timely f2-f4. 22. ... Bxc6 23. cxd5 Bxd5
Black eagerly trades his bad bishop.
24. Rxa8 Rxa8 25. Bxd5 exd5 26. Qb3 Due to the weaker pawn stucture, Black
must seize the initiative, lest he become a casualty of grandmaster technique.
26. ... f4!
The only move, even if your online moniker is not fpawn.
27. exf4 gxf4 28. Bc1 fxg3 29. hxg3 Black seems content after 29. fxg3 Re8 30. Bf4 Re4.

Pacific Coast Open, Agoura Hills (2), 07.21.2006 Notes by Aigner
1. Nf3 f5 2. b4!?
While rare on move two, the b2-b4- concept is hardly new.
2. ... Nf6 3. Bb2 g6 4. g3 Bg7 5. Bg2 0-0 6. c4 d6 7. d4 Transposing into a known position.
7. ... Ne4 A fight for the center ensues after 7. ...
e5 8. dxe5 Ng4 9. c5 Nxe5 10. Qb3+ Kh8 11. 0-0.
8. Nbd2 9. Qxd2 e6
The time for ... c7-c5 has passed since White controls the dark squares.
10. 0-0 Nd7 11. Rac1 Nf6 12. Rfd1 Qe8 13. Qc2 Bd7 14. b5
White has more space, but Black has no weaknesses yet. 14. ... a6 15. a4 axb5 16. axb5 Ne4 The knight belongs in the center, but
here it should encounter trouble. See my next note.
17. Nd2 Qf7 18. e3?!
White's advantage increases after 18. Nxe4 fxe4 19. Rf1 d5 20. f3! 18. ... Nxd2 19. Qxd2 c6 20. Qb4 d5 The stonewall pawn structure never
earns style points, but proves hard to crack.
21. Ra1 g5!? 31. Be3 h5! Black further probes the kingside.
32. Kg2 h4 33. f3 Re7 The computer suggests 33. ... h3+ 34.
Kf2 Re7 35. Rh1 Qh5 with dynamic equality.
34. gxh4 Qe6 A sharper move 34. ... Bf6 35. Rh1 Qe6
36. Bg5 Rg7 leaves White hanging on the precipice.
35. Bf2 Bh6! 36. f4? White makes an awful choice in time
pressure. Better was 36. Bg3 Qe2+ 37. Kh3 Qe6+ 38. Kh2 Rg7 39. Rg1 Bf4 40. Bxf4 Rxg1 41. Kxg1 Qe1+ 42. Kg2 Qe2+ 43. Kh3 Qe6+ 44. Kg3 Qe1+ with a perpetual.
8. ... Nxd2?!
More to the point is 8. ... c5 9. 0-0 Nc6 exploiting the pin on the long diagonal.

22. bxc6 White could lock the kingside with a
36. ... Qe4+ 37. Kh3 No better is 37. Qf3 Rg7+ 38. Bg3 Bxf4. 37. ... Rg7 38. Bg3 Bxf4, White resigned.
29. ... Re8 30. Bf4? This move loses a tempo. White’s
position is increasingly difficult for a human to defend, especially in Zeitnot.
30. ... Re4
