I''d like to add support for Endgame Tablebases to my chess engine, but can''t seem to find any information on the file formats. I''ve got a stack of .TBS and TBD(?) files, but just don''t know what to do with these. Anyone use these before? Will

I think most people in the free world know how to use a search engine.

As mentioned in the first post, I want to add support to my own chess engine, not import these files in to somebody elses.

There seem to be three major formats for these files. I''m looking for a file format spec for any or all of them. What I don''t need is a general description of what they do.

Thanks,
Will

Use Nalimov tablesbases. That''s the most popular currently. You can download them at ftp.cis.uab.edu/pub/hyatt. I think you then go to the TB directory, and then there are directories named three, four, five, and six, each containing endgames for three, four, five, and six pieces. It comes with probing code. You can find that in either tbexe.zip or tbgen.zip.

Eugene Nalimov said he has finished about 250 GB of the 6 man endings so far, and they are uploading them to Robert Hyatt''s server as we speak (or they''re waiting for a new machine or something). They will probably take over 1 TB of space when they''re finished.

Only those in the free world? (grin)

Seriously, many questions I see on forums can be answered very quickly with a search on
Google....

Isn''t it safe to assume that people have already searched Google? I think that if you (the respondant) can find an answer in 2 seconds via Google, the poster probably already did, but just wasn''t happy with what they found.

In this case, I had already visited the link that Fruny posted before coming to GameDev. I wasn''t satisfied with the information I found, so I came here and posted. Kind of like looking for a second opinion.

The available documentation (the postscipt files) are too ''chessy'' for me; I''ve spent too many hours working on chess over the past few months and don''t have the energy to plow through them. I was looking for something a little more compact and to the point.

I don''t think so, based on some of the questions I see posted here.

If someone searches google, and asks a question like "I''ve searched all over google and can''t find ........, can you help?", then I would assume they have searched google.
