|Jul-13-09|| ||rwbean: With the help of Rybka 3 (verified with Glaurung 2.2), I found another variation that was misevaluated by Kasparov (in his 2000 book about the game) and Krush (in her analysis during the game):|
29 ... b4 30. h6 Qc2 31. Bxf4 Nd8 32. Qh5 Bxf4 33. h7 Be5 34. Qxe5 dxe5 35. h8=Q Nc6 36. Qh3+ and now 36 ... e6 37. Qe3 Nd4 draws:
if 38. Re1 Qf5, or 38. Qxe5 Ne2+ 39. Kh1 b3.

It might be a little strong to say that <27.Qf7> was a 'big error'. Many engines (except Houdini) had it as the top move at lower plies. Although the engines seem to agree that <27.h4> had a higher evaluation at deeper plies, it's quite likely Kasparov saw h4 but decided to play his Queen for some reason.

That was a great psych move by GK! Recall, this was before arrival of strong engines..
None of the experts on the World team could see it coming, and it resulted most likely in total chaos at the World team's message board.
Always play the man! :)
|Oct-11-10|| ||rwbean: Rybka 4 actually changes its mind from 35. Kg2 to 35. Kh1 at 28 ply (with 8-core i7 at 2.8 GHz, after about 12 hours):|
info depth 31 score cp 142 time 75866110 nodes 30655562899 nps 404074 pv g1h1 b4b3
There doesn't seem to be much change in the score.
However for 27. h4, it's the difference between an eval of about +125 and 0, because Black can draw with 29 ... b4 in the game. It needs more investigation, I'm writing about it at elvumgar.fea.st.

|Jan-24-11|| ||Kinghunt: <Tigranny: What was the plan with 54.b4? And couldn't Black perpetually check White after 62.g7?>|
The idea is to divert the white queen from the f file in order to allow black to give checks down it. It turns out to be a mistaken idea that turns an objectively drawn position into a position objectively won for white, but it takes immense amounts of analysis to show this.
And no, black cannot force a perpetual check after 62. g7. One winning line goes 62...Qc6+ 63. Kg5 Qd5+ 64. Qf5 Qg2+ 65. Qg4 Qd5+ 66. Kh4 Qh1+ 67. Kg3 Qg1+ 68. Kf4 Qe3+ 69. Kf5 Qd3+ 70. Kg5 and black has no more checks. It's a very deep win, and few would have resigned here over the board, but this was a correspondence game, and both sides could see the forced win (Kasparov found it first, then announced it).

|Jan-27-11|| ||Tigranny: Sorry about my error Kinghunt.|
Let's not underestimate just how good the World played this game. Kasparov was barely able to squeak out a win against us.
We don't even have to consider the possibility of voting fraud or e-mail scandals. Kasparov's own words tell just how great we played.
<"After the game Kasparov shocked many people on the MSN forum, which was kept open after multiple requests, by announcing he had been reading the World Team strategy board during the game">
He admitted he needed to read our analysis in order to compete with us!
|Dec-26-13|| ||alexh0264: @Kinghunt jan-24-11 : I don't understand why black has no more checks after your play 70: why not 70. Kg5 Qd2 ? Or 70. Kg5 Qb5?|
|Jul-24-14|| ||IFNB: Wow, I never knew Kasparov pulled a Bill Belichick in this game. Decreases my appreciation of it just a tad.|
|Aug-04-14|| ||rickycota: <DPLeo> Play yourself against Kasparov and then talk, just don't use Engines|
|Aug-04-14|| ||AylerKupp: <rikycota> What's your point? You don't think that <DPLeo> and the other members of the team should be proud of themselves because they almost held the greatest player of all time to a draw and only lost at the very end? And don't forget, Kasparov was also using both engines and assistants in this game.|
What do you think it would prove if <DPLeo> or anyone else at this site played Kasparov one-on-one without the benefit of engine support? That Kasparov is a better player? Well, duh.
|Aug-05-14|| ||OhioChessFan: <"After the game Kasparov shocked many people on the MSN forum, which was kept open after multiple requests, by announcing he had been reading the World Team strategy board during the game"> |
Yes, an outrageous ethical failure on Kasparov's part. I don't know what to think of the fact he admitted it.
|Oct-22-14|| ||SpiritedReposte: I love a game that is so close instead of it being over when you are promoting a pawn, it is just the beginning of a second act.|
|Jan-08-15|| ||GoldenBird: Eww 11...Qxe4|

A real blunder by GK. He could have tried to make it fair, who would vote for someone who does this?
