Statistics.......................baseball..................betting..................amongst other things........I think that they thought that they could map out all the chess moves...........b/c while a big number............a player only has a finite number of them.........it is just that they are a large number.........when u consider all the possibilities down the line..............as in so many moves from now............

But I think they thought with a computer powerful enough and if they wrote the code well enough......from a statistical point of view...............that they could map out all the possibilities and make a perfect move..................where they would never be beaten.........esp. if u moved 1st..........u would always be a play ahead of your opponent.............in this book........the author mentions a bug in the code............in the 2nd meeting of Deep Blue and Garry K....................one which the computer scientists fixed...........between games.............the games were on different days...............it was a stop gap.....................that the computer would make a random move if it did not see a perfect winning move.............b/c in chess........u cannot pass your move...........u have to move.........so the stop gap..............was to make a random move so as it would not get stuck and not make a decision when it was Deep Blue's turn.................as a stop gap.......just in case the percentages saw no correct move..........b/c u HAVE to make a move..............but once they fixed that they thought they had made chess history b/c they had perfected chess..........in the last game in their 2nd meeting...........the computer made a move.............that Garry K.........resigned after only 17 moves or so..........unheard of from him.........

And it was a very strange move...........a sacrifice ............trading a pawn for a bishop...........a loss in material........but b/c of the positions of the pieces the computer saw an advantage, and one that if the computer didn't make a blunder that if the game were played out it would win......Garry K must have realized that........and resigned..............................

I think they figured out the code, or at least thought that they had..............................the percentages to make a perfect move.......................b/c the moves are limited...................a huge number..........when u consider the combined percentages.............down the line.......but one still finite................I think they poisoned him as well.....................they say he was visibly angry..............a furious person does not play as well.........
