The fifth incarnation of an interesting and strong chess engine written in the Go language. About 3100 Elo.
Counter by Vadim Chizhov is free, open source and published under the GPL3 license.
The latest version is a breakthrough of sorts, as the author has implemented NNUE eval instead of the earlier hand crafted eval.
Hopefully, this will be a "springboard" for further fruitful development of this chess engine.
According to Darius's tests, the latest fifth version does not bring an increase in strength compared to the fourth version. Details will be published in the next issue of MCERL.
