Move

1. e4 e5 2. Nf3 Nc6 3. Bb5 a6 4. Bxc6 dxc6 5. O-O Bg4 6. h3 h5 7. d3 Qf6 8. Nbd2 Ne7 9. Re1 Ng6 10. d4 Nf4!?
   10..Bd6 is the more usual move here, when play can continue : 11.hxg4 hxg4 12.Nh2 Rxh2 13.Qxg4 Qh4 14.Qxh4 Rxh4 15.Nf3 Rh8+=, when white has a slight advantage in the ending as he can create a passed pawn on the kingside, whereas blck can not do so on the queenside due to his doubled pawns. This occurred in a previous game against Joe (Master Grand Prix, Dublin 1993, 1-0, 48 moves). Having lost the above game, I had prepared the move played which leads to double-edged play.
11. hxg4 hxg4 12. Nh2?
   12.g3 is the recommended move here, when play can continue 12..gxf3 13.Qxf3 Ne6 14.dxe5 Qh6 15.Nb3 Qh2+ 16.Kf1 Bc5 with complications
Nxg2! 13. Ndf1
   13.Kxg2? Rxh2+! (This occurred in a game of mine against J. Brookes, Hastings Experts 1996 - my opponent resigned here.) 14.Kxh2 Qxf2+ 15.Kh1 g3, when black has unstoppable mating threats.
Nxe1
   This is where my opening preparation ended
14. Qxe1 Bd6
   Endeavouring to complete development as quickly as possible
15. Nxg4 Qh4 16. Nfh2 O-O-O 17. Qe2 f5!
   Forcing open the centre and putting pressure on white's knights
18. dxe5
   18.exf5 e4! 19.f4 exf3, when black is winning one of the knights, with a significant advantage
Bxe5!
   Better than 18...fxg4 19.Qxg4+ Qxg4+ 20.Nxg4, when white gets some play for the exchange
19. exf5
   19.f4 fxg4 20.Qxg4+ Qxg4+ 21.Nxg4 Rd1+ 22.Kg2 Bxf4 wins easily for black
Bxh2+ 20. Kf1 Qh3+
   20..Bf4 is better
21. Ke1 Bd6-+
   Black is the exchange up and white has a badly placed king
22. Ne3 Qh1+ 23. Nf1 Rhe8 24. Be3 Bc5 25. Rd1 Rxd1+ 26. Kxd1 Bxe3 27. fxe3 Qe4 28. Qf2 Qd5+ 29. Nd2 Qxa2 30. b3 Qa1+ 31. Ke2 Qc3 32. e4 Qxc2 33. f6 gxf6
   33..Rxe4+! wins white's queen in a few moves
34. Qf5+ Kb8 35. Qd7 Rxe4+ 36. Kf3 Rb4 37. Qe8+ Ka7 38. Qe3+ b6 39. Qe7 Qc3+ 40. Ke2 Kb7 41. Nc4 Rxc4 42. bxc4 Qxc4+ 43. Kd2 Qd5+ 0-1
