WAC, BK, BT2xxx - what it is?

I can't say nothing about GNU, Crafty and so like since I don't know how to find
their core logic speed when we speek about "positional move". If you speak about
finding mate then mine should lead or be between the leading at least.

When I tried my "raw speed" of "positional logic" against games such as Genius
4, Hiarcs 7.32 and Rebel 10 (if there are just no some extra mistakes that are
all the time possible) mine begin loosing in time only starting with ply 10.
Since I have the impression that mine loose around 8 or ten times speed before
it reach 10 ply deep search (positional logic) I am so eager to know where mine
goes wrong.

NPS in some indirect way says that my numbers about general speed in positional
logic is right.
