Final Pot: 14.16 BB

CO is loose-passive so far (seen 16/32 flops, some with pretty ugly hands).

UTG is new, I'm not too concerned about him having me beat on the turn.

Is the turn 3-bet correct? At first the turn raise seemed like a 4, but if he's CCing with hands including fours, then something 87 is a possibility to. Thoughts?
