If you call and let him see a flop it sounds like he will make less mistakes and you give him an opportunity to out draw you. Sticking to the aggressive play with this opponent would be my default.
I might be wrong here but I disagree given the stack sizes and the possibility of villain hitting an Ace on flop. Hero is over a 70% favorite pre flop to A9o. If hero was like 12 BB or less I'd say shove or fold of course.
So villain's reraise shows some strength, does she have AA, KK? Probably not because she would have donk shoved to your pre flop raise in this spot in a tourney so she probably has Ax Kx or something like 99-JJ. If you flat the re-raise and see a flop with no aces and no kings you have some room to maneuver. If hero is first to act on a safe board he can either put out a small feeler bet (maybe 1/3 pot and maybe find a fold if villain insta shoves ) or if he has villain read like a book then shove flop. If villain is first to act and checks hero can shove and take the pot down. If the flop brings a Q you're golden. I'm doubting this villain is floating overpairs or trying to do some fancy play here.
I think we're giving villain too much credit here that if she's 3 betting with A9 off suit then she's good enough to play the flop correctly, in fact if she misses the flop she's going to make mistakes.
I get that position here is critical and since hero is first to act it gives villain the power but it's likely villain was donk raising pre flop hoping to spike an Ace and take it down. And since hero doesn't have to shove/fold pre he can outplay villain on flop in most situations.
Cut stack sizes by a few more BB and yeah shove.
But I do see your point and it could go either way. Overall though I think here, especially given OPs comment that villain was complaining of OP blind stealing that a nice bet on flop would fold villain and avoid leaving the pot up to chance with that Ace coming. Of course with everything it depends. If you know villain is re-raising pre with junk like Ax or Kx you can shove and take it down pre. But if you're not certain you can see a cheaper flop and take it there.
