TPTK v unknown turn raise

[ElSapo]

I started today with energy and hope (and the plan to play tighter than ever and try and get back on track). After 450 hands at 15/8 I'm stuck 30 BB and pissed off. So maybe this hand is standard, and maybe it's not, I just don't know.

I raise UTG with AdKx, and get called in MP by an unknown. I have 2 hands on him. Flop is AcQd9d, I bet, he raises, I three-bet, he calls.

Turn is a 2s, I bet and he raises...

It's going to cost me two more bets to see a SD. Who goes there? Everyone?
