Move

1. d4 d5 2. c4 dxc4 3. Nf3 c5 4. e3 Nf6 5. Bxc4 e6 6. Qe2 a6 7. dxc5 Bxc5 8. O-O Nbd7 9. e4 Qc7?!
   Black allows e4-e5, which puts him into danger.
10. e5! Ng4 11. Bf4 b5 12. Bb3 Bb7 13. Nbd2 O-O 14. h3?!
    Probably I should not hurry with this move: 14.Rac1 Qb8 15.Bc2 looks better, leaving h2-h3 as a threat and not allowing the Knight to come back to f6 and then to d5.
Ngf6 15. Rac1 Qb8
    Black could not play 15...Nd5?? in view of 16 Bxd5 Bxd5 17 b4+-.
16. Bc2 Rc8?
   Black keeps the tension (the Knight on f6 - the Bishop on f4), but this is fatal for him, as when the Knight will have to retreat, it will be too late! The only move was 16... Nd5, when the sacrifice on h7 did not quite work yet: 17 Bxh7+?! Kxh7 18 Ng5+ Kg8 19 Qh5 N5f6!. I planned to play 17 Bh2 with initiative.
17. Bh2! Nd5
   Now all Black's pieces are far away from his king and so a typical sacrifice on h7 is called for:
18. Bxh7+! Kxh7 19. Ng5+ Kg8
    Black also loses after 19...Kh6 20 Qg4 or 19...Kg6 20 h4 (threatening 21 Qe4+).
20. Qh5 Nf8?
   Black was chance was in 20...Nxe5!, when White would have to play energetically to prove his advantage. Still, White wins after 21 Bxe5! Qxe5 22 Qxf7+ Kh8 23 Nde4! This is the only winning move, as 23 Qxb7? Qxg5 24 Rxc5 Rcb8! 25 Nf3 Qxg2+ 26 Kxg2 Rxb7=, 23 Rxc5? Rxc5 24 Qxb7 Qb8 or 23 Ndf3? Bxf2+! 24 Kxf2 Qxb2+ 25 Kg3 Rxc1 26 Rxc1 Qxc1 27 Qh5+ Kg8 28 Qf7+= won't do. Now after 23...Rc7 24 Rxc5! Black is doomed.
21. Qxf7+ Kh8 22. Qh5+ Kg8 23. Qf7+ Kh8 24. Nde4
   This is the decisive manoeuvre, as after 24...Be7 White plays 25 Nf6! gxf6 26 exf6+-.
Qa7 25. Rxc5 Rxc5 26. Nxc5 Qxc5 27. Qxb7+- Qc8 28. Qf7 Rb8 29. Bg3 Rb7 30. Qh5+ Kg8 31. Rd1 g6 32. Qg4 Ne7 33. Ne4 Qc2 34. Rd8 Kg7 35. Qh4 Nd5 36. Rxf8 Kxf8 37. Qh8+ Ke7 38. Bh4+ g5 39. Bxg5+ Kd7 40. Qd8+
   Time: 1.56 - 1.51.
