Schipkov, Boris - Ruban, Vadim [D31]
Novosibirsk Region ch 1986

Notes by Boris Schipkov

1. d4 d5 2. c4 e6 3. Nc3 c6 4. cxd5
Interesting was 4.e4, but I supposed that Vadim was very well prepared in this line.
4...exd5 5. Bf4 Bf5 6. e3 Bd6!? 7. Bxd6
Deserving attention is 7. Nge2!? Nf6 8. Bxd6 Qxd6 9. Ng3 Bg6 10. h4 with some initiative.
7...Qxd6 8. Bd3








   
8...Nh6
More precise is 8... Bxd3 9. Qxd3 Nf6 with equality. In the game Cunningham, W - Krush, I, New York op 2000 Black obtained an advantage after 10. Nf3 Nbd7 11. O-O O-O 12. b4 (12. Rab1) 12... b5 13. a4 a6 14. Rfb1 Nb6! 15. a5? (15. Ne5!? Nc4 16. Qf5) 15... Nc4 16. Ra2 Rae8 17. Nd2 Ng4 18. Nf1 f5 19. h3 Nh6 20. Re2? f4! 21. exf4 Qxf4.
9. Nf3 Nd7 10. O-O O-O 11. Bxf5 Nxf5 12. Qd3! Qe6
Better is 12... Qg6!? 13. b4 Nh4 14. Qxg6 Nxf3+ 15. gxf3 fxg6.
13. b4! b5 14. a4 a6








   
15. e4!
A classical response. White meets opponent's activity on the queenside with the e4 advance in the centre. I planned this subtle idea beforehand because I had seen few Ruban's games with ...Nb6-c4 manoeuvre after ...b7-b5 with nice play for Black.
15...dxe4 16. Nxe4 Nd6
Or 16...Rad8 17. Rfe1 Qg6 18. axb5 axb5 19. Ra7 with a small but lasting edge to White.
17. Nc5! Nxc5 18. dxc5 Nf5?!
Stronger is 18...Nc4 19. Rfe1 Qf6 20. Qe4 h6, and White has only a minimal advantage.
19. Rfe1 Qf6 20. Qe4








   
20...h5
A magnificent position. White, controlling the central squares and open file, gained a clear advantage. Black c6-pawn is weak.
21. Ne5 Rae8 22. axb5 axb5 23. Ra6 Nh6!? 24. f4 Qd8 25. Rxc6 Qa8?
A mistake. Correct is 25...Ng4!? 26. h3 f5 27. Qd3 Rxe5 28. Qb3+ Qd5 29. Qxd5+ Rxd5 30. hxg4 fxg4 31. Rb6 Rxf4 32. Rxb5 Rd2 33. c6 Rc4 34. Rxh5 Rxc6 35. Rg5 with advantage to White in the endgame.
26. Qf3 f6 27. Nd3 Rxe1+ 28. Nxe1 Qa1 29. Qe3?
Time trouble. After 29. Qd5+! Kh8 30. Re6 White wins.
29...Ng4 30. Qe6+ Kh8 31. Rd6 Qb1 32. h3
Also possible is 32. Rd5!?
32...Ne5 33. fxe5
Interesting was 33. Kf1, but I had only few seconds.
33...Qxe1+ 34. Kh2 Qxb4 35. exf6 Qf4+ 36. Kg1 Qc1+ 37. Kh2
Draw by perpetual check. 1/2-1/2
