1. Theres no doubt that the Rybka engine is one of the most powerful, Rybka 2 is available for download but Rybka 3, the world computer chess champion you have to pay for. Although it should not matter as Rybka 2 has been listed at a strength of about 3100 Elo. http://www.rybkachess.com/index.php?auswahl=Download+demo
