Why
River (J♦ 8♠ 5♣ | 9♠ | 2♦): hero's 5♦ pairs the 5♣ for bottom pair of fives (A♦ kicker); only four diamonds total, so no flush. This is a weak made hand / bluff‑catcher — it beats the BB's busted draws but loses to every pair J-x, 9-x, 8-x. Too weak to value-bet against a capped range and lacking blockers to make a good bluff, the correct polar line is to check: give up the betting lead and take the small showdown value the pair retains against missed air.
Key idea
A weak bottom-pair bluff‑catcher checks back on the river: too weak to value-bet, no blockers to bluff — take showdown.
Common mistake
Betting bottom pair as 'thin value' — worse hands (busted air) never call and better pairs never fold, so betting only gets raised or folds out what you beat.
