With only 5 >piece tables, mate in 1. With _no_ tables. Mate in 1. I as well can not reproduce this error at all. I have tried with 6,5,4,3,no tablebases, and I get mate in 1 consistantly. Someone else emailed me from the Crafty site about a week ago with a similiar postition where Slator's for some reason couldn't find the mate, yet mine had no problems. I am wondering if his beta compiler is doing something funny to the code.. Peter
