Why
On K♠J♠7♥ the BTN raiser owns the top of the range (more Kx and overpairs) and hero is OOP and capped, but hero's Q♦J♦ flopped middle pair (the J) with a queen overcard and a backdoor diamond draw. That is a clear bluff‑catch / pair-and-draw rather than a fold. From out of position hero check-calls the c‑bet: middle pair has enough showdown value and equity to continue at a reasonable price, while check-raising would only fold out the worse hands and isolate against the Kx that beat him.
Key idea
OOP, middle pair with an overcard and backdoors is a bluff‑catch — call to keep worse bluffs in, don't raise into the value.
Common mistake
Folding middle pair too readily, or turning a fine bluff‑catcher into a raise that only gets called by better.
