What Is a Range?
Before diving into range types, the foundation: a range is the complete set of hands a player could hold in a given situation. Rather than trying to put an opponent on one specific hand, thinking in ranges means considering every possible hand they could have — and how often they have each one.
Advanced players ask: “What is my opponent’s range — and how does my hand perform against it?”
For example: a very tight player makes a 4-bet preflop. You know them well enough to say their range is QQ, KK, AA — written as “QQ+”. That list of possible hands is their range. Everything they do at the table narrows or informs that range.
Once you understand what a range is, the next step is understanding how ranges are shaped — and the two fundamental shapes are polarized and linear.
Polarized Range — The Two Extremes
A polarized range contains hands from two opposite ends of the strength spectrum: very strong hands and relatively weak hands — with nothing in the middle.
Think of it as an either/or construction. When you bet with a polarized range, you either have the nuts (or close to it), or you are bluffing with a weak hand. There are no medium-strength, “showdown value” hands in between.

This range contains premium hands (AA, KK, QQ, AK) paired with weak ace-suited bluffs (A2s–A5s). Notice what is absent: no JJ, TT, AQ, KQ — the medium-strength hands are intentionally excluded.
Weak hands: A2s–A5s — bet as bluffs, block opponent’s strong aces
Missing: JJ, TT, AQo, KQs — these are called, not 4-bet
The weak hands chosen as bluffs are not random — A2s–A5s block AA and AK combinations in the opponent’s range, making them ideal bluffing candidates.
A polarized range is most effective when paired with large bet sizes. A big bet with a polarized range forces opponents into difficult decisions: do they call knowing you have either the nuts or air?
Linear (Merged) Range — The Spectrum
A linear range — also called a merged or condensed range — contains hands across the full strength spectrum: strong hands, medium hands, and speculative weaker hands. There is no gap in the middle.
When visualised on a hand matrix, a linear range clusters in one corner — starting from the strongest hands and working downward in a continuous, connected block.

Medium: 88, KJs, QTs — solid playable hands
Speculative: 22, 65s, K5s — included for implied odds and board coverage
No gap. Every tier of hand strength is represented. This is what a linear range looks like in practice.
A linear range works best with smaller to medium bet sizes. You are not trying to blow opponents off hands — you are betting for thin value across a wide, connected range of hands.
Polarized vs. Linear — Side by Side
| Factor | Polarized Range | Linear Range |
|---|---|---|
| Hand composition | Nuts + bluffs only | Strong + medium + weak |
| Middle-strength hands | Excluded | Included |
| Best bet sizing | Large (75–150% pot) | Small to medium (25–66% pot) |
| Primary goal | Fold equity + max value | Thin value, board coverage |
| Common preflop spot | 4-bet range | Open-raise, 3-bet in position |
| Common postflop spot | River overbets | Flop/turn c-bets |
| Opponent’s best response | Exploit by calling with right freq. | Exploit by raising strong hands |
Postflop: Where Range Type Really Matters
Preflop, range construction is largely solved by solvers and training tools. Postflop is where understanding polarized vs. linear ranges becomes a real-time skill.
Big bets on later streets — river especially
- You are the preflop aggressor on a board that heavily favours you — your range has many more strong hands than your opponent’s. Large bets with your nuts, balanced by bluffs, is the correct approach.
- River situations — by the river, draws have either completed or missed. There is no more “medium” — hands are either strong made hands or missed draws. A polarized betting strategy (big bets, nutted hands + bluffs) matches the reality of the situation.
- Overbet spots — betting more than the pot is almost always a polarized action. You are representing the very top of your range.
Smaller bets on earlier streets — flop and turn
- Wet, connected boards where you have range advantage — a small c-bet with a linear range (all your strong, medium, and some weak hands) extracts value from a wide portion of your range at once.
- When you want to charge draws without inflating the pot — a small linear bet accomplishes this efficiently without committing to a large pot with medium-strength hands.
- Heads-up in position — a linear small bet in position keeps the pot manageable and denies free cards while protecting a wide range of hands.
Quick Decision Guide: Which Range Type?
| Situation | Range Type | Bet Size |
|---|---|---|
| Preflop 4-bet | Polarized | ~2.5x the 3-bet |
| Preflop open-raise | Linear | 2–3 BB |
| Flop c-bet (range advantage) | Linear | 25–40% pot |
| Turn barrel on blank card | Depends on board | 50–75% pot |
| River bet (no draws possible) | Polarized | 75–125% pot |
| River overbet | Polarized | 125–200% pot |
| 3-bet in position vs. late position open | Linear | 3x the open |
Range Shape Determines Bet Size. Always.A polarized range demands large bets. A linear range demands small to medium bets. Mismatching the two — large bets with a linear range, or small bets with a polarized range — is one of the most common and costly leaks in poker.
