I usually cbet this flop heads up and oop. Here I decide that I can get more value if nobody hit the ace by waiting until the turn.

SB checks, Hero checks.

Thought about whether to bet here for a bit. Now I think I should have bet about 1/3 pot, villian does play pretty agressively after the flop so I think I well ahead of her calling range. Haven't seen her get tricky so slowplay and cr bluff seem unlikely.
Final Pot: $1.45

If villain is as fishy as you say I might throw in a 1/2 PSB on the river. He would have bet by now if he had the ace, and I could see him calling this down with a middle pair.

If you think they will call with a 7 or 9, valuebet the river. Half pot should to the trick.
