Rybka 2, the world’s strongest chess program, leads all the ranking lists clearly with a rating well above Elo 3000. Now Rybka 3 is here with a drastic improvement of at least 80 Elo points. Rybka, which translates to "little fish", is the shooting star of computer chess and the reigning world champion, having won the title at Amsterdam in 2007.
The author of Rybka, Czech/American International Master Vasik Rajlich, has implemented an extraordinary understanding of dynamic factors into his program. This often results in long-term pawn or exchange sacrifices and an active positional playing style resembling human chess. Rybka scores well in all types of situations but dominates especially in asymmetric positions which arise for example in Sicilian Defences. The success of the program stems from dedicated team work: IM Iweta Rajlich is the main tester; Jeroen Noomen contributes opening theory and tournament preparation; IM Larry Kaufmann develops positional evaluation algorithms.
Today the main use of chess software is in interactive analysis. Rybka’s superior playing strength helps you to quickly assess a position. But analysis with Rybka 3 is much more than evaluations and best moves. In the user interface designed by ChessBase, Rybka 3 introduces several ground-breaking new analysis features: Rybka 3 with ChessBase Interface
Monte Carlo Analysis yields precise evaluations by playing thousands of ultra fast games in a few minutes in a given position.
Sampled Search gives detailed information about the search process, showing scores and alternative moves in the main line. This is helpful when the program searches for a long time in one position. Singular Moves are annotated graphically. This highlights situations where only one clearly best move exists.
Look for win: whenever you feel that there should be a forced win in a position you can explicitly ask for it. Rybka then searches for a decisive move, considerably faster than in normal analysis.
Persistent Hash: Rybka can save its hash tables between analysis sessions to preserve valuable information already accumulated in the search tree.
