Best play: Bet 33% pot
Why
Q♥9♣4♦ is a moderately dynamic queen-high board where you, the CO preflop raiser in position, still hold a range and nut advantage over the BB. Your A♥5♥ is ace-high with no pair but with a backdoor heart flush draw (you hold A♥5♥ to the lone Q♥) and a backdoor wheel draw, giving you live overcard and runner-runner equity. A small 33% c‑bet is the default: it denies the BB's two-overcard and gutshot equity, applies pressure with your range advantage, and lets your backdoors barrel profitably on hearts and other improving turns.
Key idea
Small c‑bets with ace-high plus backdoors deny overcard equity cheaply while setting up profitable turn barrels.
Common mistake
Checking back surrenders fold equity and lets the BB's overcards and gutshots realize equity for free.
