I don't have much experience with Caribbean Stud, so I looked it up. After all, I'm not the only internet poker guide on the block.
To play, every player places his ante on the layout where indicated; all ante wagers must be placed prior to the dealer announcing "No more bets". Each player and the dealer will then receive five cards, face down. The dealer will turn over one of his cards, then push the cards toward the players, after which the players may look at their cards. They may only look at their own cards, and may not discuss what they have with any other player at the table.
Players have the option to play or fold; if they choose to play, they place their bets (twice the amount of their respective ante) in the bet box. If they choose to fold, they forfeit their ante. After all the players have made their decisions, the dealer reveals his hole cards. The dealer only plays with an ace/king or higher; he then compares his cards to the players' cards (individually, right to left), and the players' hands that beat the dealer's qualifing hand wins.
