You will never know your opponent's exact two cards. Strong players gave up on that guessing game years ago. Instead, they assign each opponent a range: the complete set of hands that player can hold given every action taken so far. Then they pick the line that performs best against that entire set, not against one imagined holding.
This guide walks through the whole skill, from reading a poker range chart cell by cell to comparing range vs range on the flop. By the end you will know why AKo is three times as likely as AKs, why some boards belong to the preflop raiser, and how to drill range thinking until it runs on autopilot.
What Is a Poker Range?
A poker range is the full collection of hands a player can hold in a specific spot, based on everything they have done in the hand. Instead of putting an opponent on one hand, you assign them every hand consistent with their actions, then weigh your decision against that whole distribution.
Ranges start wide and narrow with every action. Before the cards are dealt, anyone can hold any of the 1,326 possible two-card combinations. The moment a player open-raises from under the gun at a 6-max table, that set collapses to roughly the top 18% of hands. A call of a 3-bet filters it further. A check-raise on the turn filters it again.
This is why range thinking beats hand reading street by street. A single guess is either right or wrong, and it is usually wrong. A range is never wrong; it just gets sharper as the hand develops. Solvers, the programs that compute game theory optimal strategy, operate purely on ranges. They never ask "what does he have?" They ask "what does his whole range do here, and what is my best response to all of it?"
Three practical payoffs follow directly from thinking this way:
- Better big decisions. Calling a river shove is profitable or not based on how many value combos and bluff combos fit the opponent's line, not on a hunch.
- Built-in balance. When you plan your own play range by range, you stop telegraphing strength, because every action covers strong hands and bluffs alike.
- Cleaner exploits. Once you know what a balanced range looks like, an opponent who 3-bets only premiums or never bluffs rivers sticks out immediately.
How Do You Read a Poker Range Chart?
A poker range chart is a 13x13 grid showing all 169 starting hand types in Texas Hold'em. Pocket pairs run down the diagonal from AA to 22, suited hands sit above the diagonal, and offsuit hands sit below it. Colors mark the action for each hand: raise, call, fold, or a mix.
The geometry takes about two minutes to learn and then never changes. Rows and columns are both ordered from ace down to deuce. To find AKs, go to the A row and the K column, above the diagonal. To find AKo, go to the K row and the A column, below the diagonal. Any cell where row and column match is a pocket pair.
Most charts use a consistent color language. Red or green typically means raise, yellow or blue means call, and gray means fold. When a cell is split between two colors, the hand is played at a mixed frequency: a solver might open K♥7♥ from the hijack 65% of the time and fold it the rest. You do not need to replicate exact mixes at the table. Knowing a hand is borderline is the actionable information.
The Combos Behind Each Cell
Here is the part most players skip, and it costs them. The 169 cells are not equally likely. Each cell represents a different number of real card combinations, and the differences are large.
| Hand category | Hand types | Combos per type | Total combos |
|---|---|---|---|
| Pocket pairs | 13 | 6 | 78 |
| Suited hands | 78 | 4 | 312 |
| Offsuit hands | 78 | 12 | 936 |
| All hands | 169 | – | 1,326 |
Run the numbers and a few facts jump out. Offsuit hands make up 936 of 1,326 combos, about 71% of everything you can be dealt. AKo is three times as common as AKs (12 combos versus 4). And any single pocket pair is rare: you hold AA just 6 times out of 1,326 deals, about once every 221 hands.
This is why a range that looks small on the grid can be large in reality. Adding ATo to a range adds 12 combos; adding A5s adds only 4. Players who eyeball charts without counting combos consistently misjudge how wide their opponents actually are. Our full guide to combo counting turns this into a step-by-step method you can use mid-hand.
