I never used Crafty for this purpose. I used it only for playing chess. Great program! But I was very interested to know why many of programs that I used around 4 eyars ago crashed on positions, even every modest compared with the last one. Now I only have some guessing about what it could be. Maybe some programs use some look-up tables that is the beginning for all limitations. Maybe number of moves was limited for each ply, taking in consideration that DOS was very restrictive system. I just don't know... Leonid.
