Poker Ranges Explained: What Is a Range and How to Use It
Last updated: May 11, 2026
A poker range is the complete set of hand combinations a player can hold at a given point in the hand — not one specific hand, but every possible hand weighted by likelihood. There are exactly 1,326 possible starting hand combinations in Texas Hold'em, and mastering range thinking means knowing how many combos each hand type contains (pocket pairs have 6, any non-paired hand has 16), how to assign ranges by position, and how to narrow them street by street as new information arrives.
What Is a Range in Poker?
A range is the complete set of hand combinations a player can logically hold in a specific situation, based on all observable actions up to that point. In a 52-card deck, there are exactly 169 unique starting hand types (13 pocket pairs, 78 suited non-paired hands, and 78 offsuit non-paired hands) and 1,326 total starting hand combinations. A player's range at any moment is a subset of those 1,326 combos, filtered by what their actions make plausible.
The reason we use ranges instead of single hand reads is simple: you cannot know your opponent's exact cards. Assigning a single hand to an opponent is almost always wrong, and betting based on that guess is exploitable. Ranges force you to think probabilistically — you act in a way that is profitable against the entire distribution of hands your opponent can hold, not just the one you imagined.
For example, a tight UTG open in a 9-handed game might represent roughly 5% of all starting hands — about 67 combinations, typically TT+, AQs+, AJs, KQs, AQo, AKo. A loose button open might represent 45% — over 590 combinations. The gap between those two ranges dictates very different postflop strategies.
169 unique hand types × average combos per type = 1,326 total combinations
C(52, 2) = 52 × 51 / 2 = 1,326 — the mathematical foundation of range theory
Every action your opponent takes — limping, raising, 3-betting, checking, betting, calling, folding — removes certain hand categories from their range and keeps others. Thinking in ranges means continuously updating this set of possible hands from the first preflop action all the way to the river showdown.
Hand Combinations: The Math Behind Ranges
Range analysis requires counting combinations precisely. Every pocket pair has exactly 6 combos — from the formula C(4,2) = 4!/(2!×2!) = 6, since you choose 2 cards of the same rank from 4 available suits. Every non-paired hand has exactly 16 combos — 4 suited (matching suits) and 12 offsuit (mismatching suits, calculated as 4×4=16 minus 4 suited). All 1,326 possible starting hands derive from C(52,2) = 1,326.
Combination Formulas
Pocket pairs: C(4,2) = 6 combos per pair
Suited non-pairs: 4 combos (one per suit)
Offsuit non-pairs: 4 × 4 − 4 = 12 combos
Total deck: C(52,2) = 1,326 starting hand combinations
The practical payoff: when an opponent 3-bets and you think they have only AA or KK, that's 12 total combinations out of 1,326 — less than 1% of all hands. Even a hand like QQ+, AK totals only 6+6+6+16 = 34 combos. Counting combos prevents you from over-estimating how often an opponent holds a specific premium and lets you calibrate calls and folds with numerical accuracy.
How to Assign a Preflop Range by Position
Position is the single most powerful filter for assigning a preflop range. GTO solvers consistently show that UTG (under the gun) in a 9-handed game should raise first-in with roughly 15% of all hands — approximately 200 combinations. As position improves, ranges widen dramatically: the button opens around 45% of all hands (about 600 combos), and the big blind defends roughly 35–45% against a button open.
UTG (Under the Gun)
~15%
~200 combos
TT+, AJs+, KQs, AQo+, AKo — premium hands only
MP (Middle Position)
~22%
~290 combos
99+, ATs+, KJs+, QJs, AJo+, KQo — slight widening
CO (Cutoff)
~30%
~400 combos
77+, suited aces, suited broadway, A9o+, KJo+ — connectors enter
BTN (Button)
~45%
~600 combos
55+, any suited ace, many broadways, suited connectors — very wide
BB (Big Blind — defense vs BTN)
~40%
~530 combos
Defend wide due to pot odds; include many offsuit hands and small pairs
RFI (raise first in) charts encode these ranges. When you see an opponent open from UTG, you immediately know to exclude all speculative hands from their range. When they open from BTN, almost half the deck is in play. This positional framework is your starting point for every postflop decision — get preflop range assignment right and every subsequent street becomes easier to analyze.
