iii. The players draw lots for the first move, and take the move

alternately.

[When odds are given, the player giving them moves first. White generally moves first; therefore, if black win the move, the board is turned. It is usual to play with the white and black men alternately.]

iv. The piece touched must be moved. When the fingers of the player have once left the man, it cannot be again removed from the square it occupies.

[Except the move be illegal, when the opponent can insist on the piece being moved in the proper manner, or for the opposing King to be moved.]
