The moves were reproduced >by other programs, in 1997. You keep using this as an 'explanation'; as some type of justification, and it is not justified, nor defensible. The Programs that 'reproduced' the move did not do so under the same conditions or time control used in the match. The problem here, is that something "Strange" did happen; which completely and totaly refutes your position. No Top commercial program at the time ever played that move. Some Programs were specifically 'prohibited' from playing that move. All Kasparov had for his pregame analysis was use of these Programs. He gambled thet Deep Blue would retreat the Knight. It's as simple as that Rolf is correct >I remember Crafty finding Be4 for example, although >it took an overnight search on hardware of 1997 to find it. Then why do you keep criticizing Kasparov for believing a 'move' was strange? No Computer before had ever made those moves. There simply was >not anything that looked wrong to knowledgable observers.

Of course they never >explained who could have possibly given the machine any advice, in real-time, >when they were already playing against the strongest human around. IM Joel Benjamin, that's who. He was in fact the one that kept 'tweaking' the Program, and expanding the Opening Book for Deep Blue, based on his knowledge of Kasparov's style. That's why he was hired in the first place. >That is >often overlooked. Would I want to suggest a move to DB when playing Kasparov? >Could I? Could it possibly be a move good enough to beat him?

Because, first, DBII >>wasn't stronger than Kasparov in 1997. >So why should the fathers of the machine> >attempt to beat Kasparov right now? Why? Why? Why? Are you Naive? You can boldly ask why? Because of the FREDKIN PRIZE! That's why! You didn't know about that? Of course you did, and you deliberatly leave that out as a motive for 'why' the Team was so intent on beating Kasparov? That's shameful. The Fredkin Prize was $100,000 for the first team to build or program a computer that would defeat the World Champion in a Match! Big motivation I'd say, plus the prestige, glory, & PR that goes with it. Why didn't you mention that? >They would beat him in the nearer future. Neither you nor they knew that.

Kasparov gambled and lost. You know that. Hsu knows that. Deep Blue was not out of it's Opening Book until move 11. You know that too.
