Houdini 6 and 6 Pro

With Houdini 6, you not only gain in terms of computing power, but also in terms of time! The new engine delivers better performance even if you only let it calculate for half as long as the previous version!

Houdini 6 has been put to the test in various areas and thoroughly refined in all the right places: position evaluation, search, time management and use of the endgame tablebases have been improved, as has parallel processing.

Houdini 6 delivers particularly exceptional results on systems with a large number of CPUs, and can run up to 128 threads on high-end hardware.

Despite all the detailed technical improvements, Houdini has kept its creative and imaginative style of play, and where other programs see no future or are locked into a draw, Houdini delivers surprise after surprise with hidden resources. You can certainly look forward to using this latest version of the true wizard among the chess programs!

The most powerful position solver ever

The enhanced "Tactical mode" transforms Houdini 6 into the most ingenious position solver of all time and improves again on the records held by previous versions in tactical benchmark tests. In addition, "Tactical mode" can now also be assigned an exact number of threads, giving you additional flexibility.

Included with your purchase:
  • Houdini 6 PRO engine: The engine can support up to 128 processor cores and 128 GB of hash memory
  • Fritz 15 user interface
  • Premium membership for playchess.com and your ChessBase Account (6 months)

Houdini 6 is much faster than previous versions & now rivals Komodo 11 for best analysis engine.

Chess Gator: I suggest you try Komodo 9, which is also free. Never been a Stockfish fan, as some of its evaluations are b.s.

I can download Stockfish for free and it is stronger than Houdini 6, so why am I going to pay a ridiculous amount of money for H6?

Absolutely Retarded!

Darius - A difference of 30 ELO points....c'mon is that even worth mentioning? I'm a sub-2000 player and I have no qualms or fears about an opponent of mine who is +/- 30 points from me when I play in a tournament. Let alone at an ELO rating of 3300 a difference of +/- 30 points is even less significant!

Both engines would be comparable without doubt.

To most players it makes little if any difference which is stronger. A few months later it will probably change again. To me what is clear is they are all stronger than the strongest human and for analysis purposes that is enough for me. Any increase now is a minor matter and I don't need/wish to show I've got the latest. :)

I'm not a CCRl expert, but I believe the top three engines at the CCRL computerchess.org site, SugaR XPrO 1.2, Komodo and Houdini, are overrated. I think they optimized these engines to play vs each other to inflate the ratings. If you ever play engines on Arena like I have, you notice certain engines have bugs that can be exploited, and further, once an engine is about 100 points stronger than another engine, it will not win 66% of the time as Elo statistics show but 90% of the time. That's a clear case of an engine winning because the other engine keeps making the same mistake in the evaluation function for certain positions that seem to crop up all the time. I personally think the top Elo of engines is about 3200 to 3300 Elo, when on a human scale, which means Magnus playing at 2900 Elo would win about 10-20% of the time vs the top engines. If draws were counted as wins for Magnus, he might even win in a human-machine match?

Hello all! Do we know if Fritz 16 will be released shortly after this one? And will any update/new features make their way back to Houdini 6? Trying to decide if to wait until 11/28 for Fritz 16

Jarman, Houdini6 is stronger around +30 ELO than Komodo11.
dariusz.domagala.pl@gmail.com dariusz.domagala.pl@gmail.com 10/18/2017 01:20
Lachesis,now the strongest engine in the world is Stockfish, AsmFish: +30-60 ELO according to pc computer power :-)
vanhelsing vanhelsing 10/18/2017 12:50
This looks promising.
Lachesis Lachesis 10/18/2017 12:33
I also was of the belief that Komodo 11 was the strongest current chess engine?
Jarman Jarman 10/18/2017 12:21
I was under the impression that Komodo 11 was leading the pack. What is the ELO rating of this version of Houdini?
