A range in poker is the complete set of possible hands a player could have in any given situation, based on their actions, position, and playing style. Think of it as your poker playbook, the universe of hands you’d play from each position and how you’d play them.
In modern poker, thinking in ranges rather than trying to put opponents on specific hands is fundamental to profitable decision-making. When you raise from under the gun, your range might include premium pairs (AA-TT), strong broadway hands (AK, AQ), and suited connectors (87s-JTs). Your opponents know this, just as you can deduce their likely holdings from their actions. This range-based thinking forms the foundation of both exploitative play and game theory optimal (GTO) strategies.
The concept evolved from simple hand reading to sophisticated range construction as poker strategy advanced. Today’s players use software to analyze optimal ranges for every position and situation, creating balanced strategies that are difficult to exploit.
How to Calculate Range
Range calculation starts with understanding hand combinations. In hold’em, there are 1,326 possible starting hands:
- 6 combinations of each pocket pair (like AA)
- 16 combinations of each unpaired hand (4 suited, 12 offsuit)
- 4 combinations of each suited hand
To express a range as a percentage, divide the number of hand combinations by 1,326. For example, if you’re playing 200 combinations, that’s 200/1,326 = 15% of hands.
Example 1: Basic Calculation
You open-raise from the button with the top 40% of hands. That’s 530 combinations (40% × 1,326). This includes all pairs, all suited aces, most broadway hands, many suited connectors, and strong offsuit holdings down to about K9o.
Example 2: Range Narrowing
The board comes A♥K♠Q♣. Your opponent, who called from the big blind, suddenly leads out. Their preflop calling range was perhaps 35% of hands. But which hands in that range bet this board? Two pair (AK, AQ, KQ), sets (QQ), straights (JT), and draws (JTs) make up maybe 8% of their preflop range, roughly 106 combinations.
Practical Applications
Decision Making
Ranges transform your decision process from “what specific hand does villain have?” to “how does my hand perform against their entire range?” With Q♣Q♦ facing a turn raise, you’re not trying to decide if they have specifically AA or AK. You’re calculating how QQ performs against all hands that take this action.
EV Calculation
Expected value calculations require range analysis. If the pot is $200 and villain bets $100, you need $100 to win $300. That requires 25% equity. Calculate your equity not against one hand, but their entire betting range. If you have 30% equity against their range, it’s a profitable call.
EV = (0.30 × $300) , (0.70 × $100) = $90 , $70 = +$20
Solver Perspective
Solvers build ranges by finding the game theory optimal frequency for each hand in each situation. They balance ranges to prevent exploitation, if you only 3-bet AA-QQ, opponents fold everything worse. So solvers add bluffs (A5s) and merged hands (AQs) to make your strategy unexploitable.
Common Shortcuts
The “top X%” shortcut helps visualize ranges quickly:
- Top 5% ≈ 66 combos: 88+, ATs+, AJo+, KQs
- Top 10% ≈ 133 combos: 55+, A8s+, ATo+, KTs+, QJs
- Top 20% ≈ 265 combos: 22+, A2s+, A8o+, K8s+, KJo+, suited connectors
Interaction with Other Concepts
Ranges connect every poker concept. Pot odds tell you the required equity; ranges let you calculate if you have it. Position affects ranges, you play tighter from early position. Board texture impacts how ranges interact, some boards favor the preflop raiser’s range.
Pro Tip: When constructing ranges, start with position-based templates then adjust for specific opponents. A standard button opening range might be 40%, but against a 3-bet-happy big blind, tighten to 30% and strengthen your calling range.
When Does Range Matter?
Range thinking matters in every poker decision, but becomes crucial in these situations:
Preflop Construction
Building balanced opening ranges prevents opponents from exploiting you. From UTG, a 12% range keeps you strong. From the button, 40-50% steals blinds while maintaining board coverage.
Postflop Range Advantage
Certain boards favor specific ranges. On A♠K♦5♣, the preflop raiser has more AK, AA, KK in their range. This “range advantage” justifies frequent continuation betting.
Bluff Selection
Choosing bluffs requires range thinking. You need hands that can improve (like flush draws) but aren’t strong enough to call. This creates a balanced range where opponents can’t profitably call or fold everything.
Multi-Street Planning
Ranges evolve street by street. If you bet flop and turn, your river range is stronger (polarized to value and bluffs). Understanding range narrowing helps plan entire hands.
Common Mistakes with Range
Thinking Too Narrow. Many players assign opponents a single hand (“he must have AK”) instead of considering their entire range. This leads to poor decisions when the opponent shows up with unexpected holdings.
Static Ranges. Ranges aren’t fixed, they adjust based on action. A player who calls flop and turn has a different range than their starting range. Update your assessment as the hand progresses.
Ignoring Position. Position dramatically affects ranges but players often miss this. The same player opens 15% from UTG but 40% from the button. Always factor position into range construction.
Don’t Confuse With…
Range vs Hand Reading
Hand reading tries to narrow opponents to specific hands using tells and betting patterns. Range analysis considers all possible hands weighted by probability. Modern poker favors range thinking, though live reads still matter.
Range vs Equity
Your range is what hands you could have. Your equity is how often your actual hand wins against opponent’s range. A range is a set of hands; equity is a percentage.
Hear It at the Table
Key Takeaway
A range represents all possible hands in a player’s strategy for a specific situation. Mastering range construction and analysis transforms poker from a guessing game into strategic warfare, where you make decisions based on the entire spectrum of possibilities rather than hoping to pinpoint exact holdings.
