NM Ilya Krasik – BOS (2276)

US Chess League – Week 4

King’s Indian, Sämisch (E81)

1. d4 Nf6 2. c4 g6 3. Nc3 Bg7 4. e4 d6 5. f3 0-0 6. Be3 Nbd7 7. Nh3 c5 8. d5 Ne5 9. Nf2 a6 10. Be2 h5

I think a6 and h5 are somewhat inconsistent: if you play a6 you have to be ready to play b5 a la the Benko. Plus, h5 seriously weakens the g6 square.

11. 0-0 e6 12. Bg5 Qe8

12... exd5? 13. Nxd5 Re8 (13... Ned7 14. e5 Nxe5 15. Ne4 Ned7 16. Qe1 Re8 17. Qh4+-) 14. f4 Nc6 15. e5 dxe5 16. Ne4+- and the pin decides.

13. f4

13. Re1 or 13. Qd2 are also possible.

13... Neg4 14. Nxg4

Computers denounce this move but I had a concrete idea based around the e5 pawn sac.

14... Nxg4 15. Bxg4 hxg4 

16. e5!? dxe5

16... exd5 17. Nxd5+- with unstoppable threats of Nc7, Ne7 and Nf6.

17. fxe5 Bxe5

17... exd5 18. Re1! dxc4 19. Nd5 Be6 20. Nf6+ Bxf6 21. Bxf6 and Black’s king is in trouble.

18. Qxg4 exd5 19. Qh4

The position I envisioned when I planned e5. White's attack is very dangerous.

19... Bd4+ 20. Kh1 f6 21. Rae1

21. Rxf6 Bxf6 22. Bxf6 Rxf6 23. Qxf6 is considered best by the engine but the game move is just as decisive.

21... Qf7

21... fxg5 22. Rxe8+- is the point and Black doesn’t have time to take the queen.

22. Bh6 Re8

22... Bxc3 23. bxc3 Rd8 (23... Be6 24. Rf3 dxc4 25. Bxf8 Rxf8 26. Rfe3 Re8 27. Qg3 Kg7 28. Qd6+-) 24. Rxf6+-

23. Rxe8+ Qxe8 24. Nxd5 Qd8 25. Qe4! Kh7 26. Ne7 Bf5 27. Rxf5!

27. Qh4 Bf2 doesn’t work due to 28. g3! (28. Qxf2?? Qxe7=)

27... Kxh6 28. Rxf6 Qe8 29. Rxg6+ Kh7 30. Qh4#
