Best play: Bet 75% pot
Why
Q♥9♣4♦ is a more dynamic, connected board (Q‑9 with straight potential) where the BB defends a lot of pairs and draws, so betting must be polar. Your A♠7♠ is ace-high with no pair and no draw (no spade on the flop), but holding the A♠ blocks the BB's nutted ace-x and flush backups. Big-betting 75% turns this air-with-a-blocker into a pressure bluff that denies the BB's many overcard/gutshot equities and sets up barrels — small betting it would invite cheap floats with nothing to fold.
Key idea
On dynamic boards, bluff polar and big — pure air with a key blocker prefers the large size to deny equity.
Common mistake
Betting small with air on a connected board lets the BB float cheaply with all their overcards and gutshots, realizing equity you wanted to deny.
