Houdini 6 Standard
Best buy for most users with main-stream hardware. Supports up to 8 threads and 4 GB of hash.
Houdini 6 continues the impressive surge made by its predecessor by adding another 50 to 60 Elo in strength, to become once again the strongest engine that money can buy. This playing strength increase means that Houdini 6 is stronger than Houdini 5 using twice the time; or in other words, upgrading to Houdini 6 is like doubling the computational power of your computer for chess.
Every aspect of the engine has been thoroughly reviewed and refined: evaluation, search, time management and table base usage. Houdini 6 makes better use of multiple threads and will be particularly strong on hardware with many cores. To take into account the recent availability of mainstream processors with 8 cores, Houdini 6 Standard version now supports up to 8 threads. On high-end hardware Houdini 6 Pro can make use of up to 128 threads.
The evaluations have again been calibrated to correlate directly with the win expectancy in the position. A +1.00 pawn advantage gives a 75% chance of winning the game against an equal opponent at blitz time control. At +1.50 the engine will win 90% of the time, and at +2.50 about 99% of the time. To win nearly 50% of the time, you need and advantage of about +0.60 pawn.
The enhanced Tactical Mode turns Houdini 6 into the most impressive position solver ever, improving on the records the previous Houdini versions set for solving tactical test suites. When running multiple threads the tactical mode can now be activated for only some of the threads.
