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. ----------------------------------------------------------------------------------------------------------------------- OK, some questions: 1. If 12(6) means 12 plies total, with 6 done in hardware, how do you reconcile that _last_ sentence above (the PV could be up to 6 plies _deeper_ before quiescence). Deeper than what? Only possible answer is deeper than 12 plies. 2. If 12(6) means 12 plies total, with 6 in hardware, what does 4(5) mean? 4 plies total with 5 done in hardware? Which means the SP hardware does _no_ searching and that _everything_ (and then some it seems) is done by the hardware chess chips? Neither of those matches what he says above. I read his explanation of 12(6) as "12 plies of brute force, up to 6 more plies of hardware search [which is not brute-force as he has explained elsewhere, because of the forward pruning they were doing]". I don't see any _other_ way to take the above, which came _directly_ from the answer he gave... So I won't say 12(6) means 18 plies, but it _clearly_ means "more than 12 plies, and up to 18 plies"... At least that has to be true... Otherwise you can't reconcile _anything_ with the log files and the 4(5) type notation...
