Turn card is ugly, but villian checks, and I have no stats on villian. I'm not ready to give up yet but is a blocking bet in order here? I bet $5 but that might be a bit much.
I want villian to call with a Ten or worse Queen and save money vs a King. I can't see checking to induce a bluff. Villian should have at least a pair after turned king.
