Probably it was solved by selective search and not by brute force. But even by
selective search, I would like to know how much time it took. One second is just
too tiny moment to see what it exactly say. It could be less or more then one
second. If you could, please, try this position with same chess program on slow
computer. If you could find 486 50Mhz, it will be ideal. I just tried with my
program (llchess) this position on 486 50Mhz laptop. Time for selective search
was 0.33 sec. Mate was found in 7 moves.

Leonid.
