When neither party can give checkmate, the game is drawn.

A player is said to have the opposition when he can place his King directly in front of the adverse King, with only one square between them. This is often an important advantage in ending games.

A Rook is of the value of five Pawns and a fraction, and may be exchanged for a minor Piece and two Pawns. Two Rooks may be exchanged for three minor Pieces.

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.

Each player, it will be observed, has eight superior Pieces or officers, and eight minor ones which are called Pawns; and, for the purpose of distinction, the Pieces and Pawns of one party are of a different color from those of the other.

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.
