UCI chess engine written from scratch in Golang. Started as a competitor to my previous engine done in Java - Machess. But generally it's just an excuse to learn some Go.
Currently, it plays with modest strength and I expect it to be around 1350-1450 ELO on CCRL blitz list.
Feel free to try it out! Please report any obvious bugs or crashes you may find. :)
