Novice players ask: “How do my Aces do against Kings?”
Pro players ask: “How does my specific hand perform against his 15% 3-bet calling range on a 9-8-7 flush-draw board?”
Standard odds calculators tell you preflop percentages. But poker is played postflop, where the board texture changes everything. Our Postflop Range Equity Calculator is an advanced solver-lite tool. It allows you to pit a specific hand (or an entire range) against an opponent’s range, accounting for Card Removal effects and board texture to calculate your true equity.
Postflop Range Equity
SimulatorHow to Use the Calculator
This tool visualizes the “Range War” between two players. Here is how to set up a simulation:
- Define Hero’s Range:
- You can select a specific hand (e.g., click specific cards in the matrix until only one combo remains) or set a percentage (e.g., Top 15% opening range).
- Define Villain’s Range:
- This is the most critical step. If an opponent plays tight, set the slider to 10-15%. If they are loose, set it to 30-50%.
- Use the “Edit Range” button to manually exclude hands. For example, if you know they would have 4-bet with AA/KK, remove those hands from their calling range.
- Input the Board:
- Enter the Flop, Turn, or River cards.
- Note: The calculator automatically removes these cards from the players’ ranges (Card Removal). If the Ace of Spades is on the board, neither player can have it in their hand.
- Analyze Equity: The result shows who has the mathematical advantage on that specific board texture.

Real-World Examples: Range Advantage
Why does “Range vs. Range” matter more than “Hand vs. Hand”? Because you never know exactly what your opponent has.
Example 1: The “Range Disadvantage”
Hero (UTG): Opens Top 10% (AA-88, AK-AQ).
Villain (BB): Calls Top 40% (Wide defense).
Board: 6♣ 5♣ 4♦.
- The Analysis: Even though Hero has the stronger preflop range, this board is a nightmare. The Villain’s wide range contains all the Sets (66, 55, 44), Straights (87, 73), and Two Pairs. Hero’s range (mostly big pairs) is actually an underdog here. This is why you should check back often on low, connected boards.
Example 2: The “Blocker” Bluff
Hero: A♠ K♠ (Flush Draw)
Villain Range: Top 15%
Board: J♠ 8♠ 2♦
- The Analysis: Because you hold the A♠ and K♠, you mathematically block the Villain from having the Nut Flush Draw or the Second Nut Flush Draw. This increases the likelihood that they are holding a weaker hand that will fold to aggression.
Frequently Asked Questions (FAQ)
What is “Card Removal” or “Blockers”?
Card Removal means that if a card is in your hand or on the board, it cannot be in your opponent’s range. For example, if the board is A-A-7, it is statistically very unlikely your opponent has an Ace, because 2 of the 4 Aces are already visible.
What is the difference between this and a Solver (like PioSolver)?
This is an Equity Calculator, not a GTO Solver. It tells you who is winning mathematically (Equity) given the ranges. A Solver goes a step further and tells you how to bet (Strategy/EV). This tool is the foundational step before using complex solvers.
Why does the equity change on the Turn?
Equity is fluid. A “safe” range on the Flop can be destroyed by a Turn card that completes straights or flushes. By inputting the Turn card, the calculator updates the match-up to show how the new card impacts the ranges of both players.
