Would a TAG really call an UTG raise with A3s out of position? I'm thinking 88-JJ, AQ-Ts, KQ-Js, AKo.

How does the SB see you and MP2? Is he making the call because he thinks you're LAG or LPP.

I put him on a draw or a smaller pair, so I would cap the flop and bump him on the turn, and call down if he 3-bets the turn.
