One minor point. I don't know whether somewhere you've acknowledged the people who helped you test Komodo (of whom I was the least).
We do plan to put up an acknowledgement page because we have depended on a lot of people to help us. This includes Jim Ablett and Dann Corbitt who helped me compile and debug things (Dann has spend many hours debugging my code) as well as Aart Bik who also did some debugging and found a bug in Komodo. A number of people have helped me test - and my fear is that I would leave someone out and I did not carefully track each one. What immediately comes to mind is a guy name Djordje, Throsten Czub, Clemens Keck, Marek Soszyski and all involved in various rating agencies.

There are also people who have influenced the development of Komodo (as well as probably every other program in existence) and a partial (very incomplete) list goes like this: Claude Shannon, David Slate, Bob Hyatt, Tony Marsland, Frans Morsch, John Stanback, Tony Scherzer, Chrilly Doninger, Vincent Diepeveen, Fabien Letouzey, Richard Vida, Ken Thompson, Larry Atkin, Don Beal, Hans Berliner, Mark Leffler, David Kittinger, Dan Spraklen, Kathy Spraklen, Jonathon Shaeffer, Aske Platt, Feng-hsiung Hsu, Murray Campbell, Albert Zobrist ....

I could go on and on and this is only a fraction of the people and it's impossible to document who they all are and what they did. Some of them influenced me personally perhaps more than the contributed to computer chess but they all made contributions to computer chess.

When the dust settles on this version I am immediately going to work on the MP version. So the next version will have a single processor version and an MP version that you can purchase.

Thank you !

Buy the way, will the next version MP only include the "MP" advantage or by then there will also be some other improvements over version 3 ?

For what it's worth, on my WinTel64 box it runs fine, as it does on my Android phone. Regarding Komodo's weakness in tactics, I ran it on Frank's position, and compared with other engines, also limited to a single thread, to keep them all on the same footing:

All engines are using ONE core and 2 GB hash. The move to find is Bxh7+

Absolutely. I regret having announced Komodo before having this all ready - next release won't be like this.

Hi Don!

First of all, thank you very much for all the Komodo team, testers et al for providing such a great engine and even free.

Here is my question: have you planned a release date of a stable compile of Komodo 3 for Windows (all processors and 32&64 bits)? A last thing: are you going to support some kind of EGTB or bitbases in the next release (maybe Komodo 4?)? Thanks in advance.

Regards from Spain.

The planned release time was early this week and it didn't happen. We intend to support all Linux, Windows and Mac x86 platforms. So just wait and we will have these versions for you.

In the future we will support databases. Probably Gaviota but I have not thoroughly looked into this yet. No date promises for this yet.
