Facebook Messenger Chess Have anyone here experimented the Chess of Facebook Messenger?
I've heard about this and would like to get the comands/ codes to play.
GM Smerdon has written a blogpost about this.

Some of the commands:

Case sensitive algebraic notation:

@fbchess Bg7
@fbchess e4

@fbchess undo
