Range advantage means your entire range of possible hands is stronger than your opponent’s on a given board. The player with range advantage can bet more often and at higher frequency.
Range advantage comes from the preflop action. On an ace-high or king-high board, the preflop raiser usually has more top pairs and overpairs than the caller, so they hold range advantage and can c-bet a wide range. On low, connected boards that hit the caller’s suited connectors, the advantage can flip.
Range advantage justifies frequency (how often you bet), while its cousin the nut advantage — holding more of the very strongest hands — justifies sizing (using big bets and overbets). Reading who owns the board is the first question on every flop.
Range advantage is not the same as nut advantage. On 6♥5♠4♦ the button still has about 52% of the equity — almost the same as on K♠8♦3♣ — but two pair or better is 5.1% of the big blind’s range and only 4.4% of the button’s, so the course checks the button’s whole range there. And it is never about your own two cards: with Q♣J♣ on A♥7♦2♣ you have nothing, yet the bet is made for the range and Q♣J♣ is part of it. Sort the board first, then ask whether your hand is an exception.

FAQ
How do you know who has range advantage?
Ask which player’s preflop range connects better with the board. High, disconnected boards favor the raiser; low, connected boards favor the caller.
Is range advantage the same as nut advantage?
No. Range advantage is overall equity and drives betting frequency; nut advantage is holding more of the top hands and drives big-bet and overbet sizing.
