All Rybka at contemp =0 looks like R3D does the best against both SF and Iv.
Iv has serious problems with SF!
Rybka's blind bishop bug/bishop underpromotion incapability is an absolute disgrace at this point -- beginner to average skill chess players will not be able to spot bad eval due to blind bishop bug ---
The blind bishop turns up with Rybka 's absurd evaluation in quite a few games
