The GUI kicked in and declared Pro Deo the winner. I set >this to a draw of course. It's a bug in the bad-bishop (KBPK) code, I am aware of the bug since a year or 10, I can't find it :( It's hash table related, when you turn off the hash table everything is fine with bad-bishop situations. There is a cure for the problem using the MISC_71 switch, however I don't trust this switch either. In the meantine the mystery remains.... My best, Ed
