Novosibirsk 1986
Notes by Boris Schipkov

1. d4 Nf6 2. c4 e6

3. Nc3
The Nimzo-Indian Defence. The continuation 3.Nf3 can lead to the Bogo-Indian Defence after 3...Bb4+ or to the Queen's Indian after 3...b6.
3...Bb4 4. e3 O-O
Or 4...c5 5. Bd3 Nc6 6. Nge2 Bxc3+ 7. Nxc3 cxd4 8. exd4 d5 9. cxd5 Nxd5 10. Be4 O-O 11. O-O Nde7 12. d5 exd5 13. Nxd5 Nxd5 14. Bxd5 Qf6 15. Qf3 Qxf3 16. Bxf3 Nd4 17. Bd1 Bf5 18. Be3 Nc2 1/2, a draw in Schipkov, B - Almasi, Z, HUN-ch op, Gyor 1990.
5. Nge2 d5 6. cxd5 exd5 7. g3

7...c6
Here Mezentsev engrossed in thoughts. I saw that Vladimir did not play against the plan 7. g3 before this game, did not know theory and must think every move. Vladimir Mezentsev is a famous player, he was two times the Champion of Akademgorodok and the Champion of Novosibirsk in 1989, the Champion of California State (1999 Open State Championship, California, USA, 5 out of 6) in 1999, also 2nd place in the Linklater Mem 2002 (7 out of 10, 1-2. Lakdawala, Mezentsev). I was the Champion of Novosibirsk in 1988, 9 from 11, outstripped Vladimir Mezentsev by coefficient (thanks to Stanislav Polyakevich, 4th place, who beat Mezentsev, but lost only to me in 90 moves).
Frequently Black plays 7...Re8 8. Bg2 c6 9. O-O Bf5!? 10. f3 Nbd7 11. g4 Bg6, Schipkov, B - Almasi, Z, Kecskemet 1993, and now correct is 12. Nf4!? Bd6 (12...Nb6, 12...Nf8) 13. Nxg6 (13. h4!?) 13...hxg6 14. e4 c5 15. g5 Nh5 16. Nxd5 cxd4 17. f4 Rc8 (17...Nb6 18. Qxd4 Rc8 19. Kh1, with a small edge) 18. Bd2 (18. e5!?) 18...Nb6 19. Ba5 Nxf4? (19...Rc5) 20. Bxb6 Qxg5 21. Nxf4 Bxf4 (21...axb6 22. Qf3) 22. Bxd4 with an advantage to White in Saidy, A - De Guzman, R, National op, Las Vegas 2004. So 7...c5!? is worthy of attention, 8. Bg2 cxd4 9. exd4 Bg4 10. f3 Be6 11. O-O Nc6, with equality in Khismatullin, D - Aleksandrov, A, Abu Dhabi op 2007.
8. Bg2 Nbd7
White won after 8...Bf5 9. O-O Bd6 10. f3 Qe7 11. Qb3 Na6 12. Bd2 Rfe8 13. Rae1 Qd7 14. g4 Bg6 15. g5 Nh5 16. e4 Nb4 17. Nd1 c5 18. Bxb4 cxb4 19. Qxd5 Rad8 20. e5 Bc7 21. Qxd7 Rxd7 22. f4 Bd3 23. d5 Bc4 24. Bf3 g6 25. d6 Bb6+ 26. Kg2 Bxa2 27. Nf2 Kf8 28. Bxh5 gxh5 29. Ng3 h4 30. Nh5 Bd5+ 31. Kh3 Bxf2 32. Rxf2 Rxd6 33. Nf6 Be6+ 34. Kxh4 Rd3 35. f5 Rd4+ 36. Kg3 Rd3+ 37. Kg4 Rd4+ 38. Rf4 1-0, Schipkov, B - Amalov, I, Russian Spartakiada, Makhachkala 1985.
9. O-O Re8 10. f3 Nf8
The move 10...Nb6 is interesting, 11. e4 dxe4 12. fxe4 Bg4 13. Bg5 Be7, Garcia Palermo, C - Spassky, B, Vienna op 1986.
11. e4!
The main idea in such positions.

11...c5
In the case of 11...dxe4 12. fxe4 Bg4 13. Bg5 Be7 14. e5 N6d7 15. Bxe7 Rxe7 16. h3 Bxe2 17. Qxe2 White had a small edge in Winants, L - Grigorov, G, FRA-chT1A, France 2007.
12. e5
I played quickly, but now 12. Bg5! was better, 12...dxe4 13. fxe4 Bg4 14. Bxf6 gxf6 15. Rf2 cxd4 16. Nd5 Be7 17. Qxd4 Ne6 18. Qd2 Kh8 (18...Bc5 19. Qh6 Bxf2+ 20. Kxf2 Kh8 21. Nxf6 Qb6+ 22. Ke1 Ng5 23. Nxg4 Nxe4 24. Qxb6 axb6 25. Nf2) 19. Qh6, with a clear advantage to White.
12...cxd4 13. exf6 dxc3 14. fxg7

14...Qb6+
Or 14...Bc5+ 15. Kh1 Ne6 16. Nxc3 d4 17. Ne4 Be7 18. f4 Nxg7 19. b3.
15. Kh1 cxb2!
Worse is 15...Kxg7 16. bxc3 Bd6 17. Nd4.
16. Bxb2 Ng6 17. Nc3
I considered this position as clearly better to me: Black's kingside was bad, the d5-pawn was weak. However, 17. Rc1 was correct.
17...Ne7!
The only move. Now my opponent was in time trouble.

18. Nxd5?
This move is a mistake. Also after 18. f4 Bxc3! 19. Bxc3 Nf5 Black obtains good counterplay. Again 18. Rc1 is correct.
18...Nxd5 19. Qxd5

19...Re2!!
Looks dangerous, but leads to absolute equality. An excellent move!
20. Bd4 Be6!
Here Vladimir had only few minutes.
21. Bxb6 Bxd5 22. Bd4 Rd8 23. a3 Ba5 24. Rf2 Re6 25. Bb2 f6

26. f4
Black levelled.
26...Kxg7 27. Bxd5 Rxd5 28. Kg2 Bb6 29. Rc2 Bc5 30. Rf1 h5 31. Rf3

31...Kg6?
Zeitnot. 31...b6 was possible.
32. f5+
And White grabs a piece after 32...Rxf5 33. Rxf5 Kxf5 34. Rxc5+.
The conclusion. Knowledge is power, and my knowledge of the opening led to glorious victory.
Black resigned. 1-0
