DATMO 2009, Round 2, 23.8.09

Analysed by Hairulov and Rybka 3

1. e4 g6 I wonder why Ziaur played the Modern Defense? Probably as a pyscology move against Mok who is an expert on the opening himself. From my survey on Ziaur's openings, he always played the Sicilian or the French. 2. d4 Bg7 3. Nc3 c6 4. f4 Qb6 5. Nf3 d5 6. e5 Bg4 7. a3 !? This move was not listed on Rybka opening book but probably Mok has the latest source in the Moden Defense which he understand from up,down , left and right side. 7...Nh6 8. Bd3 The idea of 7.a3 is to trap black's queen if he capture the b2 pawn as in some variation. For e.g let say after 7...Nh6 white play 8.Be3 then 8...Qxb2?? will lost to 9.Na4 trapping the queen! 8... e6 9. h3 Bxf3 10. Qxf3 Nf5 Of course not 10... Qxd4 ?? 11. Be3 trapping the queen!

11. Bxf5 gxf5 12. g4!

IM Emory Tate a GM "killer" once said..."to beat a GM you need to bite the bullet"

12...Qxd4? Better is to take the g4 pawn first with 12... fxg4 13.hxg4 Qxd4 14. Be3 Qc4 15. O-O-O c5 13. gxf5 exf5 Black pawn structure is terribly weak and white have strong threat like e5-e6 to break black's centre. 14. Be3 Qc4 15. O-O-O Bf8?! Black should have complete his development first with 15... Nd7 16. Rd4 Qc5 17. Rxd5 Qc4 18. Rd4 Qe6 19. Rhd1 Mok totaly control the game Be7 20. Qg2 Qg6 20... f6 Breaking the center is probably better. 21. Qd2 Na6 22. Rd7 Qe6 23. Rxb7 O-O

24. Qf2 Mok missed a strong combination 24. Qg2+! Kh8 25. Rxe7 ! Qxe7 26. Qxc6 And the knight on a6 will lose or black will lose material after 26...Nc7 30 Rd7! 24... Kh8 25. Rdd7 Bd8 26. Bxa7 Ba5 27. b4 27. Qd4 is safer but White's is winning anyway. 27... Qc4 28. Qd4 Qxd4 29. Bxd4 Two pawn down, double f- pawns and isolated c6 pawn- black could have resign here. c5 30. bxc5 Bxc3 31. Bxc3 Rfb8 If 31... Nxc5 32. e6+ Kg8 33. exf7+ Rxf7 34. Rxf7 Nxb7 35. Rg7+ Kf8 36. Rxb7 32. e6+ Kg8

It's mate on 6 (maximum) 33. Rxb8+ 33. exf7+ Is faster 33... Kf8 34. Be5 Rxb7 35.

Bd6+ Kg7 36. f8=Q+ Kg6 37. Qf7+ Kh6 38. Qxh7# checkmate 33... Rxb8 34. exf7+ 1-0 Black resign because he will be mate after 34...Kf8 35. Be5 Nxc5 36. Bd6+ Kg7 37. f8=Q+ Kg6 38. Qf7+ Kh6 39. Qxh7# Bravo Mok !
