The author, Mr. Rak Laptudirm is successfully developing his chess engine, which is beginning to compete with such well-known ones as, for example, CT800, Phalanx or even Deep Junior 2010.
Mess is a free open source chess engine under the Apache Version 2.0 license. A kind of curiosity, is that it is written in Go language.
I mentioned the topic of Mess on the occasion of the last issue of MCERL; I will certainly be watching and rooting for the further development of this chess engine with great potential.
Thank you very much to the author for providing the Mess chess engine for so many platforms.
