94th ch-GBR, Great Yarmouth (5) 2007

Notes by Boris Schipkov

1. d4 Nf6 2. c4 g6 3. Nc3 Bg7 4. e4 d6 5. f3 O-O 6. Be3 Nbd7 7. Nh3 e5








   
8. Nf2
A rare continuation. You can read about many lines in my CD "King's Indian Saemisch System" by Boris Schipkov.
8...Nh5 9. d5 f5 10. Qc2
The good alternative is 10. exf5!? gxf5 11. Qc2 (11. g4!? fxg4 12. fxg4 Nf4 13. Qd2) 11...c5?! (11...f4 12. Bd2 Nc5) 12. O-O-O a6 13. g4 Nf4 14. gxf5 b5 15. Nfe4 Nb6 16. cxb5 (16. f6 Bxf6 17. Bxf4 exf4 18. Nxf6+ Qxf6 19. cxb5 axb5 20. Bxb5) 16...axb5 (16...Bxf5!?) 17.f6! Bxf6 18. Bxb5 (18. Bxf4!? exf4 19. Nxf6+) 18...Bg7 19. Rhg1 Bf5 20. Rg3? (20. Bc6) 20...Kh8 21. Rdg1 Ra7 with counterplay in Ward, C - Lyrberg, P, Copenhagen op 1998. Better is 13. Bd3! or 19. Bc6! Ra5 20. Nb5, or 20. Bc6, with a clear advantage to White.








   
10...Rf7
A novelty. Here 10...a6 is interesting. Black had a strong attack in Olariu, D - Rusan, P, Deva tt 1998 after 10...a5 11. O-O-O Nc5 12. a3 (12. exf5) 12... Bd7 13. b4? axb4 14. axb4 Na4 15. Nb5 f4 16. Bd2 Bf6 (16...Bxb5 17. cxb5 Ra7) 17. Kb1 Be7 18. Rc1 c5 (18...c6) 19. Nd3 Qb6 20. bxc5 Nxc5 21. Nxc5 Qxc5 22. Qb2 Ra4 23. Rc2 Rfa8. Correct is 11. exf5!? gxf5 12. g4!, and White storms on the kingside.
11. Rg1
The first player has a small edge with 11. exf5 gxf5 12. O-O-O.
11...f4 12. Bd2 c5








   
13. Qd3!
Every move must have a purpose. Now White defends the f3-pawn and intends g2-g3.
13...Bf6 14. g3 Nf8 15. O-O-O a6 16. Kb1








   
16...b5!
Black gets typical counterplay on the queenside.
17. cxb5 axb5 18. Nxb5 Qb6








   
19. Qb3!?
Jonathan bravely sacrifices his knight, but could keep a small edge with 19. Qc3.
19...c4 20. Bxc4 Qxf2 21. Nxd6








   
21...Rc7?!
Better is 21...Rfa7! 22. Nxc8 Rxc8 23. d6+ Kh8 24. gxf4 exf4 25. Bc3 Nd7 26. Rge1 Bxc3 27. Qxc3+ Ng7 28. Re2 Qc5 29. Rc2 (29. Bd5 Qxc3 30. bxc3 Ne5 31. Kb2) 29...Qh5 30. Qd4 Raa8 with real chances on a draw.
22. gxf4 exf4 23. Ne8?!
More precise is 23. Nb5 Rb8 (23...Rb7 24. Bc3 Nd7 25. Rge1 Nc5 26. Qc2 Qxc2+ 27. Kxc2) 24. Rge1 Bd7 25. a4.








   
23...Rb7?!
Steve could make a tactical blow 23...Rxc4! 24. Nxf6+ Nxf6 25. Qxc4 Qxf3, with a very wild position.
24. Nxf6+ Nxf6 25. Qc3
Or 25. Qd3 N8d7 (25...Rab8 26. Bb3) 26. d6+ (26. Bc3) 26...Kf8 27. Qc3 Rab8 28. b3.
25...Ne8
In the case of 25...Nh5 White may play on the long diagonal 26. Qe5 Kf7 27. Bc3.
26. Bxf4








   
26...Bd7 27. d6+
27. Bg3 Qa7 28. h4 with attack looks somewhat stronger.
Be6 28. Bc1 Nxd6?
Black could try 28...Rd7, though White is better too.








   
29. Rxd6!
The decisive stroke.
29...Qxg1 30. Rxe6 Nxe6 31. Bxe6+ Kf8 32. Bd5








   
32...Rxb2+
Here the bishops are far superior to the rooks.
33. Qxb2 Ra6 34. Qb8+
Black resigned. 1-0
