1. e4 e5 2. f4 exf4 3. Nf3 Nf6 4. Nc3 d6 5. Bc4 Be7 6. O-O Nxe4 7. Nd5 O-O 8. Nxe7+ Qxe7 9. Re1 d5 10. Bb3 Qc5+ 11. d4 Qd6 12. c4 c6 13. cxd5 cxd5 14. Ne5 f6 15. Nd3

15. Rxe4 leads only to a small advantage for White after 15... fxe5 16. dxe5 Qc5+ 17. Qd4 Qxd4+ 18. Rxd4 Be6 19. Bxd5 Bxd5 20. Rxd5

15... Kh8

Obviously not 15... g5 when 16. Rxe4 wins a piece, because the Black d-pawn is pinned

best for Black was probably 15... Be6 16. Bxf4 Qb6

16. Bxf4 Qd8 17. Nc5 Nxc5?

Black had to play 17... f5

18. dxc5 Nc6 19. Bd6 Re8 20. Rxe8+ Qxe8 21. Qxd5 Nb4 22. Qd2 Nc6 23. Re1 Qd8 24. Bc7! Qd7?

The Bishop cannot be taken because of 24... Qxc7 25. Re8#

Black had to play 24... Qf8

25. Qd6

Again trying to exploit the back rank mating possibilities but the killer move here was 25. Qd5!! (threatening mate on g8 rather than f8) and followed by 25... Qxd5 (25... Ne7 26. Rxe7 Qxe7 27. Qg8#) 26. Re8+ Qg8 27. Rxg8#

25... h5 26. Qf8+ Kh7 27. Qg8+ Kh6 28. Bf4+ g5

Black also loses after 28... Kg6 29. Bc2+ f5 30. Rd1 Qf7 (30... Nd4 31. Be5) 31. Rd6+

29. Bd6

Another way to win was 29. Bf7 Qd4+ ( or 29... Qxf7 30. Qxf7 gxf4 31. Qxf6+ Kh7 32. Re8) 30. Kh1 Bf5 31. Bxg5+ fxg5 32. Re6+ Bxe6 33. Qg6#

29... h4 30. Bf7

Another winning line was 30. Bf8+ Kh5 31. Bf7+ Kg4 (or 31... Qxf7 32. Qxf7+ Kg4 33. Re4+ Kf5 34. Qh7#) 32. Re4+ Kf5 33. Qg6#

30... Qf5

30... Qxf7 would only have delayed the inevitable.

31. Bf8# 1-0
