Villain is 83/33/1.5 over 81 hands. Obviously he's been pretty agressive. I've seen him call flop w/ NFD and stack on turn without hitting the draw with just A high.

Should I raise here? How much, and should I fold to a push?
Also I'm not always calling turn but I did hit the NFD along with 2 overs. Actually, maybe I should have raised turn??? I'm not really sure.
