| Jan-02-10 | | ajile: Nice game by Kamsky. Note how he takes advantage of Black's 5..Ne7 by pushing his h pawn. The resulting liquidation of pawns on the k-side clearly favored White. |

Here, black immobilized his own rook with <34...d5??>, where white trapped it with the simple 35.Ne6. The black rook has nowhere to go. Black goes down the exchange, and white, interestingly, gives it back for a couple pawns and simplification. The 3-passed-pawn advantage should be easily decisive. |

 | | notyetagm: http://www.thechessmind.net/blog/20... <He was caught there by Gata Kamsky, who defeated Baadur Jobava on the White side of a somewhat offbeat Botvinnik System English. (It was unusual, but it's strange that whatever program Mark Crowther of TWIC is using labels it "Dutch, QI and KID Systems".) Whatever it was, it led to a position where Kamsky was able to obtain an advantage by taking control of the light squares. Jobava's 19...a6 may have been inaccurate, as after 20.Bh3 Bxh3 21.Nxh3 (preventing ...f5) 21...Re5 22.Nf4 Rhe8 22.Nd5 White was clearly better. Black could achieve ...f5 before it would be forever too late, or he could protect his h-pawn, but not both. <<<White's advantage was significant but not decisive, however, until the blunder (probably in time trouble) 34...d5, losing the exchange to 35.Ne6.>>>> |

| Jan-03-10 | | chessic eric: Note that 34...Rxc1+ doesn't pickup two pieces for the rook after 35.Rxc1,Qxf4 36.Qg2 when there is no way to defend the knight (36...d5 37.Qxd5,Qf6 38.Qxb5+,Kc8 39.Rxc6  (Qxc6??,Qxb2#)). |

 | | HeMateMe: Pretty bold opening, I wonder if black should have focused more on picking up the weak h pawn, instead of trying to attack in the center. |
