The one it plays will be the one it searched first (in other words, it depends on the internal move ordering). Sorry that isn't a very good answer. <snip> >Please think about this, and comment further if you will. >Thanks, >CY If you are a human, sure it is interesting tool for analysis. If the computer has some sacrifice that is "just below the horizon" then maybe it would work out if you played down it a bit. Or, perhaps you have a move you want to play, and you are curious about the score relative to the best move. No one is disputing this, although you should be aware that generating multiple best moves slows it down a LOT. Shredder would probably have gone two ply deeper in 1-best-move mode. However, in terms of the computer "getting" a move - it doesn't count, for the reasons I outlined in my last post. You are arguing a point that, while correct, doesn't affect the real question, or at least are using words that don't fit with the accepted usage here. anthony P.S. The true eval is the eval of the best move (that is the assumption of alpha-beta, that both sides play the optimum move).
