Hi Pavel,

The King (in the Chessmaster GUI) uses its own version of tablebases (called endgame database or EDGB), but doesn't probe them in the search. See this link: http://www.horizonchess.com/FAQ/Winboard/egtb.html

About Chessmaster endgame tablebase / De Koning EDGB

De Koning EDGB - Propertry format used by only Chessmaster 9000. Like the Nalimov tablebase it is a Distance to mate tablebase. Unlike the Nalimov tablebase though, it stores only wins from the white point of view (similar to Thomson)."(It) searches only for wins for White. All positions that are not proven to be won by White are stored as unknown. These unknowns might be draws, or lost by White, or (in large numbers) illegal." [From FEG or Final endgame generator for Chessmaster 9000 ]

Note the original version of the endgame generator had a minor flaw, and the EDGBs that shipped with the CDs also had this flaw. See here for more

Other differences between the De Koning and Nalimov formats are

    * Nalimov's format has KxyKz and KzKxy merged. Eg in KRBKQ the wins for white (with RB) are stored as well as the losses for white. In Thompson's and De Koning's white can only win or not win. [From FEG or Final endgame generator for Chessmaster 9000 ]

This change means that besides the usual pawn promotion case problems there are other "dependencies" problems between EGTB files (my comments)

    * Chessmaster 9000 currently does not probe the Tablebase in search but according to email correspondence this is a decision design and there is nothing in principle that stops this from occurring.

    * De Koning EDGB are slightly smaller than compressed Nalimov endgame files in general.The full De Koning EGDBs came up to about 5.7 GB , the EGDB's can function with only either the WTM or BTM files.[Note during generation, you need both files!] This can reduce the space required to as little as 2.7 GB which is extremely light on hard-disk space compared to the 7.5 GB (as quoted by most people) required for Nalimov tablebaes.

    * The Chessmaster EDGB format generation process is also faster compared to Nalimov. (Full set of 5 piece tablebase take 5 days on 1.2 GHZ Athlon) It also requires much less free RAM (less than 13MB to be precise). The generator also makes generating 6-man with KWWWWB possible on a 32 bit computer possible , but that requires about 300MB (which isn't a lot by todays standards) of free RAM

    *

      4 piece KxyK + KxKy 23 MB
      5 piece KxyzK 1.25 GB
      5 piece KxyKz 3.47 GB
      5 piece KxKyz 1.04 GB (The numbers designate the full set. For simple lookup the half set will do (either wtm or btm). The half set is somewhat smaller than half of the full set.)
    * Otherwise De Koning EDGB's are similar to Nalimov in terms of castling and 50 moves rule (see below).

GUI Fritz 11, engine The King in original directory
(C:\Chess\Chessmaster 10th Edition\) and tablebase also (C:\Chess\Chessmaster 10th Edition\Data\Database\).
Use CM10 own tablebase, or not?

I guess you will have to try to make sure I don't think The King will use the EDGB with wb2uci as they are handled by the ChessMaster GUI I believe.
