Chess Assistant 13 with Houdini 3 is a unique tool for managing chess games and databases, playing chess online, analyzing games, or playing chess against the computer.
The Starter Package includes the best chess engine – Houdini 3 (rating 3350 by CCRL), Chess opening Encyclopedia 2012, a powerful search system, a unique Tree mode, databases of millions of games (as of October 1, 2012) that can be updated with 2000 new games each week at www.chessok.com, etc.
The new Houdini 3 contains many evaluation and search improvements in all phases of the game and is about 50 Elo stronger than its predecessor Houdini 2. The opening improvements are mostly related to piece activity and space management and are convincingly demonstrated by the progress in Fischer Random Chess for which Houdini 3 has become about 75 Elo stronger. In the middle game Houdini 3 has significant enhancements for recognizing pieces with limited mobility and in king-side safety. In end games Houdini 3 will seek deeper and solve more positions than before.
Three Long Time Control Challenges
As a serious challenge for the new Houdini 3, last month three long matches between the Houdini 3 Beta version and other top engines (Houdini 2.0c, Stockfish 2.3.1 and Komodo 5) were played. Each match consisted of 120 games at 90 min + 30 sec/move, starting from 60 Noomen opening positions played from both sides.
Over-all result: Houdini 3 scored 62% (Perf: +81 Elo ± 24 Elo) against the average of Houdini 2.0c, Komodo 5 and Stockfish 2.3.1.
The final Houdini 3 Release version is even slightly stronger than the Beta version used in these matches.
In the new Tactical Mode Houdini 3 will adapt its search strategy to prefer tactical solutions rather than positional moves in the root position. Some clever search tricks transform the engine into the most proficient tactical position solver ever. In tactical test suites the Tactical Mode will find more solutions and provide significantly faster solution times.
The Accelerated Principal Variation Search or “Smart Fail-High” is especially useful in very deep analysis when a different move becomes best at very high search depth. Houdini 3 will apply an automatic depth reduction that often speeds up finding the Principal Variation by a factor of 5 to 10.
Chess Opening Encyclopedia 2012 includes rich theoretical material on all the openings, with key opening positions provided with more than 8000 annotations by GM Kalinin and 40 million evaluations by the strongest engines. The detailed key system for all openings can be edited to suit your needs.
Chess Assistant 13 includes the ChessOK Playing Zone interface and twelve months of free access (1 year membership) to the Playing Zone, providing you with full access to its various features, including tournament participation, lecture creation and game analysis in groups.
Sergey Rublevsky, Russian Chess Champion: “I have been using Chess Assistant with great pleasure for more than 10 years already.”
