Are you checking the draft right, using >= rather than >> in the comparison? Etc. I'm sure I have got bug but maybe this bug is not in TT. How fast Crafty can find solution without TT. In few days I will try debug it again but I can't find reason. Today I was thinking about wrong random numbers. But now I'm sure it is OK. I will try debug it again and again....
