The Pawn moves only one square at a time, and that straight forward, except in the act of capturing, when it takes one step diagonally to the right or left file on to the square occupied by the man taken, and continues on that file until it captures another man.
Be cautious of playing your Queen in front of your King and in subjecting yourself to a discovered check. It is better when check is given to your King to interpose a man that attacks the checking Piece than with one that does not.
For playing a man to a square to which it cannot be legally moved, the adversary, at his option, may require him to move the man legally, or to move the King.
For touching an adversary's man, when it cannot be captured, the offender must move his King.
When the King is checked, or any valuable Piece in danger from the attack of an enemy, you are said to interpose a man when you play it between the attacked and attacking Piece.
