This is a hand from the Aria nightly tournament, about halfway through.

V1 (~5400) No foldem fish. Ran up a huge stack hitting his garbage hands like J6s, 63s, etc and now probability catching up with him.

V2 (~45K) Tourist. Relatively new to the table, only a few orbits of data and no unusual hands

Hero (~24K) Have been a little up and down lately. Probably more likely to be percieved as aggressive than nitty. Recently rebounded from about $15K without a showdown.

Blinds 300/600/50.  V1 limps UTG +2. V2 raises 2500 from the cutoff. Folds to hero in the SB. I have AQo It seems very likely that if I flat V1 will shove or at least call. I think the probability he folds is under 5%.  If i 3-bet he is less likely to continue without a premium hand.

Obviously I don't mind getting it in against V1's stack and range, but I'm unclear on what to do vs V2.

What is the best option here- flat or 3bet?

If we 3-bet, is this a fold if V3 shoves?

If we flat, V1 jams and V2 just calls, is it better to take the pot odds to see the flop or jam hoping to isolate?