Narrowing a Range Street by Street
Every street of betting is a Bayesian update: new information (a bet, a check, a raise, a fold) removes certain hand combinations from your opponent's range and makes others more likely. By the river, a well-tracked range can be narrowed from 200+ combos to just a handful of specific hand categories. Each action carries a different eliminating power.
Worked Example — UTG vs BTN, Board: K♠7♦2♣ (rainbow)
Preflop — UTG raises, BTN calls
UTG: ~200 combos (TT+, AQs+, AKo…). BTN: ~350 combos (55+, suited aces, broadways)
Approx combos remaining: ~200 / ~350
Flop (K♠7♦2♣) — UTG bets 60% pot, BTN calls
UTG removes most draws that would fold; keeps KK (3 combos), AK (12 combos), TT-QQ, some bluffs. Removes AA raises. BTN: keeps KQ, K9s, 77 (3 combos), 22 (3 combos), some gutshots
Approx combos remaining: ~90 / ~60
Turn (blank: 4♥) — UTG checks, BTN bets 70% pot
UTG check removes monster hands (they'd likely bet KK, AK for value). BTN bet removes weak showdown hands. BTN range now: sets (77/22), two-pairs (K7s, K2s), KQ for value — plus some bluffs
Approx combos remaining: ~50 / ~25
River (8♠) — UTG check-folds
BTN range at time of decision: 6 combos of sets + 4 combos of two pair + bluffs. UTG determines calling is -EV against this distribution.
Approx combos remaining: Decision point
The key principle: aggressive actions (bets, raises) narrow a range toward strong made hands and bluffs, removing medium-strength hands that would check or call passively. Passive actions (checks, calls) narrow a range toward medium-strength hands and draws, removing premium hands that would typically bet for value. By the river, 4 streets of narrowing can compress a starting range of 200+ combos down to fewer than 20 relevant combinations.
Value Ranges vs. Bluff Ranges — Balance and Ratios
A balanced betting range contains both value hands (hands that want to be called) and bluffs (hands that benefit from folds), in a ratio determined by your bet size. This ratio is derived from pot odds math: your opponent must be indifferent to calling or folding at equilibrium, which means your bluff-to-value ratio must exactly match the pot odds you are giving them.
GTO Bluff-to-Value Ratios by Bet Size
1/3 pot bet
3 value : 1 bluff
Opponent needs 25% equity to call
1/2 pot bet
2.5 value : 1 bluff
Opponent needs 25% equity to call
2/3 pot bet
2 value : 1 bluff
Opponent needs ~29% equity to call
Pot-sized bet
1.5 value : 1 bluff
Opponent needs 33% equity to call
2× pot (overbet)
1.25 value : 1 bluff
Opponent needs ~40% equity to call
In practice, a 2/3-pot bet on the river requires 2 value combos for every 1 bluff combo. If you have 12 combos of the nut flush for value, you can include 6 combos of bluffs (hands with no showdown value but good blocking properties) and remain balanced. Including more than 6 bluffs makes you over-bluffing — exploitable by calling stations. Including fewer makes you under-bluffing — exploitable by folders.
This balance principle explains why GTO strategy is not about bluffing randomly — it is about selecting the right number of bluff combos to include in your range, ideally choosing hands that block your opponent's calling hands (nut blockers) and unblock their folding hands (low blockers). Range composition, not individual hand strength alone, determines the profitability of each bet.
Blockers and Their Effect on Ranges
A blocker is any card in your hand that removes combinations from your opponent's range. Because each card exists only once in the deck, holding it means your opponent cannot hold any hand that contains that card. This shrinks the number of combos available in their range by a calculable amount — typically 25–50% for the affected hand type.
Blocker Examples
You hold A♥
Opponent cannot have A♥K♥ (nut flush draw in hearts). AKs reduced from 4 to 3 combos (−25%).
You hold K♠K♥
Opponent cannot hold KK with either of your cards. Sets of kings reduced from 3 remaining combos to just 1 combo (K♦K♣). That is a 67% reduction.
You hold A♠ on a spade flush board
Opponent cannot hold A♠X♠ (the nut flush). This removes the strongest calling hand from their range — ideal blocker for a river bluff.
