   kbob has kibitzed 184 times to chessgames   [more...]
   Apr-26-21 Botvinnik vs Pomar Salamanca, 1958
kbob: In retrospect, the anti-blockade 25. ... d4! seems best for black. Strategically, it activates the bishop. Tactically, there is 26. Rc2 Bc4 27. Qxd4 Bxe2 28. Qxc5 Rxc5 29. Rxe2 R/rxbe with equality.
   Apr-12-21 R Weinstein vs Benko, 1960
kbob: I make it better for black because he has three very active pawns to balance his material deficit. But what a pair of wimpweasels to abandon the game as a draw. Now we'll never get to know how the movie ended.
   Apr-10-21 Capablanca vs Alekhine, 1936 (replies)
kbob: Alekhine wrote a book on this tournament. From childhood I seem to recall him annotating that he started a combination, and then persisted in it, under the "hallucination" that he was winning two exchanges, but instead gave up three pieces for two rooks.
   Mar-31-21 A Sokolov vs K Spraggett, 1988
kbob: According to Karpov in his book with Beliavsky, "Caro Kann in Black and White", 10. Bd3 followed by 11. c4 is a better plan for white. For this reason Karpov offers 7. ... c5! as an improvement for Black, and he went on to win in de Firmian vs Karpov, 1990
   Mar-12-21 Gligoric vs Drasko, 1999
kbob: Gligoric calls this the "Tal Variation", characterized by d5 and the queenside fianchetto by black.
   Feb-13-21 E Inarkiev vs Ding Liren, 2014
kbob: I think I noticed one of the super programs playing the very rare 6.Nc3. Perhaps it is mere human prejudice to avoid this "retreat." Does it hinder White's c3 pawn? Does it take White longer to attack the kingside? Is any of this true and does any of it matter? We will have to stay ...
   Feb-12-21 Zhang Jundi vs Zhao Xue, 2001 (replies)
kbob: Everybody "knows", and correctly so, that the queen pawn is poison in this variation. But if you fiddle around with the engines I believe you will discover that the winning sequences are extremely difficult for a human to find over the board. Here, for example, black lures white into ...
   Feb-04-21 Miles vs Bologan, 2001 (replies)
kbob: I have heard both Carlsen and Jan Gustafsson allude to a nuance in the London System, but they did not elaborate enough for me to fully understand. I think they were referring to 4. c3 vs 4. e3, preferring the latter for white because it retains the option of switching gears with Nc3 ...
   Feb-02-21 V Babula vs J Stocek, 1996
kbob: Black missed the cute shot 16. ... Rc8 17. Qb5 Be2! 18. Be2 d3 19.Bb2 dxe2 20. Re1 Qd3 with a strong initiative.
   Sep-25-20 E Jiretorn vs J Veng, 2009
kbob: 12. ...Qa3? allowed 13. Qxa8!, winning a rook. In other games black played 12. ...Qa4 so the white queen could be trapped if it snatched the rook. Even so, that might be something white could try to start a new branch of theory.
