Best play: Bet 40% pot
Why
Turn spot: board Q♣ 8♦ 4♠ 2♠, checked to the CO. The BB is capped (no sets/two-pair raise here), so hero attacks IP. Hero holds K♣5♣ = king-high with one club on board (Q♣), so just a backdoor and two live overcard outs, no made pair. A 40% merged bet pressures the BB's worse king-highs and floats while keeping the pot controlled with a hand that does not want to play a big pot.
Key idea
On the turn against a capped range, a small merged bet can extract from a wide band of worse holdings while controlling the pot with a marginal hand. Sizing communicates intent: thin pressure, not polarization.
Common mistake
Misreading K♣5♣ as a flush or flush draw: there is only one club (Q♣) on board, so hero has neither. Overbetting king-high here as if polarized just bloats the pot with no made hand.
