description & information:
The "Little Fish" that's made a BIG SPLASH in the Chess World!
For years Rybka (literally, the “little fish”) has been the uncontested number one in computer chess. Since its great breakthrough in 2006, the program has won with remarkable regularity one world title after another. So that this state of affairs will continue in the future, the Rybka-team has gathered around programmer Vasik Rajlich and developed a new version which is even better: Rybka 4 plays both more aggressively and more tactically! During the last two years, the engine has been improved in almost all areas. One major theme has been its understanding of the attack on the king. The new Rybka 4 is in this case more precise and reliable than its predecessor. At the same time, the search function now operates more quickly and efficiently, and the evaluation function delivers even more spot-on judgments. As for its playing style, Rybka 4 logically continues the developments of the past few years.

Thanks to further progress in the tactical arena, the new Rybka 4 will be indispensable for all those who work and analyze with chess engines. Rybka 4 is delivered with the new user-friendly Fritz 12 interface and contains a database of 1.5 million games, and included with purchase is one year of CLASSIC membership for playchess.com.
