The new Houdini 4 contains many evaluation and search improvements in all phases of the game and is about 50 Elo stronger than its predecessor. The improved strength means that Houdini 4 nearly doubles the chess performance of your PC for game analysis and match play.
A major feature is the support of the new 6-men Syzygy table bases. Houdini 4 has been extensively tuned for this state-of-the-art end game table base system and will provide optimum precision and strength in the late endgame at any time control and with any number of cores. While we strongly recommend using the 6-men Syzygy tables, Houdini 4 continues to support Nalimov and Gaviota table bases.
Houdini 4 maintains and improves on all the goodies that made previous Houdini versions the preferred analysis tool for many chess players. The Tactical Mode of Houdini 4 will find more solutions and provide faster solution times in tactical test suites than any other engine. Persistent Hash and Learning are essential tools for storing your valuable analysis results for future use. Houdini's very efficient multi-PV analysis and its support for Chess960 a.k.a. Fischer Random Chess remain the reference in the industry.
