SEAGAMES (Mix Pair), Round 6 , 16.11.2011

Analyzed by Centaur (Hairulov + Houdini)

1. d4 d5 2. c4 e6 3. Nf3 Nf6 4. Nc3 Be7 5. e3 O-O 6. Bd3 b6 7. O-O Bb7 8. cxd5 Nxd5 9. e4 Nxc3 10. bxc3 c5 11. Be3 Nd7 Theory gave 11... cxd4 12. cxd4 Nc6 13. Rc1 Ba3 14. Rc3 Bb4 15. Rc4 Be7   

12. Qe2 Creating a potential passed pawn with 12. d5!? exd5 13. exd5 is probably stronger because white looks better if black  take the d5 pawn 13...Bxd5?! 14. Bxh7+ Kxh7 15. Qxd5  

12... Qc7 13. Rac1 Rfd8 14. Ng5 h6 15. Nh3 Bf8 16. e5 Qc6 Black has a mate threat - Qxg2++ mate  

17. Qg4? An oversight. White forfeits the advantage 17. Nf4 Is the correct move.  

 17... Nxe5!  18. dxe5 Rxd3 White lose a pawn.  

19. Nf4 Probably white main intention is to play 19. Bxh6? But this is not possible due to a tactical reply 19...Rxh3! 20. Qxh3 (20. gxh3?? Qh1# Checkmate.) 20... gxh6 with a material advantage.   

19... Rdd8 19... Rd7 is better with the idea of doubling the rook with Rad8 later.

20. f3 Qc7 21. Nh5 Qxe5 22. Bxh6 The pressure on g7 grows but black has enough defender to face it.  

22...Qf5 23. Qxf5 exf5 24. Bf4 f6 25. Rfd1 Kf7 26. Bc7 Rxd1+ 27. Rxd1 Bc6 28. c4 Rc8 29. Bg3 g5 30. Be1 f4 31. Bc3 Be7 32. Kf2 Kg6? letting the wind out of his own sails.

 33. Re1? White missed a chance to level the game with 33. Nxf6! Bxf6 34. Rd6 Rf8 35. Rxc6 Kf5 36. Rxf6+ Rxf6 37. Bxf6 Kxf6 =  

33... Rc7? again a mistake but white missed yet again  

34. g4? again white missed  34. Nxf6  Bxf6 35.Re6 Rf7 36. Rxc6

34... Kf7 Now e6 is guarded.  

35. h4 Rd7 36. hxg5 fxg5 37. Ke2? this lose a pawn.  

37...Bxf3+! 38. Kxf3 Rd3+ 39. Ke4 Rxc3 40. Kd5 Rd3+ 41. Kc6 Rd2 42. Re5 Rg2?

Black missed a tactic but...  

43. Kd7? again white failed to see the tactical move 43. Rf5+ Kg6 44. Rxf4 and white reduce black's advantage.

43... Rd2+ 43... Rxg4 might be the shorter path 44. Rxe7+ Kg6 45. Ng7 f3 and white have to give the material back to stop black's f-pawn from queening.  

44. Kc6 Rd6+ 45. Kb5 Rd2 46. Kc6 Rd6+ 47. Kb5 Re6 48. Rd5 Kg6 49. a4 a5?! I don't like this move because black will now have to passively defend her b6 pawn.

50. Rf5 Bd8 51. Rf8 Rd6 51... Bf6! and white's rook is  blocked from stopping white's f-pawn from queening and if  52. Nxf6 Rxf6 53. Rd8 f3 54. Rd1 f2 55. Rf1 Kf7 is totally lost for white.  

52. Rf5 Rd4 53. Rf8 f3!

Najiha sac her f-pawn to create stronger passed pawn on g-file.

54. Rxf3 Rxg4 55. Ng3 Rf4 56. Rd3 Rd4 57. Re3 Kf6 58. Re8 Kf7 59. Re2 Rd3 60. Ne4 Kg6 61. Kc6 g4 62. Rg2 Kf5 63. Ng3+ Kf4 64. Nh5+ Kg5 65. Ng3 Kh4 66. Ne2 g3 67. Nxg3 Sooner or later white have to give up material to stop the passed pawn.

67...Rxg3 68. Rd2 Rg8 69. Rd1 Kh3 of course black's king need to find a safe route to cross the g-file for e.g. 69... Kg3?? 70. Rg1+ Kf4 71. Rxg8  

70. Rf1 Kg2 71. Rf7 Kg3 72. Rf1 Rh8 73.Rf7

Black's king is having a minor problem crossing the f-file. One idea to solve it is with 73... Rh6+ First black defend the b6 pawn with his rook so that the bishop on d8 can move and use as a shelter for black's king to cross the f-file. 74. Kd7 Bg5 75. Kc7 Bf4+ 76. Kb7 and now black's king can cross with 'visa' 76...Kf3 77. Re7 Be3 78. Ka6 Ke2   

73...Kg474. Rf1 Kg5 75. Rf2 Rh4 76. Rf8 Rd4 Black has some problem to convert her advantage. Her bishop is passively defend the b6 pawn.  

77. Kb5 Rd6 78. Rf7 Kg6 79. Rf8 Kg7 Again black's king can cross with 79... Bf6 Black's king is planning to cross with Kf5. 80. Rb8 Bc3 81. Rxb6 Rxb6+ 82. Kxb6 Bb4 and white's a and c pawn will drop later.  

80. Rf3 Bf6 81. Re3 Kf7 82. Re1 Re6

This also win but a wiser idea is 82... Bd8 and then Re6 to let black's king to cross and guard the b6 pawn so that her bishop is free to be mobilized.  

83. Rxe6 Kxe6 84. Kxb6 Kd6 85. Kxa5 Kc6 86. Ka6 Bc3

87. Ka7 87. a5? Bb4 88. Ka7 Bxa5  

87... Kc7 Quicker is 87... Ba5 ! 88. Ka6 Bb6 89. a5 Bc7 90. Ka7 Bxa5  

88. Ka6 Kc6 89. Ka7 Ba5 90. Ka6 Bb6 91. a5 Bd8 92. Ka7 Bxa5 0-1

With this important point, Malaysia pass Indonesia in the final standing and won the Bronze medal in the mix pair category .

Malaysia Boleh!
