15th Northern Virginia Open (5)

Oladapo Adu: My last game against IM Enkhbat was interesting. I prepared the line I played just immediately finishing the 4th round. The game stemmed from two games GM Daniel Stellwagen 2616 vs. GM Berkes 2645 Paks 2008 and also the game Abdulov 2318 vs. Khamrakulov 2554 world junior 2008. I was on a white side of a Caro Kahn Defense. After 20.Nf5 followed by 21.Rdg1, I thought white should have a winning attack for the pawn. I sacrificed a knight on g6 and the pawn wedge set up a mating attack that could not be parried unless with heavy loss of material.

1. e4 c6 2. d4 d5 3. Nc3 dxe4 4. Nxe4 Bf5 5. Ng3 Bg6 6. h4 h6 7. Nf3 Nd7 8. h5 Bh7 9. Bd3 Bxd3 10. Qxd3

So far this is mainline theory that has been seen in countless games. Somewhere black fell off course and faced a crushing attack. 10... e6 11. Bd2 Ngf6 12. O-O-O Be7 13. Qe2 O-O 14. Nf1 c5 15. g4 cxd4 16. g5! The sharpest move. 16... hxg5 17. Bxg5 17. h6!? 17... Qa5 18. Kb1 e5 19. Ng3 Rfe8 20. Nf5 Bf8 21. Rdg1 Adu's position looks menacing and even against strong players, these attacks play themselves. 21... Kh8 It is not reassuring to play the king what seems to be in the line of fire. 22. N3h4 22. Bxf6! Nxf6 23. h6 g6 24. Ng5! with a strong attack. 22... e4 23. Ng6+!

23... fxg6 23... Kg8 24. Nxd4 fxg6 25. hxg6 Qd5 seems to hold the diagonal, but white has compensation for the piece. 26. Qe3 Bc5 27. Bxf6 Nxf6 28. Rg5 Re5 (28... Qxd4 29. Qb3+) 29. Qh3 Kf8 30. Rxe5 Qxe5 31. Qb3! 24. hxg6+ Kg8 25. Bxf6 Qxf5

26. Rg5! 1-0 [Shabazz]
