Best play: Bet 40% pot
Why
Turn (Q 8 4 2, one card to come). Hero holds K-club/5-club: with Q-club on board that is a king-high club flush draw plus a backdoor and two overcards-ish equity, against the SB's capped, mostly-give-up checked range. A small 40% bet is the merged/semi-bluff size that denies equity, charges floats, and keeps villain's worse Qx and air in while leaving room to barrel or check the river. Reserving the overbet for the genuine nutted turn hands and pure blocker bluffs keeps the small size for this medium-equity holding.
Key idea
On the turn, a draw with showdown-able overcards prefers a small merged bet: it denies equity and value-charges worse without bloating the pot the way an overbet would when you are not yet nutted.
Common mistake
Overbetting a bare king-high flush draw as if it were polarized value; with no made hand yet the small size realizes equity better and avoids getting blown off the draw.
