In all these decades, I never heard anything about GNU Chess. Does it have any kind of style, or is it basically typical 1980s computer play?
If you look at the source code you can see the template for all modern chess engines.
Plays strong for it's time period. I guess it's around TSCP strength.

The strongest is GNU Chess 5.60 x64 (also known as GNU Cheese 1.00 x64) - its internals contains private engine parts (Cobalt by Chua Kong Sian - Singapore) like parts of a commercial engine (Gazebo by Stuart Cracraft - USA). GNU Chess versions were and are legends in computer chess.
GNUChess was one of the first open-source engines. I found the source code somewhat opaque: it is not well documented and has some quirky features. But at least it was out there, at a time when most engines were commercial and closed-source.
GnuChess 4.x I think are the last releases built on the original code base. John Stanback was the developer on versions 2-4. GnuChess 5 is a different engine. Version 6 is based on Fruit.
By modern standards it is quite weak but it was quite a decent engine for its time.
