♠ Polarized vs linear range: when to use each

You are on the button, the big blind checks a river of K-8-4-2-9, and you have to decide how much to bet. Some hands in your range made the straight, some are a pair of eights, and plenty are missed draws. If you bet the same size with everything, your opponent cannot read you, but you are not getting the most out of any single hand either.

This is where one idea separates players who bet out of habit from players who bet with a plan: the shape of your range. A range can be polarized or linear, and each shape calls for a different bet size.

What a polarized range is

A polarized range has hands at both ends and almost nothing in the middle. On one side, very strong hands that want to get paid. On the other, bluffs that never win at showdown. Medium-strength hands, which win sometimes and lose sometimes, are left out: with those you check or call.

Because the range has no medium hands, it wants a big bet. With the strong hand you want the biggest pot possible, and with the bluff you want your opponent to put in a lot to call. A river overbet is almost always a sign of a polarized range.

What a linear range is

A linear range, also called merged, includes the best hands and continues downward without gaps: strong hands, good hands and some medium hands that still have value against what calls you. It carries almost no pure bluffs.

This range wants small or medium bets. The goal is to get called by hands worse than your medium hands. If you bet too big, only better hands call, and your middle pair turns from a value bet into an expensive bluff.

How to tell which shape your range has

• Look at which hands reach this street given how you played earlier. If you checked the flop with your medium hands, your turn betting range becomes more polarized.
• Look at the board. On dry, disconnected boards it is easier to hold medium hands that want to bet small for value.
• Look at your opponent. Against a player who calls a lot, betting linear with medium hands earns more. Against one who folds a lot, polarized bluffs earn more.

Quick sizing examples

Preflop, a standard open from early position is fairly linear: you raise the best hands and continue downward. A 3-bet against a player who calls a lot also works best linear, with hands like AJ or KQ that dominate what calls. Against an opponent who folds a lot to 3-bets, polarizing works better: premium hands plus some bluffs with blockers, such as suited A5.

On the river the difference is clearer. With a polarized range you bet big, around pot or more. With a linear range you bet small, a third or half of the pot, so worse hands pay you.

The most common mistake

The typical mistake is betting big with a linear range. You have top pair with a medium kicker, bet the full pot on the river, and only the better hand calls. It feels like a value bet, but you gave your opponent the perfect spot to play against you.

The opposite mistake exists too: betting small with a polarized range. Your bluff applies no pressure and your strong hand does not collect what it could. Before choosing a size, ask which hands in your range are betting and which worse hands can call.
