Dec-24-09		Marmot PFL: Young Spassky has talent but must learn respect for his elders.

Dec-24-09		charlietheman: Isn't this like Kramnik not noticing mate in one

Dec-24-09		Chessical: Spassky relaxes after nicely building up an initiative. <22.d5> does not appear to be as good as it looks. <32... Nxe3> also wins after <33. Qxc7> Qd3 34. Rg2 (or <34. Qxf7+> Rg7) 34... Qxe4 35. Qxf7+ Rg7

Dec-24-09		Fusilli: <charlietheman: Isn't this like Kramnik not noticing mate in one> What game are you talking about, please? I missed that one.

Dec-24-09		Jim Bartle: Probably Deep Fritz vs Kramnik, 2006

Dec-24-09		Atking: Typical game from a strong player who stopped to play chess for a long... good strategical ideas spoils by some bad tactical moves.

Dec-24-09		patzer2: Interesting game! Spassky appears to have outplayed Korchnoi for the first 30 moves and could have maintained a small plus with 31. Ra2! Rgc8 32. Qe2! , since 32...Nxc4?? 33. Nxg4 would be winning for White. Instead he gives Korchnoi the advantage after 31. Bb4?! Nxc4 and then blunders into his elder's trap (old age and cunning defeats youth and skill) with 32. Bd6??, when after the game continuation 32...Nxd6! Black has a winning skewer combination with a nasty mate threat attached (i.e. if 34. Qxd6?? then 34...Rxc1+ 35. Kg2 Rg1#). In addition to 32...Nxd6!, Korchnoi could also have won with the surprising 32...Nxe3!! when 33. Qxc7 Qd3! (or 33. Qd2 Rxc1+ 34. Qxc1 Qd3! ) deflects the White Queen from her protection of the pawn on e3 for an overwhelming attack. P.S.: <Chessical> Although I don't think 22. d5 should have been the cause of any particular problem for Spassky, perhaps 22. dxe5 might have been a slightly better alternative.

Dec-25-09		Ulhumbrus: The course of the game suggests that Spassky lacks enough time to complete his plan of playing a N to f5 and to keep Black's N out of f4 by playing the move g3 as well. This suggests an alternative plan: to play Bxf4 and then Nf5. The earliest moment comes at move 24. Suppose White tries it then. One way for Black to lose is 24 Bxf4 gxf4 25 Nf5 Qxc3 26 Rb3 (heading for h3) 26...Qc5+ 27 Kh1 Nxe4 28 Rh3 Nf2+ 29 Rxf2 Qxf2 30 Rxh6 mate

Dec-25-09		OhioChessFan: <charlietheman: Isn't this like Kramnik not noticing mate in one> <fusilli: What game are you talking about, please? I missed that one. > Deep Fritz vs Kramnik, 2006

Dec-29-09		patzer2: At http://chessbase.com/newsdetail.asp... is some analysis of this game, which confirms my assessment of an advantage for Spassky for the first thirty moves until the time pressure mistakes at move 31 and 32.

Sep-21-10		Pygeum Lycopene: i think white had 32)d6 with maybe better results. it doesn't look as if black can double up on the c-file after that.
