Just seeing this thread. Fred is correct that I'm one of the Caribbean players on the forum. We play mostly 8-ball in the VI, but there are a few of us who play nine ball. There is an even smaller group that will play 10-ball from time to time, and only three who play 14.1 at all. Unfortunately, there is no one-hole to be found in these parts.
You may also want to look up Harold Acosta, who posts here as juegabillar. He is the paset president of the Billiard Federation of Puerto Rico.
