"Now (May 2009), to complete the series, Rybka 2.3.2 is included with ChessOK's free interface for its training courses, Peshk@. This version was top of the rating lists for about a year until the release of Rybka 3, and even now is second only to Rybka 3 and Naum 4!! Navigate to the Peshka folder and copy the engine to whereever you keep your engines!"

just click into the yellow written word "Peshk" for download on above mentioned side
