Best play: Overbet 120% pot
Why
Turn (Q‑8‑4‑2). Hero has K-high with K♣5♣ — no pair, just a backdoor club blocker; pure air on this board. The BB checked twice into the IP BTN, so their range is capped at one-pair-or-worse (no slowplayed sets after a passive line). The overbet is a polarized semi-bluff: it leverages hero's nut advantage IP, denies the capped range its equity, and folds out Qx that cannot withstand 120-percent pressure. The K-high has no showdown value to protect, so betting big rather than checking is correct.
Key idea
Against a capped, twice-checked BB range, overbet your no-showdown high cards in position to deny equity and apply max polarized pressure.
Common mistake
Checking back the K-high 'to keep the pot small' — that surrenders the whole capped pot when a big bet would fold out the Qx that beats you.
