PS 50NL, Protect Hand, or Pot Control?

[markum9]

This type of hand comes up from time to time, where i don't know if i should be looking for a cheap showdown, or trying to protect my hand against a lone heart.

I just sat down, but in the first 15 hands i've already seen the villain call bets with a bad hand. (ie, AJ of hearts on a KT8 board, only one heart on board).

How's my line? Would it change if the villain was deeper?
