This was something I worked on around 2003-2004, had to drag this up out of the depths because I've practically forgotten what all those symbols mean.

The gist is that after 10... Qa5, Black is busted, although things may have changed in the past 5 years.

1. e4 c5 2. Nf3 d6 3. d4 cxd4 4. Nxd4 Nf6 5. Nc3 g6 6. Be3 Bg7 7. f3 0-0 8. Qd2 Nc6 9. Bc4 Bd7 10. 0-0-0 Qa5 11. h4 Rfc8 12. Bb3 Ne5 13. g4:

A) 13... Nc4 14. Bxc4 Rxc4 15. h5 Rac8 16. Nb3 Qa6 17. hxg6 fxg6 18. e5 Ne8 19. Qh2 h5 20. Bd4 Rxd4 21. Rxd4 Rxc3 22. bxc3 Bxe5 23. Qd2 and White has a clear advantage.

B) 13... Rc4 14. g5 Nh5 15. f4 Rxd4 16. Qxd4 Ng4 17. e5 Ng3 18. Rhe1 Nf5 19. Qd5 Qxd5 20. Nxd5 e6 21. Bg1 exd5 22. Bxd5 and White wins.

C) 13... b5 14. h5 Nc4 15. Bxc4 bxc4 16. Bh6 Bh8 17. Nf5 Re8 (17... Bxf5 18. exf5) 18. Qg5 (18. hxg6 fxg6 19. Bg7 also wins) Qb6 19. hxg6 fxg6 20. Bg7 and White wins, Nunn-Ward, 1998.

D) 13... b5 14. h5 b4 15. Nd5 Nxd5 16. exd5 Nc4 17. Qf2 Nxe3 (17... Qxd5 18. hxg6 hxg6 19. Qh4 Qe5 20. Bg5) 18. Qxe3 Qc7 19. Qxe7 Re8 20. Qh4 a5 21. hxg6 fxg6 22. f4 a4 23. f5 Qd8 24. f6 Qxf6 25. g5 Qd8 26. Ne6 Bxe6 27. dxe6 axb3 28. exf7+ Kxf7 29. Qc4+ and White wins.

Merry Christmas.
