2-4NL - When do I take a stand?

[pologuy64]

The villian in the hand has shown that he doesnt mind 3-betting me preflop. We got it all in preflop once were he 3 bet me with JJ and i pushed KK and won the hand. With that being said, I still think he is 3-betting me more then he shoudl. Should I be folding, calling, or raising?
