GNU Backgammon wins the 2006 Computer Olympics !!
I'm back from Torino where GnuBG has just won the 2006 Computer Olympics Backgammon "tournament", defeating its only opponent, BGBlitz by Frank Berger. Final score is 3-1 (best of 5 matches, 15pts each), with individual scores of 3-15, 16-12, 15-8 and 17-13.
Analysed matches (supremo, g11 met) can be downloaded here
For the records, BGBlitz is truly strong: it has been rated by gnubg analysis in the 4 matches as 1997.4, 2004.5 2035.1 and 2025.4 (FIBS rating) and in the first two matches, Frank used by mistake the "old" engine (winning one of them anyway).

One-sided race database reaches the midpoint
A one-sided race database that extends to the 13-point is now available for download. The file is a large one 1.6 GB, and may take close to a day to download even on broadband.
Other bearoff and hypergammon databases can be downloaded from here.
General information about using bearoff databases can be found here, including instructions for rolling your own.
The last GTK+-1.3 Windows build available
Some of you have reported that there was a bug in the previous version. Cube analysis was inconsistent and gave different results each time you pressed a evaluation button. This bug has been found and fixed.
Because of this bug fix, here is the last build of GNU Backgammon for Windows based on GTK+-1.3 libraries that will ever be available from this site.
The installation archive is avaliable for download here
. You can check agains my detached signature here
. If you want the md5 checksum it should be: ff6105618d914db4bfc8e717ca820468.
The archive contains the usual stuff with the main executable of the CVS sources from Wednesday March 2nd 2005.
