[NL10] Overpair on flop faced with 2 raises

[MastermindT]

UTG: only 11 hands
SB: 43/4/1.3
BB: 19/2/3.0

I usually raise this preflop. However I was "mixing it up" when the following happend. What would you do?

Don't mix it up. Seriously re-raise pf. As played probably just shove.

UTG as a small stack probably shoves any flop, so you can disregard him... with BB donking and SB still to act, you probably need to shove and try to isolate UTG...

Anyways, with pocket aces, you want all the money in preflop.
