najdorf players on either side of the board. } 17. Qxf6 Bxf6 18. Nd5 Qa5+ 19. b4 Qxd5! { Not the easiest variation to see in advance! } 20. exd5 Bxg4 21. Rg1 h5 22. Nb3 { When the dust settles, Black is up a clear pawn with the bishop pair and easy play against the weak c2-pawn. } 22... Rc8 23. Kd2 Bf3 { Black is winning. } 24. c4 Rxc4 25. Na5 Rc8 26.
