As you can see in the picture I did a king side castling (playing white). To do that I typed 0-0. It appears as if gnuchess understood 0-0 and did in fact show castling I just did. However just after that it returned an "unknown command" error despite already thinking about its next move. Then it just froze.
I launched gnuchess with -g and -e. Maybe that's the reason for this weird behavior? Anyway it's a game breaking glitch.
Yours sincerly, Tom.
