So much for >your theory I have a theory also about what might be happening. Help me test this out. Set combination to off as it would be in tournament mode. Now run the position three times in either 10 MB hash or 8 MB hash, using first AG=Off, then AG= Active and finally AG=Strong. Does Ag=off produce Bxg7, followed for a awhile by Bd3 then returns to Bxg7? Does AG=Active get Bxg7 and holds on to it? Finally, do you get the Nxb5 sequence when AG=Strong? That's what I'm getting on my machine. The trouble is the default of AG=Smart seems to just randomly choose one of the 3 options (Off,Active or Strong) with no real consistency. Can you Mark and Odell confirm this. When AG=Smart I can force a move, take it back, replay the exact same position and then get an entirely different move sequence. Are we all doing something wrong or did Ed and the beta testers miss something?
