Deep Rybka 3 (Multi-Processor Version)

Deep Rybka 3 is the newest version of Rybka and is produced by Chessbase. Rybka, which translates to little fish, is the shooting star of computer chess and the reigning world champion, having won its title in Amsterdam in 2007. Rybka 3 is one of the hottest selling playing programs we have ever carried.

Deep Rybka 3 has a drastic improvement of at least 80 Elo points over Rybka 2, the worlds strongest chess program to that point, which had ratings well above Elo 3000.
 
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 especially dominates in asymmetric positions which arise, such as from Sicilian systems.
 
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 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:
  • 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 indicates 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: Deep Rybka can save its hash tables between analysis sessions to preserve valuable information already accumulated in the search tree.
Includes a database of one million games and one year of access to the chess server Playchess.com.
