Despite beating firebird in 16 game mini-match (an amazing fluke due to the particular opening positions and luck) Rybka 3 still is second.

[frcha]

The 8 positions are below.. The idea was to actually let the programs play the openings from 1 or 2 plies without any aid at all, but I ended up going a few moves deeper. I think Rybka 3 was strong in the nimzo, french, and catalian. I will probably try a heads up match between R3 and FB using the openings that r3 did well in.
