Hello.What free software programs exist for playing the game of Go (engines, SGF editors, and Go server clients) that are actively maintained or at least usable?.
As for engines, I know of Pachi and Michi.As for clients, I know of qGo. Another client, CGoban 1 has been long unmaintained; the last version is from 2002.
There is also goGui which has been unmaintained since 2013. Regards.
