7-Card Stud Equity Calculator

In Texas Hold’em, poker is a game of incomplete information. In 7-Card Stud, it is a game of available information. The difference between a winning Stud player and a losing one is often memory: knowing which cards have already been folded.

Standard poker calculators fail at Stud because they assume a full 52-card deck remains. In a real Stud game, you might see four Spades folded on 3rd Street, which drastically reduces the odds of your opponent making a flush. Our 7-Card Stud Equity Calculator allows you to input these “Dead Cards,” giving you the only mathematical analysis that matters in mixed games.

How to Use the Calculator

To get an accurate result, you must act like a detective. Input every piece of information visible on the table:

1. Enter Hero’s Hand: Input your current cards.
   • Format: Standard notation. Brackets usually denote hole cards, e.g., (Ah Kh) Qs for 3rd Street.
2. Enter Villain’s Hand: Input the cards you can see (their Up-Cards). If you know their hole cards (from a showdown or simulation), enter those too. If you only know their Up-Cards, the calculator estimates their range based on random remaining cards.
3. Enter Dead / Exposed Cards (Crucial): This is the game-changer.
   • Look at the “Door Cards” of players who folded.
   • If you need an Ace to win, but you saw two Aces folded on 3rd Street, enter them here. The calculator will adjust your equity from “Hopeful” to “Drawing Dead.”
4. Calculate: The tool runs a Monte Carlo simulation dealing out the remaining streets (4th through 7th) to determine who wins the pot.

Real-World Examples: The “Dead Card” Effect

Why is memory so important in Stud? Let’s look at how Dead Cards shift the math.

Example 1: The Live Flush Draw

Hero: (A♥ 5♥) K♥ (3 Hearts)
Villain: (x x) Q♠
Dead Cards: None.

• The Math: You are in great shape. Your flush draw is “Live,” meaning all 10 remaining hearts are potentially in the deck.

Example 2: The Dead Flush Draw

Hero: (A♥ 5♥) K♥
Villain: (x x) Q♠
Dead Cards: 2♥, 7♥, 9♥, J♥ (Folded by other players).

• The Math: You still have 3 hearts, but 4 hearts are dead. There are only 6 hearts left in the deck. Your equity plummets dramatically. A standard calculator would tell you to call; our Dead Card calculator tells you to fold.

Example 3: Buried Pairs

You have (Q♠ Q♦) 7♣ (Split Queens). You are up against a player showing an Ace.

• Scenario A: No Aces are dead. Your opponent likely has a higher pair. You are an underdog.
• Scenario B: You saw the other two Aces folded as door cards.
• The Result: It is mathematically impossible for your opponent to have a Pair of Aces. You are now a massive favorite, and you can play your Queens aggressively.
