NL100: TPDK on drawy board, allways seem to get to involved

[XST]

Villain is 44/20/4 over 30 hands. I have a lot of problems with these hands on draw heavy boards. I can fold the hand easily when the hand isn't very drawy but when it is I get paranoid and I seem to get involved in a pot which is way bigger than I wanted it be, sometimes stacking off really light. In this situation I am not sure if he is betting a draw and trying to give himself odds or actually has hand.
