The 58th engine in my collection written in Go is the Romanian-made ArGO. It is very powerful, with an evaluation based on NNUE. It is the third engine from Romania written in Go (following Zurichess and Alpaca). Author: Andrei Teculescu. I am currently compiling the 59th engine written in Go. It is a rarity-it supports both WB and UCI protocols (to my knowledge, only Alpaca also recognizes both). It was written by a woman. As for the 60th functional engine in Go-it simply does not exist at this moment!

The oldest chess engine written in Go that I know of! It supports both the UCI and Winboard (XB) protocols. It comes from the Bengal region-specifically, Calcutta, India. It is number 59 in my collection. Another functional chess engine written in Go-I doubt any others like it still exist today!

A beautiful attacking game:
