The player of the black pieces had a similar rating to myself but two rounds earlier had drawn with the black pieces against the Russian GM Igor Naumkin. He must have been feeling very confident when realising next he only had little old me to play.
1. d4 Nf6 2. Bg5 g6 3. Nc3 d5 4. f3 Bg7 5. e4 dxe4 6. fxe4 O-O 7. Nf3 Bg4 8. Be2 Nc6 9. d5 Bxf3 10. gxf3 Ne5 11. f4 Ned7 12. e5 Ne8 13. Bh4 (Ed. This move deserves an ! or two. By removing the bishop now Black cannot play f6 with tempo and white can answer f6 with e6. And f6 seems to me to be his only legitimate chance of breaking free.) f6 14. e6 Nb6 15. f5 Nd6 16. Bd3 Nbc4 17. fxg6 Nxb2 18. gxh7+ Kh8 19. Qd2 Keeping everything under control. This was the hardest move to find of the whole game as it would have been easy to start panicking thinking I might have over extended - having seen ahead to the position after black's 21... Ne4 and not even given a thought to castling at this point!
19... Nxd3+ 20. Qxd3 f5 21. Rg1 Ne4 22. Rxg7 Kxg7 23. Nxe4 fxe4 24. Qd4+ Kxh7 25. Qxe4+ Kh6 26. O-O-O Castling on move 26. to apply the final nail in the coffin was great fun to do.
26... Qd6 27. Bg5+ Kg7 28. Bh6+ Kxh6 29. Qh4+ Kg6 30. Rg1+ Kf5 31. Rg5+ Kf6 If there is one one criticism you could level at black's play in hindsight it would be that his opening play was perhaps a little mechanical. However at the time it seemed logical and natural and the same plan is bog standard in similar Grunfeld/Kings Indian type positions. Black admitted to me after the game that he had not seen 13. Bh4 soon enough.
