Rh ward, and one square to either the right or the left, leaping over the intervening squares whether they are occupied or not. Thus the Knight on Q4 commands eight squares as shown on. By placing the Knight on any of the center squares the student will see that his move appears to be a leap from the square on which he stands to the next but one of a different color. From a mathematical point, the Knight's move is the diagonal of a rectangle of six squares and is as regular as that of any of the other Pieces. Owing to the character of his move he is less liable to resistance than any of the other Pieces.

The Rook moves in four directions—parallel to the sides of the board, and over any number of unoccupied squares. Thus, a rook standing on Q4 commands fourteen squares as shown in and is next in power to the Queen.
