Caribbean Stud Poker Strategy

Caribbean Stud Poker strategy advisor

Tap your five cards, then tap the dealer's single up card, and the advisor returns the optimal play. It follows the published near-optimal Caribbean Stud Poker strategy exactly, so you can drill raise-or-fold decisions until they feel automatic:

How Caribbean Stud Poker is played

Caribbean Stud Poker is a five-card casino game played against the house, not against other players. You start with an ante bet. Then the cards are dealt: you get five cards face down, and the dealer gets five cards with one dealer's card face up. After looking at your five cards and the single dealer's up card, you make your only decision of the hand — fold and lose the ante, or raise by placing a bet of exactly twice the ante.

The catch that shapes all Caribbean Stud Poker strategy is the qualification rule: the dealer must hold at least Ace-King high for the dealer's hand to qualify. If the dealer does not qualify, your ante is paid even money and your raise bet simply pushes. If the dealer qualifies and your five-card poker hand beats the dealer, both the ante and the raise bet win, with the raise paid on a poker pay table. If the dealer qualifies and beats you, you lose both bets. Because a fold costs only the ante while a raise risks three units, correct strategy is about raising exactly when your hand is a favourite to be worth that extra risk.

The simple near-optimal strategy

The full computer-optimal Caribbean Stud Poker strategy involves dozens of edge cases, but almost all of its value is captured by a three-line rule that is easy to remember at the table. This simple strategy gives up only about 0.02% versus the exact optimal strategy — a difference too small to matter in real play.

• Raise with any pair or better. A pair, two pair, trips, a straight, a flush — any made poker hand — is always a raise, regardless of the dealer's card.
• Fold with less than Ace-King high. If your best five cards do not even reach Ace-King high, fold and surrender only the ante bet.
• With exactly Ace-King high, use the dealer's up card. Raise if the dealer's up card is a 2 through Queen and matches the rank of one of your cards, or if the dealer's up card is an Ace or King and you also hold a Queen or Jack. Otherwise fold.

That Ace-King rule is the only part that depends on the dealer's card, and it is exactly what the advisor above evaluates for you: when your hand is Ace-King high, whether the dealer's card matches one of yours — or whether a card matches at all — flips the decision between raise and fold.

Why the Ace-King rule works

Ace-King high is the borderline hand in Caribbean Stud Poker: sometimes a favourite to be worth raising, sometimes not. The dealer's up card is the tiebreaker. When one of your five cards matches the dealer's up card, the dealer is less likely to pair that rank, which tilts the hand your way. When the dealer shows a high card like an Ace or King, holding a Queen or Jack means your Ace-King high is stronger relative to the hands the dealer can make. Outside those cases, an Ace-King high hand is a slight underdog, so the strategy folds it. You will fold most Ace-King high hands — that is correct, and it is where a lot of players leak money by raising too often.

Caribbean Stud Poker pay table

When the dealer qualifies and you win, the ante pays even money and the raise bet is paid on this schedule (typical table):

Remember that this pay table only comes into play when the dealer qualifies. A large share of hands end with the dealer failing to qualify, in which case a premium hand wins only the even-money ante — a quirk of the game that no amount of strategy can fix.

The house edge

With the optimal Caribbean Stud Poker strategy, the house edge is about 5.22% of the ante bet. Measured against the total amount you actually put at risk once the raise bet is included — the element of risk — the figure is closer to 2.56%. Either way, Caribbean Stud Poker carries a higher edge than games like Three Card Poker or blackjack, so it is best treated as an entertaining casino game rather than a low-edge one. Playing the correct strategy keeps you at that 5.22% and no worse; playing hunches pushes it higher.

The progressive jackpot side bet

Most tables offer a progressive jackpot side bet, usually a $1 wager that pays on premium hands regardless of what the dealer does. A flush or better wins a fixed amount, and a royal flush typically takes the whole progressive jackpot. It is a fun bet, but the math is unkind: the progressive jackpot side bet normally carries a house edge many times higher than the main game, because the jackpot rarely grows large enough to make the bet fair. As a rule of thumb, skip the side bet unless the posted progressive jackpot has climbed to an unusually high figure — only then does the jackpot begin to offset the edge. The core Caribbean Stud Poker strategy above concerns the ante and raise bets only; the side bet is a separate, optional gamble.

Common mistakes

The biggest strategy leak is folding made hands out of caution — every pair, even a pair of twos, is a raise. The second is the opposite error: raising weak Ace-King high or ace-high junk because it "looks like something." And the third is chasing the progressive jackpot on every hand. Fix those three and your Caribbean Stud Poker strategy matches the near-optimal play almost perfectly.

Practise the decision

Deal yourself a few dozen hands in the advisor above, guess raise or fold, then check the engine-verified answer. Once the pair-or-better raise, the sub-Ace-King fold, and the Ace-King dealer's-up-card rule are automatic, you will play Caribbean Stud Poker at its lowest possible edge.
