You might be right about the Qe7 move is not optimal. Kasparov played it however within 20 seconds. big question is WHY did kasparov play Qe7 so fast? Seirawan describes that Nxe6 came as a big shock to Kasparov. WELL I DO NOT BELIEVE THAT. Perhaps the only shock was that he fell back into the deep blue book. I can't understand why someone playing kasparov's own invented attack (5.Ng5) which he prepared against karpov VERY well, so he knew everything. I am still thinking that he simply guessed there was already a chance deep blue was out of book and would probably not play Nxe6 and then have a bad position. He was too convinced probably, that when nxe6 came, it was a big shock. It seems you are right however that Qe7 is a big mistake and that Ke7 is fxe6 is better. Note that it is a big misunderstanding that Deep Blue thought after that 10.Bg6 leaded to big advantage for white. Last PV move is -10, so that's obviously -10/128 or something like -0.08 pawns disadvantage for white approaching zero rapidly when playing Bg6, obviously Bg6 was a book move (but of course fxe6 was pondered correctly. So the big stories that deep blue already saw white winning here are not true. Deep Blue goes very slowly up in score when position gets slowly open. It never comes over half a pawn up for white even when game is already long over. Only after 16...Bc6?? deep blue goes up in score and goes up to just over a pawn up. the stories about the excellent working search of deep blue isn't truth, nor is the evaluation of it that well here. >one was against lautie (sorry for not knowing to spell his name correctly)when >he sacrificed a piece and did not remember a move in his notenook and another >case was in the olimpiad when he lost something like a rook for a knight because >he did not remember the order of moves and had to fight for a draw. > >kasparov is a human and his memory is not perfect. > >He can forget. >I do not believe that he forgot the theory in this case bevause it was too early >in the opening and the only other possibility if it was not a bad decision is >that he simply did a mistake because of thinking of his next move. > >The time per move say nothing because it is possible that kasparov was not near >the board in the time that the computer played. > >We need to hear from people who watched the game to know what happened. > >Uri
