Two 10/20 hands

[Bill Ivey]

Villain is a complete unknown to me, I have never seen him on the site and he just sat about 20 hands ago. He seems like a weak player.

Should I raise the turn?
Is the river over bet bad? I think he will call with KQ, and I think I am ahead about 80% of the time here.
