Bullshit -- I said this years ago, after asking a member of the DB team. Hsu just said it himself too: EeEk(* DM) kibitzes: next question: Seems like people wants to know what the exact meaning of ""12(6)" in the Deep Blue log files, can you explain this? CrazyBird(DM) kibitzes: 12(6) means 12 plies of brute force (not counting the search extensions & quiescence). CrazyBird(DM) kibitzes: 6 means the maximum hardware search depth allowed. CrazyBird(DM) kibitzes: this means that the PV could be up to 6 plies deeper before quiescence. Apparently that's not clear enough for you? The PV can be up to 6 plies _deeper_. Deeper than what? Than the software search of 12 plies, of course! Dave
