PKM said:3-cushion looks really difficult. How do you even begin to learn the game? In pocket billiards, you can pick it up right away and at least try to make shots, if not worrying about position. In 3C, I would hardly know where to begin to see those patterns. Do most players come from other games first?
My only experiance playing carom games are a few games of English Billiards and playing some billiards on a 9 foot pool table.
However I doubt you would start with 3 cushion. I would think you should start by playing straight rail billiards and then 1 cushion, 2 cushion and then 3 cushion billiards.
