Best play: Bet 75% pot
Why
Q♥9♣4♦ is a moderately dynamic, connected broadway board that interacts with the BB's defending range, so betting big polarizes rather than range-bets. A♥5♥ is ace-high with no pair but carries a backdoor nut-heart flush draw (A♥ over the Q♥) plus the ace overcard and a wheel-ace blocker, making it a natural semi-bluff. The 75% bet is defensible: it applies maximum pressure on a texture that misses much of the BB's range, denies equity to two overcards and gutshots, and can barrel hearts and aces with the nut blocker.
Key idea
On dynamic broadway boards, bet big to polarize, using overcards plus a backdoor nut draw as your semi-bluff equity.
Common mistake
Treating A-high with only a backdoor draw as a check-only hand passes up the fold equity that makes the big bet profitable.
