Subject: Chessbase - 6 Man Tablebases
|
Have come across a problem trying to use 6 man tablebases with
Chessbase/Fritz.
Trying to test the following position:
1k6/p4K1R/r7/8/7P/8/8/8 w - - 0 57
Using SysInternals FileMon and Process Explorer, I have identifed that
Chessbase crashes when it loads the six-man tablebase in the format
that CB is expecting.
This file is available as 7 parts, namely:
krpkrp.0.nbw.emd
krpkrp.1.nbw.emd
krpkrp.2.nbw.emd
krpkrp.3.nbw.emd
krpkrp.4.nbw.emd
krpkrp.5.nbw.emd
krpkrp.6.nbw.emd
However, CB keeps crashing as soon as it has loaded krpkrp.1.nbw.emd -
is there anyone out in the ether using CB or Fritz and a Six-Man
tablebase (hopefully krpkrp).
I have tried concatentaing the files into one, called krpkrp.0.nbw.emd,
and found by FileMon that Chessbase would open the file.
Details from FileMon below, this is with the concatenated file being
called krpkrp.0.nbw.emd - unfortunately I can't get CB to use the
tablebase for the set position.

Any ideas?

Doh!
Sorted now - went back to the TB site and checked out the MD5 of the
files, it would seem two of the files were corrupt. D/L the files
again, and the tablebase is being loaded and is OK now.
It would seem that CB/Fritz crashing is typical of a corrupt EMD file.
Why the hell they could not put code in to indicate the file was
corrupt - ala Wilhelm (a free chess program that uses EGTB) - only
Chessbase can tell I guess.
Thanks for the SYSINTERNALS, their software utilities are amazing!
