can you hit your own ball in cutthroat
A player's turn continues so long as he legally pockets one or more object balls with each shot. A shooter can even knock in his own ball, allowing him to continue a turn in exchange for his now-weakened position. This circumstance is called ``cutting one's own throat''. If a player sinks his own last ball (intentionally or otherwise), he must sit out the rest of the game, except as noted below.
