AA - OOP and terrible turn card hits

[cs3]

<font color="blue"> this is a pretty common spot and should be simple, but im not sure what the best line is to take on the turn when everything reasonable hits

villain is a 19/9 ABC tagfish. pretty passive postflop, hasnt done anything stupid so far over ~100 hands