You hold 9♣ on a 9-8-7 board
Opponent cannot hold 9-9 (set of nines). Reduces their value combos by 3, making their range slightly weaker on this board.
The practical application of blocker theory is in selecting which hands to use as bluffs. On a K♠Q♠J♠ board, bluffing with A♠X is more effective than bluffing with a non-spade hand: you block the nut flush (A♠K♠, A♠Q♠, A♠J♠) from your opponent's value range, making it less likely they hold the nuts when they call. This is called the nut blocker effect.
Blockers also work in reverse — “unblocking” your opponent's folding range. Bluffing without holding cards that appear in your opponent's strong calling range means their calling hands are more numerous, which is bad. Conversely, holding cards that appear in your opponent's folding range (hands they cannot call with) increases the effective fold percentage of your bluff.
How to Start Thinking in Ranges (Practical Tips)
Range thinking is a learnable skill that improves dramatically with focused practice. Three concrete drills will accelerate your development from single-hand guessing to genuine range analysis in as few as 20 dedicated sessions of review. Each drill targets a different aspect of range construction and narrows a specific cognitive gap.
Drill 1: Count combos before each street
Before acting on every street, pause and count the number of combos in your opponent's range that beat you, are ahead of you, and are behind you. Start with preflop: if opponent 3-bets, assign a range (e.g., QQ+, AK) and count: 6+6+6+16 = 34 combos. As the hand progresses, subtract combos eliminated by each action. After 4–6 sessions of doing this live, combo counting becomes automatic and your decisions become mathematically grounded.
Drill 2: Use a hand matrix to visualize ranges
The 13×13 hand matrix (pocket pairs on the diagonal, suited hands above, offsuit hands below) gives you a visual representation of all 169 hand types. Practice shading the matrix for each position — UTG, CO, BTN — to internalize what 15%, 30%, and 45% of hands looks like visually. When you see a villain act from a position, you can mentally visualize their matrix and quickly identify what hand categories are included. Many free range visualizers exist online to practice this drill off-table.
Drill 3: Track how each bet or check updates the range
After a session, review 3–5 hands and write down: what was villain's range preflop, then update it after flop action, turn action, and river action. For each action, note which hand categories you removed and which you kept. Compare your final range estimate with the hand villain actually showed at showdown. Over time, you will build intuition for which actions signal which hand types. Aim to narrow your range estimate to within 10–15 combos of the actual range by the river — that level of precision is achievable and represents a major skill threshold.

Frequently Asked Questions
What is a range in poker?
A range in poker is the complete set of every possible hand combination a player can hold at a given decision point in the hand. Rather than trying to guess the single exact hand your opponent holds — which is impossible without seeing their cards — you assign them a range of hands they would logically play that way based on position, bet sizing, and prior action. Ranges are typically expressed as a percentage of all 1,326 possible starting hand combinations or as specific hand categories. For example, after a tight UTG raise in a 9-handed game, your opponent's range might be TT+, AQs+, AKo — roughly 5% of all starting hands, or about 67 total combinations. Every decision you make at the table should be based on what is profitable against that range as a whole, not against a single imagined hand.
How many combinations does a pocket pair have?
Every pocket pair has exactly 6 combinations, without exception. The math comes from combinatorics: there are 4 cards of each rank in a deck (one per suit), and you need to choose 2 of them, giving C(4,2) = 4! / (2! × 2!) = 6. For aces specifically, the 6 combinations are A♠A♥, A♠A♦, A♠A♣, A♥A♦, A♥A♣, and A♦A♣. The same applies to every pair: QQ has 6 combos, TT has 6 combos, 22 has 6 combos. With 13 possible pocket pair ranks and 6 combos each, there are 13 × 6 = 78 total pocket pair combinations in a full deck. This is important for range construction: when an opponent 4-bets and you put them on AA or KK, that is only 12 combined combos — a very small slice of all 1,326 possible hands.
How many combinations does AK have?
