Hi, my oponent is pretty loose fish with stats 50/14 after 100 hands. The villain is such station postflop.

What strategy choose vs. a player like this? If Iam on BTN and blinds are not aggresive it is easy overlimp for me. But how to play in this situation? I can not exploit this player postflop. I hit monster not very often. What to do with this hand?
THANKS
