Jumping: You capture an opponent's piece (piece or king) by jumping over it, diagonally, to the adjacent vacant square beyond it. The three squares must be lined up (diagonally adjacent) as in the diagram at the left: your jumping piece (piece or king), opponent's piece (piece or king), empty square. A king can jump diagonally, forward or backward. A piece which is not a king, can only jump diagonally forward. You can make a multiple jump, with one piece only, by jumping to empty square to empty square. You can only jump one piece, with any given jump, but you can jump several pieces, with a move of several jumps. You remove the jumped pieces from the board. You cannot jump your own piece. You cannot jump the same piece twice, in the same move. If you can jump, you must. And, a multiple jump must be completed; you cannot stop part way through a multiple jump. If you have a choice of jumps, you can choose among them, regardless of whether some of them are multiple, or not. A piece, whether it is a king or not, can jump a king.
