Why
Final board A♣ 8♦ 5♣ 5♥ 2♠ is paired with the flush missed; the BTN's value is Ax and the occasional 5x/full house, while busted club and straight draws are pure air. Hero holds J♦J♣ = an underpair to the ace, beating only those busted draws — a textbook bluff‑catcher with no value to lead for. Checking OOP takes a free showdown and lets the BTN keep bluffing the missed draws, the only hands hero beats.
Key idea
An underpair on an ace-high paired river is a bluff‑catcher: check it OOP and let air bet into you rather than turning it into a bluff or value bet.
Common mistake
Betting JJ for "value" on an ace board — worse hands never call and you only get raised or called by Ax.
