Kuporosov, V. - Schipkov, B. [B33]
Gyor HUN-ch open (3) 1990

Notes by Boris Schipkov

In this game I managed to demonstrate harmless of the variation 7. Nd5 for Black. It is necessary to note, that this game is given in many bases with a wrong White's 32nd move.
1. e4 c5 2. Nf3 Nc6 3. d4 cxd4 4. Nxd4 Nf6 5. Nc3 e5 6. Ndb5 d6 7. Nd5 Nxd5 8. exd5 Nb8!
Slightly weaker is 8...Ne7. In this case Black wastes several tempi, moving a knight on a route e7 - f5 - h4 -g6. If he stands a knight on f5 and continues development with a fianchetto, then White has edge, as it was demonstrated in the game Yudasin,L-Kramnik,V Wjik aan Zee m(3) 1994: 8...Ne7 9.c3 Nf5 10.a4 g6 11.Bd3! Bg7 12.0-0 0-0 13.Qb3 Re8 14.Re1!.
9. c4 Nd7 10. Be2 Be7 11. O-O a6 12. Nc3 O-O 13. a3 f5 14. b4 Bf6 A novelty. Not bad and 14...e4 15.Be3 Bf6 16.Bd4 Be5 17.Bxe5 Nxe5 18.Qd4 Bd7 19.c5 Qf6 20.Rfd1 Rfc8 21.Rac1 Rc7 22.h3 Qe7 with a sharp struggle in the game Yudasin,L-Kharlov,A URS ch-58 1991 (0-1, 39).
Worse is 15...f4?! 16.Bd4 f3 17.gxf3 exf3 18.Bxf3 with an extra pawn in Yudasin,L-Horvath,Cs Leningrad 1989.
15. Be3 e4 16. Bd4 Be5 17. Qd2
17.Bxe5 Nxe5 leads to Yudasin,L-Kharlov,A URS ch-58 1991.








   
17...Rf6! Creating threats on the kingside.
18. f4 exf3 19. Bxf3 Rh6 20. Bxe5 Nxe5 21. Be2 Qb6+ 22. Kh1 Bd7 23. Rac1
If 23.Nd1, then 23...a5 or 23...Qd8 with equal chances.
23...a5 24. Rb1 axb4 25. axb4 Rc8 26. Rf4 Qd8! The position is equal.
27. Rd4 Rh4 28. c5 dxc5 29. bxc5 Rxc5 30. Rxb7 Rxd4 31. Qxd4 Qc8








   
32. Rb3
In the game the move 32. Rb3 was made. If White would continue 32. Rb6?, as is written in various chess bases, then after the simple 32...Rxc3 Black wins.
32...Nf7 33. Ba6!?
White tried to complicate struggle in mild time-trouble.
33...Qc7 34. Rb7 Qd6 35. Ra7
35.Rxd7 Rxc3 36.Qxc3 Qxd7 37.Qc6 Qd6 38.Qe8+ Qf8 39.Qe6 Qd6 40.Qe8+ with repetition .
35...h6 36. h3 Ra5 37. Be2 Rxa7 38. Qxa7 Kh7 39. Bb5 Bxb5 40. Qxf7
1/2-1/2 Draw.
