Vasik,

I've been playing around with WinFinder and have a quick question.  If the naive
mode is only using material why are the nodes per second so low?  When I set the
mode to naive I get a nps of, at most, double the normal rate (e.g. 150 knps).
I would imagine that material only would be much faster (e.g. > 1500 nps) - any
reason why?  Is the naive mode using piece square tables or pure material only
(e.g. knight worth 3.3 pawns no matter where it's located)?

Regards,

Steve
