Do I need to bet to win this pot?

[TripleH68]

Party Poker 2/4 Hold'em (10 handed) converter

BB is weak. 13/2/0.33. WTSD=14.
UTG Villain is 65/6/0.75. WTSD=44%. These stats only through 50 hands.
Villain and I have tangled several times and he has gotten the better of me.
I think his flop bet is suspect.
At this point I don't think he thinks I am making this play without a hand.

What do you think on every street?
Is the preflop play terrible?
