Rybka lost in the final. Fritz won. If this was an Olympic final Fritz won the
Gold medal and Rybak won the Silver medal. I had expected Rybka to be the
winner.

Shit happens.

Rybka is even able to lose several games (out of 200) against Doctor? 3.0.

Here an example from a 5 minute blitz game where Rybka had no chance. The
pawn-pushing moves 13.-h4 and 19.-a5 were desastrous. Rybka lost both pawns
(15.gxh4 and 26.Qxa4) without compensation - look at the increase in the
evaluation of Doctor? 3.0.

Nevertheless Rybka is my favourite engine and it flies pretty high.
