Thanks Vincent and Michel :) I found Crafty and ran it... I found the bug (sheepish Grin) in my program and ran to ply 7... Sure enough the 4,865,609 was the correct number. Thanks for posting it Vincent. I only need to add castleing and pawn promotion to have my move generation completed. Meanwhile... (This is for you Robert) :) Crafty reports a negative number when I try to use perft at ply 7. Would it be a simple thing to extend Crafty's perft function to display larger numbers? I need to add castleing code to my program and need another target to shoot for.
