Comment: Rybka 1.0 beta is the strongest free uci engine (elo = 2809 )

The Rybka 2.1 c mp commercial is 200 elo stronger than the Rybka 1.0 beta and stand like the strongest commercial Engine . It almost won all tournament last 9 months (Pal/CSS, Leiden, Padeborn, CCT8, IPCCC ...)

Rybka 1.0 is taking part to the golden league like free uci engine.

Thanks to IM Vasik Rajlich to offer to this site and all chess engine fans the Free demo 2.1c too .

"It is identical to Rybka 2.1, with the exception that the analysis is
always cut off after approximately 1 second."
