I posted gnuchess 5.07.173b at the usual place
http://alpha.uhasselt.be/Research/Algeb ... s-release/
There are linux, windows and android binaries.
Note that this is a further development of the old gnuchess 5 branch. This is different from the
gnuchess 6 branch which is a rebranded fruit.
The latest released version of my gnuchess 5 branch was 5.07.170.5b.
This version adds FRC support as well as some ELO.
Note that Arena uses an outdated protocol for FRC under UCI. I made no effort to support this.
On Arena you can use gnuchess in xboard mode if you want to play FRC games.
To compile gnuchess with Gaviota Table Bases support you need libgtb which comes with the GTB distribution.
