1. d4 Nf6 2. c4 e6 3. Nc3 Bb4 4. e3 O-O 5. Nf3 d5 6. Bd2 b6 7. Be2 Bb7 8. O-O dxc4 9. Bxc4 a6 10. Rc1 Nbd7 11. Qe2 b5 12. Bd3 c5 13. Bb1 cxd4 14. exd4 Nb6 15. Rcd1 Rc8 16. Ne5 Nc4 17. Bg5 Be7 18. Rd3 g6 19. Re1 Nd6 20. Rh3 Re8 21. Qd3 b4 22. Nxf7?!

Daring but not quite accurate. The best move is 22. Rxh7!! e.g. 22... Rxc3 ( Black does not have time for 22... bxc3? 23. Bxf6 Bxf6 24. Nxf7) 23. Bxf6 Bxf6 24. bxc3 Bxe5 25. dxe5 Kxh7 26. exd6.

22... Nxf7 23. Rxh7 Ne4?

The losing move. Instead 23... Be4! gives Black the advantage.

24. Nxe4 Bxg5 25. Nd6! Nh8 26. Rxh8+ Kxh8 27. Nf7+ Kg7 28. Qxg6+ Kf8 29. Nxd8 Bxd8 30. Qh6+ Kf7 31. Qh7+ Kf8 32. Bg6
