History
The first version of GNU Chess was written by Stuart Cracraft. This project is one of the older parts of the GNU package of software, having started in 1984, the author having collaborated with Richard Stallman, pre-GNU.
Versions from 2 to 4 were written by John Stanback. Version 5 was written by Chua Kong-Sian. Version 6 was written by Fabien Letouzey. Dozens of programmers have enhanced and expanded GNU Chess.
In 2011, GNU Chess underwent transition to version 6, which is based on Letouzey's Fruit 2.1 chess engine.
Some GNU Chess enthusiasts still maintain the 5.07 code base, adding new features and making it stronger. According to CCRL the current version of GNU Chess 5 is about 350 Elo stronger than the original FSF version. It is still weaker than GNU Chess 6 however.

“What you don’t understand is that it is possible to be an atheist, it is possible not to know if God exists or why He should, and yet to believe that man does not live in a state of nature but in history, and that history as we know it now began with Christ, it was founded by Him on the Gospels.”
—Boris Pasternak (1890–1960)
“Only the history of free peoples is worth our attention; the history of men under a despotism is merely a collection of anecdotes.”
