Building gnubg on MS Windows
Here's some instructions that allow you to build the latest version of gnubg on MS Windows. It is mainly aimed at people wanting to develop or test gnubg.
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).

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.
