For years Rybka has been the uncontested number one in computer chess and since its great breakthrough in 2006 the program has won with remarkable regularity one world title after the other. So that this state of affairs will continue in the future, the Rybka-team gathered around programmer Vasik Rajlich has developed a new version which is even better: „Rybka 4 plays more aggressively and more tactically“. Availabe from 28. May
During the last two years the engine has been improved in almost all areas. One major theme has been the understanding of the attack on the king. The new Deep 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 the playing style, Deep Rybka 4 logically continues the development of the past few years.
Thanks to further development in the tactical area too, the new Deep Rybka 4 will be indispensable for all those who work and analyse with chess engines. The new multiprocessor version Deep Rybka 4 calculates much faster than the single-core version: when you double the number of processors, Rybka‘s ‚speed‘ increases by a factor of 1.7! Deep Rybka 4 is delivered with the new user-friendly Fritz 12 interface and contains a database of 1.5 million games and includes CLASSIC membership for playchess.com for one year. more
