If it is searching way less deeply than any other program, then this evaluation is already a major problem. How can someone handle positional things *that* bad? >es a move.

Either IBM is lying on its screen, or perhaps it's really as bad as i'm telling for years? it's just playing with its pieces, some things it seems to understand, like that a rook in the corner can be bad when its closed in, see ferret - fritz of today where fritz got after some bad moves (personally i'm still considering fritz was won after the opening) got a rook closed in the corner. it seems this deep blue junior knows this. So even if it thinks for say 15 seconds, and practically a few seconds, then still there is a lot to explain. Greetings, Vincent Greetings, Vincent
