Zvjaginsev, V. (2675) - Bocharov, D. (2571) [B20]
Russian Championship, Tomsk (7) 2006

Notes by Boris Schipkov

1. e4 c5 2. Na3
A bad move according to general principles.








   
2...g6!?
A nice idea. Also 2...Nc6 is playable, but in that case White can develop his bishop at once by 3. Bb5 g6 4. Bxc6 bxc6 5. d3 Bg7, Zvjaginsev, V - Motylev, A, RUS-ch Superfinal, Moscow 2005.
3. c3 Bg7 4. Nf3 Nc6 5. d4 cxd4 6. cxd4








   
6...Nf6!?
A novelty. In the game Batsiashvili, N - Dzagnidze, N, GEO-ch (Women) 2006, Black played 6...d6 7. h3 (7. d5!?) Nf6 8. Bd3 O-O 9. O-O a6 10. Be3, and here she could continue with 10...Nb4.
7. d5
Black obtains a good game after 7. e5 Ne4 8. Nc4 d5 9. exd6 O-O!? (9...Nxd6) 10. d5 Na5 11. dxe7 Qxe7 12. Ne3 Qb4+ (12...f5 13. Be2 f4 14. Nc2 b6 15. O-O Bb7) 13. Nd2 Re8 14. Bd3 Nc4 15. Bxc4 Nxd2 16. Bxd2 (16. Qxd2 Qxc4 17. Qe2 Qe4 18. f3 Qb4+ 19. Kf2 Bd7) 16...Qxc4 17. Qe2 Qxe2+ (17...Qe4) 18. Kxe2 Bxb2 19. Rab1 Bd4.
7...Nb4 8. Bd3
White could sacrifice the e4-pawn with 8. Bc4 Nxe4 9. O-O f5 (9...Nd6 10. Bf4 Nxc4 11. Nxc4 O-O 12. d6) 10. Ng5 O-O 11. Qb3 a5 12. Qh3 Nf6 13. Re1, with compensation.
8...O-O 9. O-O








   
9...d6?!
More precise is 9...Nxd3!? 10. Qxd3 d6 11. Be3, and now Black gets counterplay with 11...Bd7 12. Rac1 Qa5 13. Nc4 Qa6 14. b3 Rac8 15. a4 e6, and with 11...e6 12. dxe6 Bxe6 13. Nb5 d5 14. e5 Nd7 15. Bd4 a6 16. Nc3 Re8, or even with 11...Nh5 12. Nb5 (12. Nd4 e5, 12. Bd4 Nf4) 12...f5.
10. Bc4!
White logically keeps his bishop.
10...Bg4
The stupid 10...Nxe4? is met by the fork 11. Qe1.
11. h3 Bxf3 12. Qxf3 Rc8








   
13. Qb3?
The critical moment. After the text White begins to fall into an abyss. Correct is the solid 13. Qe2! Nd7 14. Be3 Nc5 15. Rac1 a6 (15...Nxe4 16. Nb5 a6 17. Na7 Ra8 18. a3 b6 19. axb4 Rxa7 20. Bxa6 or 15...Na4 16. Nb5 Bxb2 17. Rb1 a6 18. Bb3 axb5 19. Bxa4 bxa4 20. Qxb2 Nd3 21. Qd4 Nc5 22. Bh6 e5 23. dxe6 Nxe6 24. Qxa4 Re8 25. Rxb7) 16. Qd2! a5 17. f3 Qd7 18. Bb5 Qd8 19. b3 f5 20. exf5 Rxf5 21. Bc4 e6 22. g4 Rxd5 23. Bxd5 Nxd5 24. Bg5 Qf8 25. Nb5 with advantage to White.
13...a5 14. Re1 Nd7 15. Bf1?!
Better is 15. Rb1 f5 16. exf5 Rxf5 17. Be3 or 15. Re2.








   
15...f5!
A strong break. Black launches an attack.
16. exf5 Rxf5 17. g4?!
White weakens his kingside. But after 17. Be3 Nc5 18. Bxc5 Rxc5 19. Be2 Qf8 20. Bf3 Rxf3!? (20...Rf4) 21. gxf3 (21. Qxf3 Qxf3 22. gxf3 Bxb2) 21...Qf5 22. Re4 Nxd5 23. h4 (23. Rg4 h5) 23...Kh8 24. Rd1 (24. Qxb7 Be5 or 24. Nc4 b5 25. Nxa5 Be5 26. Nb7 Rc4) 24...h5 25. Nc4 g5 26. hxg5 Nf4 27. Ne3 Qxg5+ 28. Kf1 Qh4 29. Ke1 Qh1+ 30. Nf1 Be5 Black has the better chances as well.
17...Rf7 18. Nc4








   
18...b5!
Winning.
19. Ne3 Qb6!?
Black may win also with 19...Ne5 20. Be2 Nbd3! 21. Bxd3 Nf3+ 22. Kf1 Rxc1 23. Raxc1 Nd2+ 24. Kg2 Nxb3 25. axb3 Qb6 or with 19...Qf8 20. Bxb5 (20. Re2 Ne5) 20...Rxf2 21. Bxd7 Qf3.
20. Bd2 Nc5 21. Qd1
Or 21. Qa3 Ne4 (21...Rcf8) 22. Re2 Rcf8 23. Bxb4 axb4 24. Qxb4 Nxf2 25. Bg2 Bd4.
21...Ne4 22. Bxb4 axb4 23. Rc1








   
23...Rcf8!
The f2-square is an Achilles' heel of White.
24. Rc6 Qa7 25. Qd3 Nxf2 26. Qxb5








   
26...Nd1
Black grabs material.
White resigned. 0-1
