4NCL Bristol v NW Eagles, 2007
1. e4e5 2. Nf3Nc6 3. Nc3Nf6 4. d4exd4 5. Nxd4Bb4 6. Nxc6 Standard four knights position - now Black should recapture with b pawn 6... dxc6 capturing with the d pawn allows White to exchange into superior ending 7. Qxd8+Kxd8 8. Bg5h6 9. O-O-O+Ke7 10. Bh4g5 11. Bg3Bxc3 12. bxc3Black has a slightly superior pawn structure but White has the bishop pair and a more active position 12... Be6 13. f3Ne8 14. Kb1Nd6 15. Bd3Raf8 16. h4Kd7 17. hxg5hxg5 18. Be5Rxh1 19. Rxh1White seizes control of open file using bishop pair; the position is better for White 19... Rg8 20. g4 A careless move overlooking a simple tactic that equalises the position 20... Nc4 21. Bxc4Bxc4 22. Rh2c5 23. a3Rg6 24. Kc1Ra6 25. Kb2Re6 26. Bg3Rf6 Black is going to attack f3 weakness and force White to relinquish the h file, Black is slightly better but White will hold an opposite coloured bishop endgame 27. Rf2Rh6 28. Rd2+Kc6 29. Rh2 White offers an exchange of rooks into an opposite coloured Bishop endgame and in doing so sacrifices a pawn; I had calculated that it was a draw 29... Rxh2 30. Bxh2Be2 31. f4gxf4 32. Bxf4Bxg4 33. Bg5White needs to be accurate to implement his idea of a dark square blockade 33... Bf3 34. e5Kd5 35. Bf6b5 36. Bg7a5 37. Bf6Kc4 38. Bd8b4 39. cxb4axb4 40. axb4cxb4 41. Bxc7Bd5 42.
