UTG had a set of 4's. He was semi-loose/agg and I had no read on CO. UTG was on a bad losing streak and just berrated me for my play.

Turn three bet was stinky, especially since a guy cold-called two on the flop then all of the sudden woke up on the turn... it reeks of set. You got bit by a classic slow-play, in fact they are so classic that they are going out of style. Be careful not to be caught in one again.
