The PV can be up to 6 plies >_deeper_. Deeper than what? Than the software search of 12 plies, of course! That's exactly how I took that statement. The problem is there was another statement that lends credibility to Vincent's translation: EeEk(DM) kibitzes: kib question from ardee: Does "12(6)" mean 12 total ply or 12+6=18 total ply? This has the been source of huge arguments for years! aics% CrazyBird(DM) kibitzes: 12 total in terms of brute force. 6 is just the max partition in hardware. I still believe my original "translation" (same as yours). Unfortunately, Hsu's response is ambiguous enough that it doesn't really clear anything up for those who take a strong stance one way or the other. :) Hopefully this second q/a for programmers will happen... I'm sure this question would be top on the list. -- James > >Dave
