Wondering if anyone has heard of a game in which the object is to score 3 points (or sometimes 5 for a longer game) in each of five categories of shots: ball to ball, one rail, two rails, three rails, and rail first. Any rail first shot counts only in that category whether or not the cue ball goes on to contact one or more rails before hitting he second object ball. I learned it from a guy who grew up playing it in central Kansas. He said they called it both Train and Chinese Billiards.
