What Is a Condensed Range in Poker?

A condensed range is one packed with medium-strength hands and nothing else. The very strongest holdings have already left by raising, the weakest have already left by folding, and what remains is a thick block of second-best hands that can call a bet but never welcome a big one. It is the mirror image of a polarized range, which holds only the nuts and air.

Where condensed ranges come from

A range condenses whenever the top and the bottom leave through different exits. Preflop is the cleanest case. You open the BTN to 2.5bb, the BB three-bets to 10bb, and you four-bet A♠A♦ or K♥K♣ while folding J♦7♦ without a thought. What is left to call — TT, JJ, A♠Q♠, K♥Q♥ — is condensed by definition.

Postflop the same thing happens one street at a time. A player who calls the flop, calls the turn, then checks the river has usually raised their sets somewhere along the way and given up with their busted draws. Top pair with a mediocre kicker sits in the middle, and the middle is all that survives.

Condensed against polarized

	Condensed	Polarized
Contents	Medium-strength hands	Nuts and bluffs
Typical action	Calls, checks, small bets	Raises, big bets, overbets
Preferred size	Small, high frequency	Large, low frequency
Comes from	Flatting a raise, checking back	Three-betting, check-raising

Bet sizing follows range shape, which is why the distinction earns its keep. A polarized range wants large bets: the nuts get paid off and the bluffs buy maximum fold equity. A condensed range wants small ones, because every extra chip risks folding out the worse hands you are trying to keep in.

Condensed ranges bet small and often. Polarized ranges bet big and rarely.

Playing your own condensed range

Bet small, bet often, or check. You are collecting thin value from worse pairs and denying equity cheaply, not blowing anyone off a hand you cannot beat anyway.

Know where your ranges condense before the flop is dealt. The solver-built preflop charts show which hands four-bet, which call and which fold, and that calling band is exactly the condensed portion you will be defending on every later street.

Attacking a condensed range

Use size, because your opponent cannot hold the nuts. Overbet the river when their range is a wall of one-pair hands: they must either call wide with a hand that beats nothing you are betting, or fold and hand you the pot. MDF says defend pot/(pot+bet), and against a bet of $150 into $150 that means folding half the time — but a condensed range rarely finds enough hands willing to do it.
