Villain is 27/17 over about 40 hands. I've got a note on him from a previous session that says he limped K6o UTG which makes me think he's pretty donkish even if nothing else about his play stood out. Everything went ok I'm just wondering if I'm taking the right line here.

My basic read is that he could have a heap of crap that I beat so I'm never really folding on any street, even if an ace or a clubs hits. If he's being tricky with AA-QQ or has hit the 7 then he's going to stack me.

So how is my play? I just called on the flop with the hope of sucking out another bluff but I'm not sure if I'm giving my hand reasonable protection against a possible flush or overcards. What about the turn? Should I have checked to induce a river bluff or sized my bet differently?
