1. e4 e5 2. Nf3 Nc6 3. Bb5 a6 4. Ba4 Nf6 5. O-O Be7 6. Re1 b5 7. Bb3 d6 8. c3 O-O 9. d4 Bg4 10. d5 Na5 11. Bc2 Qc8 12. Nbd2 c6 13. b4 Nc4 13... Nb7 is the other main move here when the knight can come back into play via d8 and e6. 14. Nxc4 bxc4 15. dxc6 Qxc6 16. a4 h6 16... a5!? is a double-edged try here. Black gives White a protected passed pawn in exchange for the c5 square for his knight. 17. a5!? This seems to be Becerra's new idea in this position. A few days after this game I received the June 2005 issue of Chess Life which had the game Becerra-Goldin (1-0) from the US Amateur Team Championship. The position seems pretty balanced, but Black has to figure out what squares to develop his pieces to. 17... Rfd8 17... Rfe8? 18. Ba4 is one point of White's move The immediate 17... Qb7 was Goldin's choice. 18. h3 Be6 19. Qe2 Nd7 19... Rac8 20. Bd2 Qb7 21. Rad1 Bf8 transposes to Becerra-Goldin, where Julio played 22. Nh2 but 22. Nh4 similar to the present game, looks stronger. My thought was that b5 might be a good square for my knight via b8-c6-a7, but it isn't clear that is a good plan. On f6 the knight could help support a d5 break as well as keeping an extra defender on the kingside. 20. Bd2 Qb7 21. Rad1 Bf8 22. Bc1 Rac8 23. Nh4 g6 I wanted to keep the knight out of f5.

24. Nf5! d5 The sacrifice cannot be accepted 24... gxf5 25. exf5 Bd5 26. Qg4+ Kh8 27. Qh4 and White's attack is winning 25. Nxh6+ Kh7 25... Bxh6 26. Bxh6 d4 had to be played when White is much better. Instead, the floodgates are opened and the White pieces pour in. 26. exd5 Bxd5 27. Qh5 Nf6 28. Qh4 Bxg2 29. Ng4+ [1:0]
