Go up one level in this thread


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.

Larry.
