That may be so, but I can not understand how you can now it! Have you seen the
source code of either program?
In my view Rybka has some knowledge missing from all other engines, Hiarcs 10
included. I feel it has something to do with evaluation of pawn structure. It
seems to me like Rybka  can see strong free pawns comming way ahead of other
programs.