AK has 16 total combinations: 12 offsuit (AKo) and 4 suited (AKs). For AKo, you have 4 aces and 4 kings, giving 4 × 4 = 16 possible pairings, but you subtract the 4 suited combinations (A♠K♠, A♥K♥, A♦K♦, A♣K♣) to get 12 offsuit combos. For AKs, there are exactly 4 combinations — one for each suit. This 16-combo rule applies to every non-paired hand: AQ has 16 combos, KQ has 16 combos, 87 has 16 combos. The 12/4 split between offsuit and suited is always the same. This is useful in practice: if you block one of the aces (say you hold A♥), then your opponent can only have 3 AKs combos (not 4) and 9 AKo combos (not 12), for a total of 12 AK combos instead of 16 — a 25% reduction.
How do you put an opponent on a range?
Putting an opponent on a range is a systematic street-by-street process of elimination. Step 1 — Preflop action: Start with a positional baseline. A UTG raise in a 9-handed game suggests a tight range of roughly 15% of hands (~200 combos); a BTN open suggests a wide range of 40–50%. Step 2 — Flop action: Each action removes hand categories. If your opponent check-calls a flop bet, you can remove most sets and two-pairs (they would likely raise), narrowing the range toward top pairs, draws, and medium-strength hands. Step 3 — Turn action: A check-call again on a blank turn further eliminates very strong hands and weak draws that would give up. Step 4 — River action: By the river, the range is narrow enough that you can often put your opponent on 2–4 hand categories and make a mathematically sound decision. For example: villain raises UTG, calls your 3-bet preflop, check-calls flop and turn on K-7-2 rainbow, then bets river. You can now confidently assign a range of KK (2 combos, missed trips on dry board), KQ-KJ (16 combos of top pair), and a few bluffs.
What percentage of hands should I play preflop?
The correct preflop range depends entirely on your position at the table. Under the gun (UTG) in a 9-handed game, GTO solvers recommend opening roughly 15–18% of hands, approximately 200–240 combos out of 1,326. This includes hands like TT+, AJs+, KQs, AQo+, and KQo. In middle position (MP) you widen slightly to 20–25%. From the cutoff (CO) you can open about 28–32%. The button (BTN) is the widest RFI position at 40–50% — roughly 530–660 combos. From the small blind (SB) you open around 35–40% but face positional disadvantage postflop. Big blind defense (BB) is the most nuanced spot: you should defend 35–45% of hands against a BTN open because you are getting favorable pot odds (already invested 1 big blind). The overarching rule is: tighter from early position, wider from late position, widest from the big blind when facing raises, because you are closing the action with a price discount.
What is the difference between a value range and a bluff range?
A value range consists of hands that want to be called by your opponent's continuing range because they have enough equity to profit at showdown — for example, top pair top kicker, two pair, sets, and straights. A bluff range consists of hands that cannot win at showdown but benefit from fold equity — the extra value gained when your opponent folds. In a balanced (GTO) strategy, you must combine both into a polarized betting range. The ratio of value combos to bluff combos is determined by your bet size relative to the pot. A 2/3-pot bet requires your range to contain approximately 2 value combos for every 1 bluff combo, making your opponent indifferent to calling or folding. A pot-sized bet requires roughly 1.5 value combos per bluff combo. A 1/3-pot bet allows up to 3 value combos per bluff combo. This mathematical relationship — derived from pot odds — prevents your opponent from profitably exploiting your betting range regardless of which hands they hold. Hands chosen for bluffing are typically selected for their blocker properties or future equity, not randomly.
How do blockers affect range decisions?
Blockers reduce the number of combinations of specific hands in your opponent's range by removing cards they would need. When you hold the A♥, your opponent cannot hold A♥K♥ (the nut flush draw in hearts) — you block that combo entirely. When you hold K♠K♥, you block 5 of the 6 possible KK combinations from your opponent's range, leaving only K♦K♣. This is extremely powerful on boards where sets of kings would normally be a strong part of villain's range: instead of 6 combos of KKK, they can have at most 1 combo. Nut blockers are especially valuable in bluffing situations: holding the A♠ on a spade-flush board blocks the nut flush (A♠X♠) from your opponent's range, meaning they are less likely to call you with the absolute best hand — making your bluff more profitable. Conversely, reverse blockers help identify value bets: if you hold K♥Q♦ and block KQ combos, your opponent cannot have KQ, so their range skews toward hands that might call your value bet with worse holdings.
