Caribbean Stud Poker Calculator: Master the Raise/Fold Decision
Caribbean Stud Poker pits your five-card hand against the dealer's. Our calculator shows optimal raise/fold decisions for any hand, helping you minimize the 5.22% house edge and understand progressive jackpot math.
What Is Caribbean Stud Poker?
Caribbean Stud is a table poker game where you compete against the dealer, not other players. After seeing one dealer card, you decide to raise or fold.
Quick Answer: The key Caribbean Stud decision is raise (2x ante) or fold. Optimal strategy: Always raise with pair or better. With A-K, raise if you match the dealer's upcard, or if you have Q-J in your hand. Fold all other hands. House edge is 5.22%—one of the highest table games.

Caribbean Stud Rules
Game Flow
- Ante: Place mandatory ante bet
- Optional: Place progressive jackpot bet ($1)
- Deal: Receive 5 cards face down; dealer gets 5 (1 face up)
- Decision: Raise (2x ante) or fold (lose ante)
- Showdown: Dealer reveals hand
Dealer Qualification
The dealer must have A-K or better to "qualify":
| Dealer Hand | Result |
|---|---|
| Qualifies, you win | Ante pays 1:1, raise pays per table |
| Qualifies, dealer wins | Lose both ante and raise |
| Doesn't qualify, you win | Ante pays 1:1, raise pushes |
| Doesn't qualify, dealer wins | N/A (you already won) |
Dealer doesn't qualify ~44% of the time.
Optimal Caribbean Stud Strategy
Always Raise With
- Any pair or better
- A-K-Q-x-x or better (any)
- A-K-J-8-x or better (any)
Always Fold With
- Less than A-K high
- A-Q-x-x-x or worse (no pair)
A-K Hands (The Tricky Part)
With exactly A-K high:
| Condition | Action |
|---|---|
| Dealer upcard matches one of your cards | Raise |
| You have Q-J in hand | Raise |
| Dealer upcard is 2-Q, you have Q in hand | Raise |
| Dealer upcard is A or K | Raise (you block their pair) |
| None of above | Fold |
Simplified A-K Strategy
If memorizing is difficult:
- Raise A-K if dealer upcard is 2 through Q AND matches one of your other cards
- Fold A-K otherwise
This simplified approach costs ~0.1% compared to perfect play.

Real-World Examples
Example 1: Easy Raise
Your Hand: J♠ J♥ 9♣ 5♦ 2♠ Dealer Upcard: K♣
Decision: Raise (pair) Reasoning: Any pair is automatic raise.
Example 2: Easy Fold
Your Hand: K♣ Q♦ 10♥ 7♠ 3♣ Dealer Upcard: A♦
Decision: Fold Reasoning: Less than A-K high, no pair.
Example 3: Tricky A-K
Your Hand: A♠ K♦ 8♣ 6♥ 3♠ Dealer Upcard: 8♥
Decision: Raise Reasoning: A-K with dealer upcard matching one of your cards (8).
Example 4: A-K Fold
Your Hand: A♣ K♠ 9♦ 5♥ 2♣ Dealer Upcard: J♦
Decision: Fold Reasoning: A-K without matching dealer upcard, no Q-J in hand.
Common Caribbean Stud Mistakes
1. Always Raising A-K
Mistake: "A-K is strong, always raise" Reality: A-K without favorable conditions loses money Fix: Follow A-K strategy precisely
2. Folding Small Pairs
Mistake: "Deuces can't win" Reality: Any pair beats no pair; dealer often doesn't qualify Fix: Always raise any pair
3. Chasing the Progressive
Mistake: Betting $1 every hand Reality: Costs $60+/hour with negative EV Fix: Only bet progressive at $250K+ jackpots
4. Ignoring Dealer Non-Qualification
Mistake: Celebrating wins when dealer doesn't qualify Reality: Raise only pushes, missing value Fix: Understand this is normal (44% of time)
Frequently Asked Questions
Why is the house edge so high?
Because you must decide before seeing dealer's full hand, and raise is 2x ante. Also, raise only pushes when dealer doesn't qualify.
Should I always bet the progressive?
No. The $1 side bet has ~26% house edge at typical jackpot levels. Only +EV above ~$220,000.
Is Caribbean Stud beatable?
No. Unlike blackjack, there's no way to gain an edge. Optimal play minimizes losses to 5.22%.
Why does dealer need A-K to qualify?
This rule gives players some protection—you win ante when dealer has weak hands. It reduces edge from ~7% to 5.22%.
Can I see other players' cards?
Technically against rules, but in practice, sharing information doesn't significantly help due to independent hands.
What's the best Caribbean Stud strategy?
Simple version: Raise pair or better, raise A-K matching dealer upcard, fold everything else.
Advanced Concepts
Variance in Caribbean Stud
| Metric | Value |
|---|---|
| Standard deviation | 2.24 units per hand |
| Variance | High (bonus payouts) |
| Bankroll needed | 100+ units for session |
Element of Risk
The 5.22% edge applies to total action (ante + raise). Effective edge on initial ante is higher due to fold decisions.
Collusion Considerations
In theory, seeing other players' folded cards helps slightly. In practice:
- Casinos prohibit card sharing
- Benefit is tiny (<0.5% edge reduction)
- Not worth the effort
