1. e4 e5 2. Nf3 Nc6 3. Bb5 a6 4. Ba4 Nf6 5. O-O Ne4 6. d4 b5 7. Bb3 d5 8. de5 Be6 9. Nbd2 Nc5 10. c3 d4 11. Be6 Ne6 12. cd4 Ncd4 13. Ne4 Be7 14. Be3 Nf5 15. Qc2 O-O 16. Nf6
 
This is considered harmless but, a player myself of the Open Spanish as Black, I knew it was not so easy in practice.
 
16... Bf6 17. Qf5 Be7 18. Rfd1
 
[18. Rad1 Qc8 19. Qc2 (19. Nd2 Rd8 20. f4 (20. f4 Nd4 21. Qe4 Nf5 drawish position) (20. f4 g6!?) 20... c5 21. Qh3 Rd3? 22. Ne4 Rd1 23. Rd1 Qc7 24. Nc3 Rd8 25. Nd5 Qb7 26. Qf3 Kh8 27. Ne7 Qe7 28. Rd8 Qd8 Van der Wiel-Kortschnoj/Sarajevo/1984/1/2-1/2 (45)) 19... c5 20. Nd2 Qc7 21. f4 c4 22. Ne4 Bc5 23. Qf2 Rac8 24. f5 Be3 25. Qe3 Qe5 26. fe6 f5 27. Qc3 Qe4 Tilak-Jakubovics/London LB (07) 1994/1-0 (43)]
 
18... Qc8 19. Rac1 Rd8 20. Rd8 Qd8 21. Qe4 c5 22. b3 Ra7 23. g3
 
The new move based on the same idea, White is playing comfortably for the endgame. [23. h3 Qa8 24. Nd2 Qe4 25. Ne4 Rc7 26. f4 c4 27. bc4 Rc4 28. Rc4 bc4 29. Kf2 White has a moderate advantage Bellin-Botterill, BCF-ch 1987]
 
23... g6 24. Kg2 Kg7 25. h4 h5 26. Rc2 Rd7?
 
It was necessary to play 26...c7 or 26...b6 to avoid penetration via c6
 
27. Qc6! Rd1 28. Rd2 Rd2 29. Nd2 Nd4 30. Bd4 cd4
 
Puting all hopes in advancing quickly this passed pawn. [30... Qd4 31. Nf3 White has a decisive advantage]
 
31. Ne4!! d3 32. Nd6 f6
 
[32... d2? 33. Qd5 White has a decisive advantage] [32... Bd6 33. ed6 Kf6 34. Qd5 Qd7 was probably the best defence, but White should be winning. (34... d2? 35. Qg5!)]
 
33. Qd5 Qg8 34. ef6 Bf6 35. Qd3 Qe6 36. Ne4 Be7 37. Qd4 Kh7 38. Nd2! Qc6 39. Qe4 Qd6 40. Nf1 Kg7 41. Ne3 Bf6 42. Qb7 Kh6 43. Qf7 Qc6 44. Nd5 Bg7
 
Up to here it was nice.
 
45. Kh2
 
[45. Qf3! was the simplest positional win to put f4, my original idea when I played 38.d2, but the h6 suggested playing for mate.]
 
45... Qc2 46. Ne7?
 
I played this a tempo and it is hard to believe that the position is now drawn, it should not be, but from now on, the win, if it really exists is problematic and I used a lot of time. [46. Nb4!? Qc8 (46... Qd2 47. Na6 Qa2 48. Nc7 White has a moderate advantage) 47. Kg2 White is on the way to an easy win.] [46. Kg2 yes, it was still time to go back 46... Qa2? 47. Nf4 Qc2 48. Ne6! White has a decisive advantage  g5, g8]
 
46... Kh7! 47. a3?! a5 48. a4 ba4 49. ba4 Qe4 50. Kg1 Qe1 51. Kg2 Qe4 52. Kh2 Qc2 53. Qf4 Be5! 54. Qf7 Bg7 55. Qf4 Be5 56. Qe3 Bg7! 57. Qb6 Qe4 58. Qd8 Qa4 59. Qg8 Kh6 60. Qf7 Qc2 61. Ng8 Kh7 62. Nf6 Kh6 63. Ng8
