Anyway, I agree that if any program today finds Be4 in less than a second and it was NOT programmed into the memmory, then Kasparov would have been complaining about nothing. It would be such a cheap move for computers of year 2006 and further, and the Deep Blue of 1997 must have been rather dumb, if it took a couple of minutes to come up with that move, instead of less than a second. But if it was in computers database, that's a different story. But if so, then shouldn't it have been the very first move which appears in the analysis, which it is not?
