Houdini 4 PRO
The world's strongest chess engine running on the ChessBase Interface
The new version, Houdini 4, goes even further, providing the chess world with yet another increase in playing strength: at least 50 Elo points, thanks to a host of improvements in its search algorithms. They manifest themselves in different ways, in various phases of the game. In the opening Houdini 3 demonstrates an even more subtle understanding of space and activity; in the middlegame the program spots quicker than before when pieces are in danger of being dominated; and in the endgame the right evaluations and solutions to problems are found much sooner thanks to a faster, deeper search.
During the course of this new development and the fine tuning of the engine Houdini played, believe it or not, ten million test games!
Houdini 4 is supplied with the latest Deep Fritz 14 chess interface and thus puts at your disposal all the training and analysis functions of the world's premium chess program. Included in the package are a one-year classic membership to the chess server Playchess.com, online access to the world's largest analysis database åÒLet's CheckåÓ* and the use of the ChessBase Engine Cloud.

- The Houdini 4 engine

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 (Endgame Turbo 3) 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.
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.

Still one of the best chess programs
Posted by Paul Ruffle on Feb 20th 2017
I had stopped collecting Chessbase products for a number of years and Houdini 4 was one of those gaps in my collection.
In it's day this was probably the best chess program in the world. Even though it has now been supplanted by Houdini 5 this is still an excellent piece of kit.
It has a reputation for finding tricks and resources in positions that can't be cracked by other engines. I've got a white to mate in 3 problem where the first move is to promote a bishop. Houdini 4 can find the correct answer, whereas Fritz 15 and Komodo 10 can't!
It's ability to read the new Syzygy endgame tablebases, which unfortunately are separate from this program, is a major plus. With these it's endgame knowledge is perfect. Houdini is one of those engines that shows "TB" when it is accessing the endgame tablebases, often quite early in the game. With other engines you can't always be sure if they are referring to them or not.
This comes with a Fritz 14 interface but my intention was always to run it in the Fritz 15 interface once I had installed it.
You won't be able be able to buy this soon so get it whilst stocks last.
