♜ The Rook can be moved any number of squares at a time, forward or backward, but only in vertical or horizontal lines, never diagonally. The Rook’s movement is of course limited by pieces obstructing its path, for it cannot jump over anything. At the beginning of the game, for instance, the Rook cannot move at all.
♝ The Bishop can be moved any number of squares at a time, forward or backward, but only in diagonal lines, never horizontally or vertically. For this reason the Bishop never leaves the squares of the same colour as that on which it originally stood. A Bishop is often spoken of as a white Bishop or a black Bishop, which does not mean that it is one of White’s Bishops, or one of Black’s; but that it stands upon a white or black square. Like the Rook, the Bishop cannot jump over other pieces, and cannot be moved at all until one or other of the two Pawns diagonally in front of it have opened the way.
♛ The Queen combines the movements of the Rook and Bishop, and can be moved horizontally, vertically, or diagonally, any number of squares at a time, provided that the path is clear. Like the Rook and Bishop, she cannot move at all until some of the adjoining pieces have made a way for her.
♚ The King has the same movement as the Queen, but is limited to one square at a time. The King is not allowed to move to a square which would expose him to capture by adverse pieces, for reasons which will presently be explained.
♞ The Knight has a very peculiar movement, which is L shaped, and necessitates his changing the colour of the square he stands on, every time he moves. The simplest way for the beginner to learn the Knight’s move is to observe that he must go two squares, neither more nor less, in a vertical or a horizontal direction, and must then change the colour of the square he stands on by going one square either to the right or left, which will complete the L shaped movement. Diagram No. 4 will show that when the Knight is away from the side of the board, he may go to any one of eight different squares; but when he is in a corner he can go to two only. For that reason Knights are much more powerful when placed near the centre of the board.
No. 4.
The peculiarity of the Knight’s move is that it is not retarded by other pieces, because the Knight can jump over them, a privilege which is not given to any other piece on the board. In Diagram No. 5, for instance, the Knights have been legitimately moved, but no other piece could be moved until the Pawns had made way for it.
