Bluff-catcher
A hand that beats every bluff in an opponent's range but loses to every value hand in it, so its whole worth depends on how many bluffs that range actually contains.
Calling with a bluff-catcher is never about beating the top of an opponent's range. It is about the range's composition: if the bluffs make up enough of the combinations, a hand that loses to every single value holding can still show a profit, because the pot odds only need to clear the bluff share, not the whole range.
