Anyone like this line or should I just qoute MK now and say "You sir, are a noob"

Hero is BB with
![The King of Diamonds [Kd]](https://pofex.com/images/smilies/Kd.gif)
Villian is CO (He seemed weak tight but hadn't seen him show down any hands)
Preflop: All fold, Villian limps in CO, Button and SB fold, Hero checks.
Heads up.
Flop:
![The King of Hearts [Kh]](https://pofex.com/images/smilies/Kh.gif)
Hero leads, Villian calls
Turn:
![The Ace of Spades [As]](https://pofex.com/images/smilies/As.gif)
Hero checks, Villan bets, Hero raises, Villian calls
River:
![The Nine of Hearts [9h]](https://pofex.com/images/smilies/9h.gif)
Hero bets, Villian calls
On the turn I'm trying to rep 2 pair or a weak A.
Thoughts?
Given the turn play should I check/fold river or is it better to lead?
Thoughts?