The Four Range Shapes: Linear, Polarized, Capped, Condensed
Ranges come in four basic shapes. Linear ranges contain the best hands down to some cutoff. Polarized ranges hold strong hands and bluffs with little in between. Capped ranges have a strength ceiling and cannot contain the nuts. Condensed ranges cluster around medium strength. The shape tells you who can apply pressure.
| Shape | What it contains | Typical example |
|---|---|---|
| Linear | Top X% of hands, no gaps | UTG opening range |
| Polarized | Nutted hands plus bluffs | River overbet range |
| Capped | No nutted hands possible | BB after check-calling twice |
| Condensed | Mostly medium-strength hands | Preflop caller on a low board |
Shape drives sizing. A linear range wants small bets at high frequency because almost everything in it benefits from folds and thin calls. A polarized range wants big bets, since its strong hands extract maximum value while its bluffs generate maximum fold equity. The full breakdown lives in our guide to polarized vs merged ranges.
Capped ranges are the ones to hunt. A player who check-calls flop and turn on a dry board almost never holds a set or better, because those hands would have raised earlier for protection and value. Solvers attack that ceiling relentlessly, which is exactly why overbets show up so often on rivers against capped calling ranges.
How Do You Build Preflop Ranges by Position?
Preflop ranges are built around position. Open tight in early seats and widen toward the button. At a 100bb 6-max cash table, solver-derived ranges open roughly 18% of hands under the gun, 22% from the hijack, 28% from the cutoff, and about 43% on the button.
The logic is simple: every player left to act behind you is a chance someone wakes up with a premium, and every postflop street you play out of position costs you EV. The button opens more than twice as many hands as UTG for those two reasons alone. If position concepts feel fuzzy, start with our position strategy guide before memorizing charts.
A few construction principles keep ranges coherent across positions:
- Suitedness earns its slot. Suited hands carry roughly 3-4% more equity than their offsuit twins, plus nut potential. That is why K9s opens from UTG in most solver outputs while K9o folds.
- Hands must survive a 3-bet. Early-position opens face 3-bets from five potential opponents. Hands like QTo that play terribly against a reraise get cut first.
- Stack depth shifts the mix. Deep stacks favor suited connectors and small pairs for implied odds. Short stacks favor raw high-card strength because pots end sooner.
- Blocker value matters at the margins. A5s makes UTG ranges partly because holding an ace makes it less likely opponents hold AA or AK. Our blockers and unblockers guide covers why.

Range vs Range: Who Has the Advantage Postflop?
Range vs range analysis compares how two complete ranges interact with a board, instead of pitting one hand against another. The player whose range holds more total equity has the range advantage. The player whose range holds more nutted combos has the nut advantage. They are not always the same player.
Range advantage is about average equity. On A♠K♥4♦ after a button open and a big blind call, the button's range is stacked with AK, AQ, AA, KK, and broadway combos the big blind would have 3-bet or folded preflop. Run the two ranges against each other and the button sits near 58-60% equity. Solvers respond with small bets at very high frequency, because nearly the entire range profits from charging the weaker distribution.
Nut advantage is about the top of the ranges. Flip the board to 6♠5♠4♥ and the picture inverts. The big blind's calling range is full of 87s, 75s, 53s, and small pairs that just became straights, two pairs, and sets, hands the button mostly does not arrive with. Even if raw equities run close, the big blind owns the nutted region and can start check-raising and betting big. Whoever holds the nut advantage controls the large sizings; whoever holds only the equity advantage has to stay modest.
Two questions sort almost every flop in a few seconds:
- Whose range has more overall equity here? High and broadway-heavy boards favor the raiser. Low, connected boards favor the caller.
- Who can hold the nuts, and who cannot? Count the sets, straights, and strong two pairs each range actually contains. A range that cannot hold them is capped and should defend, not attack.
Practice this comparison deliberately. Pick a preflop matchup, deal a flop, and before looking at any solver output, decide who has the range advantage and who has the nut advantage. Then check. GTO Gecko's library includes true 3-way multiway postflop solutions alongside heads-up pots, so you can test your reads in the messy multiway spots where most players are guessing.
