When neither party can give checkmate, the game is drawn

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.

The Queen is by much the most powerful of the forces.

When a Piece or Pawn is in a situation to be taken by the enemy, it is said to be en prise. To put a piece en prise, is to play it so that it may be captured.

The Bishop moves diagonally forwards or backwards, to the extent of the Board.

The Bishop and Knight, in contradistinction to the Queen and Rook, are called Minor Pieces.

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.
