Hello, For years i've been wondering why Kasparov played h6?? in the last game against deep blue. It is for sure that Kasparov knew that h6?? was a bad line after Nxe6! Kasparov has said several things about this game, all crap what he says in my eyes. Latest explanation of him i heart being said on the internet was that Kasparov with his excellent memory and as a professional and young player had forgotten it and hastely played h6 thinking it would be transposition anyway. Now i found that already very unlikely. See here my big surprises when checkingout the log files of Deep Blue. I figured out that Deep Blue had thought already about moves before this! Even though some moves were from book, the moves Nxe4 and Bd3 especially there deep blue lost like 6 minutes of time somehow. Kasparov must have thought deep blue was out of book! Some moves that were made quickly by deep blue Kasparov must have thought there that they were predicted correctly by the computer, which was in fact true. the move e6 was in fact predicted correctly. Now first we can clearly deny that kasparov hastely played h6 by accident. The log file shows clearly that kasparov has thought nearly 93 seconds about making h6. Now for the average player 93 seconds in opening might mean he just drank a bit of his tea, but Kasparov who plays theorem always within a second, has given this position over a minute of thought. That can mean only one thing! Kasparov OBVIOUSLY knew both lines. He KNEW h6 was bad. He KNEW Bd6 was good. He MIGHT have considered deep blue out of book. It is very unlikely that deep blue would have played Nxe6. The score is -0.20 after the sacrafice and before that it is about +0.20, so over 0.40 pawn difference between Nxe6. Of course Nxe6 was in book. Log file clearly show that. Kasparov made Qe7 directly. Within 20 seconds. If Kasparov had forgotten the Nxe6 line he would have been in shock for at least quite some time. Kasparov was not. So kasparov WILLINGLY risked the Nxe6 line. He very likely must have thought in that 1 and a half minute before deciding to move h6 about that he already had a chance that deep blue would NOT capture at e6, after which black is fine. If deep blue WOULD capture, nah then kasparov was a piece up, like in previous games deep blue might simply allow queen exchange after which kasparov was a piece up and would win chanceless. Let's not call Kasparov too many words, but he sure was arrogant underestimating the computer in an open position. He sure was ignorant about the aggressive tuning of deep blue and he sure was naive risking Nxe6 and not even blinking when the program played it. Vincent
