Uncapped Range
Also known as: uncapped range, uncapped, nut-uncapped range
A range that still contains the nuts and strongest holdings, letting it credibly threaten and defend against any bet size.
A range is uncapped when it still contains the strongest possible hands — the top of its equity distribution reaches the nuts. Aggressive lines preserve the cap: the 3-bettor preflop, the player who check-raised the flop, or the one who led into a scary board can all credibly hold monsters, so their range is uncapped.
The strategic payoff is leverage. An uncapped range can:
- Defend against overbets without being run over — because it can hold the nuts, it doesn't have to fold its whole top to big sizing, and it can raise for value.
- Apply maximum pressure itself — credibly threaten any size, forcing a capped opponent to defend their bluff-catchers at MDF with no counter-raise.
The asymmetry between capped and uncapped ranges is what drives overbet theory in solvers: big bets flow from the uncapped player toward the capped one. Note that being uncapped isn't automatically range advantage — you can hold a few nutted combos (nut advantage, uncapped) while the opponent has higher average equity. The two edges are distinct and either can justify aggression.
Example
You 3-bet preflop and barrel an A-high flop and turn. By the river your range still includes AA, AK, sets — it's uncapped. That lets you size up to a pot-sized or overbet river: villain knows you can have the nuts, so they can't profitably bluff-raise, and must defend their bluff-catchers at MDF.
