Simply open up a conversation with a friend and type
@fbchess play to start a game.
It appears a board like shown in the picture with black and white pieces. The color for the players are randomly assigned but if you want to play with a specified color (black or white) then write:
@fbchess play white: you play with white pieces.
@fbchess play black: you play with black pieces.
STEP 1: HOW TO MOVE THE PIECE
Select a piece using the following:
P for pawn
K for king
Q for queen
B for bishop
N for knight
R for rook
For moving pieces facebook messenger uses the typical chess notation: that is first write the letter and then the number where to move the desired piece, prefacing every instruction with the command @fbchess
So, for moving the pawn to the position d4, write:
@fbchess Pd4 and press Enter
If more than one piece can go there, you’ll be asked which one to move.
Move the Knight to the position h3:
Move the rook to the position a6:
Move the bishop to the position g2:
Note: the letter that denotes the piece must be written in capital letter.
If you type a movement so that none of the piece can be moved to that place, you got the following message:
None of your pieces can make that move.
