Caribbean Stud Poker Calculator: Optimal Raise/Fold Strategy

Caribbean Stud combines five-card poker with casino banking. Our calculator shows exactly when to raise, when to fold, and whether that progressive jackpot bet is ever worth it.

What Is Caribbean Stud Poker?

Caribbean Stud is a table game where you play five-card poker against the dealer. You ante, receive five cards, then decide to fold (lose ante) or raise (2× ante). The dealer needs A-K or better to qualify—if not, you win even money on ante only.

Quick Answer: Optimal strategy: raise with A-K-J-8-3 or better, fold worse hands. House edge is 5.22% with perfect play. Raise when you have any pair, or A-K with J+ or matched suit with dealer's upcard. The progressive jackpot bet has ~26% house edge—avoid unless jackpot exceeds ~$260,000 on a $1 bet.

The A-K Decision

A-K hands are the tricky decisions:

RAISE with A-K when:
- 3rd card is J or higher (A-K-J-x-x)
- 3rd card is Q and 4th is 8+ (A-K-Q-8-x)
- Dealer upcard matches one of your cards
- Dealer upcard is 2-Q and you have A-K-Q

FOLD other A-K hands

Real-World Examples

Example 1: Clear Raise

Your hand: J♠ J♥ 9♦ 6♣ 3♠ Dealer shows: K♣ Ante: $10

Analysis:

• You have a pair of Jacks
• Always raise with any pair
• Raise $20

Action: RAISE $20

Example 2: Marginal A-K

Your hand: A♠ K♥ J♦ 7♣ 2♠ Dealer shows: 8♣ Ante: $25

Analysis:

• A-K-J-7-2 vs threshold A-K-J-8-3
• Your 4th card (7) is less than 8
• Close decision

Action: FOLD (barely)

Example 3: Matching Upcard

Your hand: A♠ K♥ 10♦ 5♣ 5♠ Dealer shows: 5♦ Ante: $15

Analysis:

• You have pair of 5s
• Also match dealer's upcard
• Easy decision

Action: RAISE $30

Example 4: Non-Qualifying Dealer

Your hand: A♠ K♥ Q♦ J♣ 9♠ (straight) Dealer shows: 3♣ Dealer hand: Q♥ J♦ 8♣ 4♠ 3♣ (Q high) Ante: $10, Raise: $20

Result:

• Dealer doesn't qualify (no A-K or pair)
• You win $10 on ante (even money)
• Your $20 raise is returned (no action)
• You won a straight but only get $10

This is why dealer qualification hurts big hands

Common Strategy Mistakes

1. Folding All A-K Hands

Mistake: "A-K is too weak to raise" Problem: Some A-K hands have positive raise EV Fix: Learn which A-K hands to raise

2. Raising Every Hand

Mistake: "I paid the ante, I should play" Problem: Weak hands have large negative EV Fix: Fold ~25% of hands

3. Chasing Progressives

Mistake: Always betting the side bet Problem: 26%+ house edge destroys bankroll Fix: Only bet when jackpot exceeds $260K

4. Ignoring Dealer Upcard

Mistake: Not adjusting for dealer's shown card Problem: Matching cards affect strategy Fix: Raise marginal A-K when matching

Standard	30× ante
Aggressive	20× ante

Advanced Concepts

Information Usage

One dealer card visible affects strategy:

If dealer shows card in your hand:
- Less likely dealer has pair
- More likely dealer won't qualify
- Slight raise advantage

If dealer shows A or K:
- Dealer more likely to qualify
- Adjust threshold slightly tighter

Composition-Dependent Strategy

A♠-K♥-J♦-8♣-3♠ vs A♠-K♥-J♦-8♣-3♣

Both are A-K-J-8-3, but:
- First has no flush possibility
- Second has 3 clubs

Minimal difference, use basic strategy

Collusion Impact

In theory, seeing other players' cards helps:
- Know which cards aren't in dealer hand
- Slightly adjust qualifying probability

Casinos prevent by face-down dealing
Practical advantage: negligible

Frequently Asked Questions

Why is the house edge so high?

Dealer qualification rule. When dealer doesn't qualify, you only win ante (even money) regardless of your hand strength. This turns winning straights/flushes into minimum wins.

Should I show my hand?

Rules vary. Some casinos allow it, some don't. No strategic advantage either way since no player collusion is possible.

Is card counting possible?

Minimally. Seeing other players' cards provides tiny edge (0.1-0.2%) but casinos prevent by face-down dealing.

What if dealer and I have same hand?

Compare by poker rules. Highest card wins, suits don't matter. True ties push.

Is the game beatable?

Not without cheating or dealer errors. 5.22% edge is significant. Play for entertainment, not profit.

Best seat at the table?

Doesn't matter mathematically. Some prefer last seat to see other cards longer, but advantage is negligible.
