1. e4 g6 2. d4 Bg7 3. Nc3 c6 4. Nf3 d5 5. Be3 Bg4 6. h3 Bxf3 7. Qxf3 e6 8. O-O-O Nd7 9. exd5 cxd5 10. Nb5 Kf8 11. Bf4 Bf6 12. Bc7 White is better of course, but it's not clear if this is a good square for the bishop. 12... Qc8 13. Rd3 Ne7 14. Bd6 Kg7 15. g4 Nc6 16. h4 h6 17. Kb1 a6 18. g5!? Very interestingly played. 18. Nc7 Nxd4 19. Qg3 Ra7 18... hxg5 18... axb5 19. gxf6+ Nxf6 seems an option as well. 19. Nc7 Nxd4! 20. Qd1 White didn't fancy the, perhaps better, sequence 20. Rxd4 Bxd4 21. hxg5 Rxh1 22. Qxh1 Kg8 23. Nxa8 Qxa8 20... Nf5 21. hxg5? Couragious, but incorrect. 21. Bh2 21... Rxh1 22. gxf6+ Kg8 22... Nxf6 23. Be5 is slightly more difficult to play. 23. Bf4 Ra7 Even stronger is 23... e5! 24. Nxa8 exf4 25. Rxd5 Nf8 because of the last pointe 26. Nb6 Qc6 24. Rh3 Rxh3 25. Bxh3 b5 26. Bxf5 Nice but not enough is 26. Nxe6 fxe6 27. Bxf5 Nxf6! (27... gxf5? 28. Qg1+) (27... exf5? 28. Qxd5+ Kh8 29. Qh1+ Kg8 30. Qd5+=) 28. Bxg6 Rg7 26... Rxc7 27. Bxc7 Qxc7 28. Bd3 Nxf6 29. Qf3 Qe5 30. a3 Kg7 31. Ka2 Qd4 32. c3 Qe5 33. Qd1 Ne4 34. Qe2 Qf4 35. Bxe4 Qxe4 36. Qxe4 dxe4 37.
