A piece (either Knight or Man) may leap in any direction (horizontally, vertically, or diagonally) over a friendly piece (either Knight or Man) that occupies an adjoining square, provided that there is an unoccupied square immediately beyond it in a direct line onto which the leap may be made. This move is called a Canter. Pieces cantered over are not removed from the board. A player may canter over more than one piece during the same move, but may not make a Canter that ends on the same square from which it began. When cantering over more than one piece in a move, the direction of the move may be varied after each Canter. A player is never compelled to canter, nor when cantering is he compelled to canter as far as possible.
