By virtue of its economic uniqueness , this island seems to have appeal for an interesting type of person: the young, unattached entrepreneur with some successes behind him and a desire to do more from an environment that doesn't hinder him. Immediately upon arrival, I bumped into A , a neighbor who's also waiting for his unit to be built and has an interesting story behind him. At 24, and originally from Tampa, Florida, he is a professional poker player who apparently earned significant sums playing poker on the net. Forget Chris Moneymaker : A makes his lunch out of players like him. I saw A talk to me fluidly while playing 4 poker games simultaneously, on tables where pots climb to US$1,000 and beyond. He says he has downsized his gaming - he used to play tables with still bigger bets, even 15 at a time; he would be $50,000 up or down at the end of a day. He's been at it for some 5 years; it took him the first 2 years to start earning serious money. Three months ago,
