First quotation (from Kasparov's site): "During the press-conference Kasparov said that 13...b5? was probably the decisive mistake." > >I also see no analysis of alternative to Rae8. Do you mean an engine's analysis? By two humans it is done. Second quotation (from Kasparov's express analysis): "17...Rae8 From the human’s standpoint this move looks paradoxical. On the other hand, from the machine’s angle it is quite logical. Since the e5-pawn was under attack, the computer chose the lesser of two evils. After 17...Rad8 18.Nxe5 Nxe5 19.Qxe5 Ba8 20.f3 Black is helpless. Its pieces are poorly placed; there is no compensation for the pawn. By the way, I would not say that this exchange sacrifice is absolutely innocuous. A human might get confused in such a situation." And third quotation (from Shipov's in-depth analysis): "17...Rae8 Sacrificing the exchange! The variations given below illustrate Black's problems: 17...Rfd8? 18.Nxf7! Kxf7 19.Rxd7+! Rxd7 - two decoying sacrifices helped the white knight to win the Grand Prix! 20.Nxe5+! - a triple fork! The problems for Black are in the line 17...Nf4 18.Bxf4! exf4 19.Nf5! Black faces an unpleasant alternative - either get checkmated on g7, or give up his queen after the fork on e7. More reasonable was 17...Rad8 with the idea of sacrificing another pawn for the initiative after 18.Nxe5 Nxe5 19.Qxe5 c3! Actually this line is in Junior's "spirit". I guess that Garry would not have captured on e5. The solid move 18.Rd2! followed by doubling the rooks on the d-file looks more practical. White has very stong pressure! Finally, Black could have played 17...Rab8!? in the hope of putting some pressure on b2." >I am not sure if white is winning so easily and I suspect that black will get >points in 120/40 between the top engines. Engines and humans are so different things :-) Best regards, Igor