How Do You Practice Thinking in Ranges?
Range thinking becomes automatic through reps, not reading. The fastest route: memorize the opening grids, narrate opponents' ranges out loud while you play, count combos on big rivers, and drill solver spots until your frequencies converge. Most players see clear improvement inside two to three weeks of daily practice.
Here is a routine that works:
- Learn the preflop grids cold. Start with the six opening ranges for your format. Quiz yourself on borderline hands: is 97s a hijack open? Is ATo an UTG open? The free range library answers every one of these instantly.
- Narrate ranges in real time. Every hand you play or watch, state the preflop range out loud or in your head, then update it on each street. "He called the cutoff open from the button: pairs, suited broadways, suited connectors, some AQo and AJo." This is the core habit.
- Count combos on rivers. When a big bet lands, count the value combos that fit the line, then the plausible bluffs. Compare the ratio to the pot odds. This single habit fixes more bad calls and bad folds than any other.
- Drill against a trainer that punishes your leaks. GTO Gecko's preflop, postflop, and full-hand trainers track your ELO and re-serve the exact spots you misplay until you fix them. The explainability engine then tells you in plain English why the solver action is right, so you learn the pattern instead of memorizing the answer.
- Review hands range vs range. In your session reviews, resist the urge to ask "was my hand good enough?" Ask "what does my whole range want to do here?" instead. That one reframe is the difference between solver-era poker and 2010 poker.
The free tier covers the on-ramp: full preflop range library browsing plus daily free trainer hands, no credit card required. Use them to find out where your preflop game actually stands before you spend a dollar on study tools.
Poker Range FAQ
What does range mean in poker?
A range is every hand a player can realistically hold in a given situation, based on their actions so far. A tight player's under-the-gun raise might represent a range of AA-77, AK-AJ, KQ, and strong suited hands. Skilled players make decisions against this whole set rather than guessing one specific hand.
How many combinations are in a poker range?
There are 1,326 possible two-card combinations in Texas Hold'em, grouped into 169 hand types. Each pocket pair has 6 combos (78 total across 13 pairs), each suited hand has 4 combos (312 total), and each offsuit hand has 12 combos (936 total). A "20% range" therefore contains roughly 265 combos.
How do you read a poker range chart?
Find the diagonal first: it holds the 13 pocket pairs from AA down to 22. Everything above the diagonal is suited, everything below is offsuit. Locate a hand by its row and column, then read the cell's color for the action: raise, call, fold, or a split cell for mixed frequencies.
What is the difference between a polarized and a linear range?
A linear range takes the strongest hands down to a cutoff with no gaps, like an opening range built from the top 20% of hands. A polarized range contains very strong hands and bluffs with the middle removed, like a river overbetting range. Linear ranges prefer smaller bets; polarized ranges justify bigger ones.
What is range advantage in poker?
Range advantage means your entire range has more equity than your opponent's on a given board. It usually belongs to the preflop aggressor on high-card flops. It differs from nut advantage, which measures who holds more of the strongest possible hands. Range advantage supports frequent small bets; nut advantage supports large ones.
How can I practice poker ranges for free?
Browse complete solver-derived preflop charts in GTO Gecko's free range library for every position in Cash, MTT, and Spin and Go formats, then use the daily free trainer hands to test yourself against the solutions. The free tier is permanent and needs no credit card, so daily range drills cost nothing.
Stop Guessing Hands, Start Assigning Ranges
Every concept in modern poker sits on top of ranges. Bet sizing, bluff selection, blocker logic, board coverage: none of it makes sense hand by hand, and all of it snaps into focus range by range. The grid is small, the math is fixed, and the four shapes repeat in every session you will ever play.
The work is the reps. Learn the grids, narrate ranges while you play, count combos when it matters, and check your instincts against real solutions. Open the free range library on GTO Gecko, pick the position you butcher most often, and start there. Your next session will already look different.
