There are 2 versions of Houdini, they both include the exact same software with the exact same features. This version (Pro) is intended for users that have more than 6 processor cores (up to 32 cores) and need up to 256gb of hash memory. If you need support for 6 cores or less  and/or up to 4gb of hash memory you will need the Standard verison, which is available here.  

Houdini 4 Pro is the unquestionable number one! The program, written by the Belgian Robert Houdart, is known for finding tricks and resources in positions that just can’t be cracked by other engines. Now, with the release of its latest incarnation, Houdini 4, the engine has been improved significantly across the board. Its 50 Elo point boost in playing strength represents practically double the performance in analysis and engine matches.

A significant element of the new version is its support of the new Syzygy tablebases, which represent the complete analysis of all endgames up to 6 pieces.* Indeed, Houdini 4 was developed with compatibility in mind and has been tuned to work with this ultramodern tablebase format to deliver the optimum in terms of precision and strength in the endgame.

Houdini 4 also offers all the virtues and elements that made its predecessor the most popular analysis program in the chess world, but now also uses extremely precise evaluation functions that directly correlate with the engine’s expectations of winning a particular position. As well as this, the improved “tactics mode” now makes Houdini 4 the best tactical puzzle solver ever.

Houdini 4 comes with the latest Deep Fritz 14 GUI and also offers the complete range of training features and analysis features included as standard in Deep Fritz 14.

This software is for Windows Only. It will work fine on a Mac or Linux in a virtual box solution such a VMWare or Parallels

Included on the DVD:

  • Houdini 4 engine. The engine can support up to 32 processor cores and 256 GB of hash memory
  • The new Deep Fritz 64-bit program interface, (also works with 32 bit computers interface)

New Features

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 uses calibrated evaluations in which engine scores correlate directly with the win expectancy in the position. A 1.00 pawn advantage gives a 80% chance of winning the game against an equal opponent at blitz time control. At 2.00 the engine will win 95% of the time, and at 3.00 about 99% of the time. If the advantage is 0.50, expect to win nearly 50% of the time.

Accompanying the new engine is a giant hand-made opening book by openings expert and openings book designer: Alexander Kure, with over four million positions. This opening book is not a generic tree, and includes carefully thought out evaluations as well as original analysis.

Optimized for Windows 8.1: the 64-bit program interface of Houdini 4 runs faster and more fluidly on the latest versions of Windows. Naturally, the new version retains all of the well-known playing, training and analysis functions that have made it the most popular chess program in the world.

Premium Playchess

Houdini 4  includes a free six-month Premium Membership to the Playchess.com server allowing you to tune in to exciting live commentary of world-class tournaments, or take part in training sessions with frontrunner coaches such as Grandmaster Daniel King, Klaus Bischoff, Maurice Ashley, Dr. Karsten Müller and many more.

Let’s Check

Houdini 4 also brings all the powerful new functions introduced and fine-tuned in the last couple of years. Only the best is good enough. Houdini 4 gives you access to “Let’s Check”*, the world’s largest database packed with high-quality analysis. Over 200 million positions annotated with deep engine calculations are saved on the Let’s Check server, with more being added every day. If you want to know what to think of a particular opening position, take a look on Let’s Check and find out in seconds what it would take your PC hours to uncover.

Example of Let’s Check in action. The brown depths on the bottom right indicate an engine
that has analyzed the position for at least an hour continuously.


Cloud Engines

The cutting-edge interface also brings the latest Cloud Engine functions, allowing you to access your engines from a remote computer, lend it out, or even rent the use of powerful third-party computers in case you need more processor power than you have.

Cloud engines can be your own or those of others. Set up private remote connections
that only you can see.

3D board

Although most users are content to use the standard 2D board, it is never quite the same thing as playing on a live chessboard. If you miss that, or would like to play games in the full 3D experience (even on Playchess), Houdini 4 has a peerless 3D board to enjoy. Bear in mind performance may and will be limited to your computer’s graphic possibilities, though the requirements are fairly mainstream by today’s standards.
