   Thumbtack2007 has kibitzed 15 times to chessgames   [more...]
   Jul-22-14 M Sharif vs Kasparov, 1988 (replies)
Thumbtack2007: According to the heading today, it was a simultaneous exhibition. Still, beating K in a simul definitely deserves a gold star.

Thumbtack2007: Prettiest smothered mate I've ever seen (well, almost completely smothered). And the triple pin is indeed a gem.
   Jul-12-14 Potkin vs Kamsky, 2010 (replies)
Thumbtack2007: <funkenstein> 16.Qc2 is better, but White has an inferior position after 12.Qd2. 12.Rd1 is better, but we get a sporty game after 12..Nb4 13.Qb1 Nxe4 14.Nxe4 Bxa2 15.Qc1 Bd5. Even position, but lots of play on both sides. I would have liked to see the continuation on ...

Thumbtack2007: Yes, no mating combination is there, but a Queen sac works with the passed pawns. As an aside, I've always liked the Cambridge Springs variation.
   Oct-03-12 J Gustafsson vs Naiditsch, 2012
Thumbtack2007: After further analysis, I conclude that it is not possible to lock up the pawns, and eventually the rooks can be joined together to devastating effect. So, unless you hoped that Black would make a mistake, a resignation was appropriate.
   Oct-21-11 H Bouwmeester vs Botvinnik, 1958 (replies)
Thumbtack2007: I missed the move. But after 27...Rb1 28 Rc2 RxQ 29 Rfxc1, even though White is down a Queen for a rook, he can still put up quite a fight.
   Oct-04-11 Bosboom-Lanchava vs M Kursova, 2007
Thumbtack2007: I agree that time pressure must have been to blame for Black's 39 .. Qxf5 blunder which throws away a winning position; I also agree that 39 .. Qxc7 is far superior and that if Black had played it, she would have won the game. It also seems to me that the game was about even ...
   Sep-23-11 M Yudovich Sr. vs Ragozin, 1937 (replies)
Thumbtack2007: If looking to see if a mate combination is there, 32. Nf5 is one of the first things you check. 32. .. NxQ 33. NxQ eliminates the mate, but leaves White with a one piece advantage which quickly becomes a one piece and two pawn advantage.
   Sep-17-11 A Geller vs M S Tseitlin, 1987 (replies)
Thumbtack2007: White's 21 Na5 is too aggressive and seems to lead to disaster. After 21. fxg3 Rxe3, White's position is not great, but looks like it holds for a draw (Stockfish 2.1.1 confirmed this assessment, obtaining a draw by repetition many moves later).
   Sep-12-11 Timman vs J Vogel, 1974 (replies)
Thumbtack2007: Stockfish 2.1.1 immediately selected 38. f5 Kg7 39. Kf2 exf5 40. Ke3 Kf7, etc. The king side pawns disappear, and finally White gets a Q,P against Q end game, not the easiest one to carry out (as noted by <stst>, it takes a LOT of patience).
