Movement Of The Pieces And Practice. The King can move in any direction, but only to a square adjacent to the one he occupies. He can also capture any adverse man that comes near him, unprotected by any other piece or Pawn ; but he cannot place himself on any square which is attacked by an adverse man, for the King is the only piece that is never taken ; he is the soul of the game, and a player may have all his men, and being checked (the meaning of
King which will be explained hereafter), without being able to remove the attacking or checking man, he is checkmated - that is to say, the game is lost. Though the King can only move one square at a time, there is one exception to this rule, which is only permitted once in a game, that is, the act of castling. For this a player has two choices; he may castle to the right or to the left. This is done by moving the King two squares in either direction towards the Rook with which he castles, and placing the Rook on the other side of the King on the square next to him. For instance, supposing white to have his two Rooks in each corner, and the King on his original square, the King can castle on the left, which is called his Queen's side; or on the right, termed the King's side. In the former case he would be placed on the square originally occupied by a Bishop, and his Queen's Rook would have to stand on his Queen's square; in the latter he would be moved to a square where his Knight stood, and his Rook would occupy the square of his Bishop. There are, however, certain conditions attached to the privilege of castling. 1. You cannot castle after having moved your King, or the Rook, with which you wish to castle. 2. There must be no piece between the King and the Rook, whether your own or your adversary's. 3. You cannot castle while in check, nor to a square where the King would be in check ; nor can the King castle, if, in doing bo, he passes a square which is attacked by an adverse piece or Pawn. The two Kings cannot, of course, come close to each other, but must have at least one square between them.
The Queen is by far the most powerful of all pieces, combining the action of the Rook and the Bishop. It moves in a straight line, rank or tile, backwards and forwards, and also diago-nally, but only over empty squares, like ail other pieces, except one. Place a Queen on the empty board, on the fourth square, counting from the King's square upwards, and thus placed in the centre of the board, she will be found to bear upon twenty-seven squares, exclusive of the one she occupies. Placed in one of the four corners, where her action is most limited, she will still command twenty-one squares besides the one she stands on.
The Rook, also called the Castle, is next in importance to the Queen. She moves in a straight line, backwards or forwards, or sideways, always over empty squares. It is a peculiarity of this piece, that, whether it is placed in the middle of the board, or in a corner, it always commands the same number of squares, fourteen, besides the one it stands on.
