This response look to me as excellent, if search is done by brute force. It is
very close to mine or better. My last version found mate by brute force in 11
min 24 sec. My previous had worst branching factor but, to my surprise, solved
position in 2 min 42 sec. Celeron 600Mhz. No hash.

Cheers,
Leonid.
