KK - fold this?

[2planka]

Apologies, don't have the HH on this machine.

PP 5/10. Villain is around 65/5. I have 700+ hands on him. My notes on him are: "calls down TPNK, pays off. ~CS. unbluffable."

I had been at the table for about an hour, pushing it from the button quite a bit, and rarely meeting resistance. He's probably looking for a pick off, but I think this guy would wait for a real hand to snap me off.

Way ahead/way behind, or am I seeing monsters?
