I changed a small part in the recap routine of crafty to what my program (crazyhouse only not normal chess) does, and maybe it works well in Crafty too. On my k6/400 at st 10 the modified crafty got 290/300 positions right at WAC compared to 288. This of course doesn't mean much at all. Your test (outputing solution time) seemed but more precise , so maybe you can give me instructions on how to run it. Or would you be willing to test my modifications if I mail them to you ? Best would be if someone was willing to run 500 test games with both versions :). Regards, Georg v. Zimmermann
