Why
River, board J‑8‑5‑9‑2: hero's A‑5 of diamonds pairs the 5 for bottom pair (fives) with an ace kicker, and the lone diamond on board means no flush. Against the BB's capped range this is a weak made hand that beats bluffs but loses to every higher pair, so an overbet turns a hand with real showdown value into a bluff that no worse pair will call. Bottom pair should check to win the bluffs it already beats; overbetting only gets called by better.
Key idea
Bottom pair is a bluff‑catcher, not an overbet: it already beats the opponent's air, so betting big only folds out what you beat and gets called by what beats you.
Common mistake
Converting a made hand with showdown value (bottom pair) into a bluff by overbetting, when a check captures the bluffs it already beats.
