If I were feeling insufficiently geekish on any particular day, and thus found the GUI Chess App to lack an appropriate amount of tech credibility, is there a way to play chess on my Mac from the command line?
Yes! The OS X Chess app relies on the sjeng engine, which has a command line version. Type
/Applications/Chess.app/Contents/Resources/sjeng.ChessEngine and press enter to play:
Make moves with the coordinates of the origin and destination you want:
e1e4 moves the piece at e1 to e4.
Sjeng doesn't take any command line arguments, but you can edit the config file (stored in
/Applications/Chess.app/Contents/Resources/sjeng.rc). This will probably mess with your settings in the GUI Chess app; make a backup before editing.
