Best play: Bet 33% pot
Why
Q♥9♣4♦ is a semi-dynamic queen-high board where the CO preflop raiser still holds the range advantage over the BB. Your A♠7♠ is ace-high with no pair, holding only a backdoor spade draw and the ace overcard. A small 33% c‑bet is ideal here: it pressures the BB's many missed hands cheaply, denies equity to overcards and backdoors, and keeps your bet small since you don't want to risk much with a hand that mostly wins by folding villain out.
Key idea
Ace-high with backdoors on a queen-high board is a textbook small c‑bet: cheap pressure plus equity denial with built-in overcard outs.
Common mistake
Checking back ace-high here surrenders fold equity against a wide range that folds far too often to a cheap bet.
