Party 25NL - TP2K slow played

[payoff wizard]

Villain is 17/11/3 over about 250 hands. I was very sure I was ahead on the flop when he checked to me, so, because the flop was so dry, I decided to let a card peel off for free to try and get more value. So WTF is he 3-bet shoving the turn with? I need help ranging here.
