Oct-28-09 Svidler vs Vallejo-Pons, 2004

soberknight: Should be "pwned" by Pons! :)

Oct-21-09 Nakamura vs S Muhammad, 2004

soberknight: <The important question is why don't strong masters make blunders like that against me???? AAAARGHHHH!> I think the more important question is, when inexperienced amateurs do make those blunders against me, why do I fail to notice? :)

Jun-01-09 Spassky vs Fischer, 1992

soberknight: Um, I don't get the pun. I know Fischer and Spassky were old at the time. It's a very interesting game.

Jun-01-09 V Gashimov vs Kramnik, 2009

soberknight: Oops! There goes the rook. :) I solved it.

May-07-09 A Yurgis vs Botvinnik, 1931

soberknight: I thought it was Bc5. I didn't even think of Rc4. It's one of those things where you need to practice looking for moves that 99% of the time are unplayable, by looking at the context, in this case connected passed pawns that can beat a lone rook. My thinking was similar, but not

May-07-09 Alison vs Fink, 1979

soberknight: Well, I was wondering why not 14...Qxf5 also. It looks obvious. 15. Rxf4 is automatic, threatens Rxg4 taking back one of the pieces, and Rxf7+ when the queen moves. I'm shortsighted in chess terms, so I can't see beyond that without taking out a chessboard and doing a proper 20 ...

May-06-09 S Paschmann vs Kurschat, 1986

soberknight: Very similar to another game where Black plays 8...Na6 but makes the 9...Rb8 blunder, forgetting why he put the knight there in the first place. Look in "similar games."

May-06-09 B Bartsch vs Jennen, 1948

soberknight: Wow, that's a beautiful mate!

May-06-09 E J Diemer vs Toth, 1948

soberknight: Oops! In E J Diemer vs H Halosar, 1934 Halosar resigned after Rc8 Qxa6 on the last move. Rb8 puts Black out of his misery more definitively. 9...Qe4 is probably the best choice.

Apr-24-09 Huebner vs Korchnoi, 1987

soberknight: didn't see e6.
