I don't run dos/windows stuff here, so have no way to test this, and I really don't have time to do so. Crafty might legitimately lose 41-9 vs fritz for all I know, because I _never_ test against other programs on equal hardware. That has been what 'crafty' is all about for the last year or so, using an 'unequal hardware advantage (multiple cpus)'... > Of course Crafty >is playing without it's opening book.

Getting a 'good start' is half of the battle in these games...
