Villain has a WTSD of 25 and a WSD of 29 and I also had notes on him.
Barreled three times in a 3 bet pot with no hand at all (on turn and river there where scare cards though).
So I know that he can be very aggressive in the pot with no hand and has a loosing.

On the turn I decide to make a small bet at the pot which seems like I am playing to steel the pot although actually I have a good hand top pair and lots of redraws. Villain with a bad agro reputation decided to raise my smallish bet quite large (pot sized). I don't think he has an A as he did not bet the flop so might first reaction is say what and I make the call. His big pet on the turn makes me believe that his range is polarized either he trapped me with AA or he has nothing.

River is a blank and now he makes an polarizing allin bet. As I don't think he would make a large raise with AK and prob also not with two pair he has not a lot of NUT combos on this board but can have many bluffs so I make the call.

What do you guys make of this line?

thank god for HUD stats and notes :)
