Chess program for Linux/Unix console For reasons I'd rather not get into, what chess programs work well on the console (ie. does not require X Windows)? Something with an ASCII visualization of the board would be incredibly helpful (I'm still a chess newbie).
After installing GNU Chess run the command gnuchess from the terminal, it would look something like this:

~$ gnuchess
