AQs Turn semi bluff

1/2 game, $250 stacks. Hero puts out button straddle $5 (rare for me). One limp in EP, Villain limps CO, hero raises A♣Q♣ to $20. EP folds, V hesitates and calls (read: it's a marginal hand)

Have had 3 pots with this villain that went hu past flop. One was checked down, 1 he bet $50 in position on river I folded, other I bet $50 in position on river, he called, i won.

Flop ($43, hu) T♥9♣2♦
Check, bet $25, call.

Turn ($91) K♣
V checks, hero?
