Rybka 4: The World's Strongest Chess Engine

Rybka 4 UCI is the world champion of chess engines with a rating of 3250+ points ELO. The main developer of the program - international master Vasik Rajlich has inserted the algorithms of positional estimation into it which are as close to the chess-player's style of thinking as possible.

Rybka is a UCI chess engine, which means that you can use it with almost any modern chess user interface such as Aquarium, Chess Assistant, Shredder, Fritz, Arena, Chessbase, ChessPartner, etc.

Rybka 4 UCI uses one processor/core regardless of how many cores the hardware may have. With that limitation it also runs on all processors under the Windows operating system. If you want to take full advantage of multicore processor, look for Deep Rybka 4 UCI.

System requirements: PC, 256 MB RAM, 4GB of free disk space, Windows 10/8/7/XP/Vista.
