You're right that you'll not know how far you have to search, but you do know that you'll have to search (at most) 10 ply. (Or replace 10 with any other arbitrary number). If we decide before hand that searching 10 ply can be done reasonably quickly, then this is a space v time trade off... Since we know the space 7-man tb's take is huge, trade some time to make them smaller. Or perhaps you mean when converting to TB play is on the horizon, and you are not solidly within them yet? Then having a bitbase (right term?) like you describe would help. I was only considering the need to know how to continue the line once you were into TB territory. Guess the horizon portion is probably more important... --Bill
