In poker, you rarely know your opponent’s exact two cards. Instead, you put them on a Range — a set of likely hands based on their position and betting behavior.
Standard odds calculators assume you know the opponent’s cards (e.g., AA vs KK). Solvers are too slow to use during a quick review. Our Hand vs Range Equity Calculator bridges the gap. It allows you to input your specific holding (e.g., As Ks) and run it against a percentage-based range (e.g., Top 15%), instantly showing your win probability while accounting for “Card Removal” effects.
Hand vs Range Equity
CalculatorHow to Use the Calculator
This tool is designed for speed and precision. Follow these steps to analyze a spot:
- Enter Your Hand (Hero): Type in your specific two cards (e.g.,
Ah Khfor Ace-King of Hearts).- Why specific suits? Suits matter for postflop calculations and blocker effects.
- Define Opponent’s Range (Villain):
- Use the “Edit Range” button to select a percentage (e.g., Top 20% for a standard loose opener) or manually click the matrix grid to select specific combos like “Pocket Pairs” or “Suited Connectors.”
- Input the Board (Optional):
- Leave blank for Preflop Equity (e.g., Should I call this shove?).
- Enter Flop/Turn/River cards to calculate Postflop Equity.
- Calculate: The tool runs a Monte Carlo simulation, removing your cards and the board cards from the opponent’s possible range to give you a precise equity percentage.
Related Tools: If you want to compare two ranges against each other (e.g., UTG Range vs BB Defense), use the advanced Range vs Range Equity Calculator. To figure out if the equity you found is enough to make a profitable call, check the Pot Odds Calculator.
Real-World Examples: The Power of Blockers
Why use this tool instead of a standard odds calculator? Because Card Removal changes everything.
Example 1: The “Coin Flip” Myth
Hero: A♠ K♠
Villain Range: Top 5% (QQ+, AK)
You might think AK is a “coin flip” against a tight range. However, because you hold two of the Aces and Kings, you massively reduce the number of combinations of AA and KK the opponent can have. The calculator reveals that against this specific range, your equity is actually about 40%, not 50%. You are a statistical underdog.
Example 2: Postflop Bluff Catching
Board: Q♥ J♥ 4♣ 2♠
Hero: A♥ 10♥ (Nut Flush Draw + Gutshot)
Villain Range: Top 20%
You are facing a bet. You don’t have a made hand, but you have a monster draw. By running this calculation, you might find you have 35-40% equity even against a range of made hands (Top Pair+). This raw equity often makes a call mathematically correct even if you are currently “losing.”
Example 3: Blocking the Nuts
Board: K♠ 8♠ 3♦
Hero: A♠ Q♦
You have Ace High. However, you hold the A♠. This means your opponent cannot have the Nut Flush Draw. When you input this into the calculator, you will see that your equity increases slightly because you have removed the strongest semi-bluffs from their potential range.
Frequently Asked Questions (FAQ)
What is “Card Removal” or “Blockers”?
Card Removal is the concept that if you hold a specific card (e.g., the Ace of Spades), your opponent cannot hold that same card. This reduces the number of strong combinations (like AA or the Nut Flush) in their range. This calculator automatically accounts for this logic.
How do I know what percentage range to give my opponent?
This comes with experience, but here are rough guidelines:
- Tight (Nit): Top 5-10% (Premium pairs and big aces).
- Standard Reg: Top 15-20% (Pairs, broadways, suited connectors).
- Loose/Aggressive: Top 30-50% (Wide variety of playable hands).
Can I use this for Omaha (PLO)?
No, this calculator is specifically for Texas Hold’em. The combinatorics of 4-card hands in Omaha are much more complex. For PLO analysis, please use our dedicated Omaha Equity Calculator.
