I was looking thru one of the Byrne books and he has a section called something like, "Shots that made my jaw drop". And one of the shots is a jump shot over the first ball. Now, it's a rare shot even in pool outside 9 ball, but I've never seen anyone shoot a jump in 3C, pro or otherwise. It's up there with using the bridge - always seems like laying across the table or shooting lefty is preferable. If all else fails, maybe a rail first or a masse. I was just curious - have you ever seen a serious player do a jump shot, and/or can you think of a position where there is really no other choice?
