You will have to set the tablebases path in the UCI options
This is unofficial / highly experimental / untested...so have fun !

Jean-Francois,

To avoid violating Stockfish's license, which is the GNU General Public License version 3, please include the source in the zip file with the executable or provide a separate link to the source code.

Thank you,

Well strictly speaking this is not enough. The download should contain a copy of the GPL license and a readme file with the above link (this is the "written offer").

It is much easier to include the full source in the download.

I've compiled Stockfish-rtb for 64-bit Linux, and it seems to work okay with the new tablebases.

However, I've only downloaded a few of the tablebases so far, so I'm not able to provide a full report.

[j_romang]

Yes, strictly speaking you are right, and I'm sorry that I forgot the link/GPL license.
Mea culpa, mea culpa, mea maxima culpa.
But, strictly speaking, it's the copyright holders (Stockfish's authors) that should be annoyed with this...and not you

I launched a test today (with all 5 men tables bases)

Results so far (20+0.05) :
ELO: 0.68 +- 99%: 6.82 95%: 5.18
LOS: 69.16%
Wins: 2324 Losses: 2290 Draws: 12690 Total: 17304

With the error bars..impossible to say if it's an improvement or not after more than 17000 games
I'm currently building the 6 men tablebases to retest with them.

If anyone wants a fast download you can get them individually here:

or as part of one large file.

Your download is way faster Josh !
I'm also planning to share the 6 pieces tablebases (80Go), so maybe a torrent will be more usefull for that.

You are right Gabor ; 7 years since the last update of my chess engine
