Why
River (J‑8‑5‑9‑2). Hero holds T‑8 of clubs, pairing the board eight for a pair of eights with a ten kicker — a weak made hand, not a straight (the board gives 8‑9‑T‑J but the seven or queen never arrived). This medium pair beats only bluffs and worse pairs; an overbet folds out everything worse and is only called by better. The correct line is to take a cheap showdown, so checking is best and the prescribed overbet is wrong.
Key idea
A pair that only beats bluffs is a bluff‑catcher, not a value bet. Polarized overbets are for the nuts or for air with blockers — never for a thin made hand that loses the moment it gets called.
Common mistake
Overvaluing a board-paired middle card. Pair of eights here is a showdown hand; betting big turns a guaranteed-some-equity check into a spot where you only get called when crushed.
