Stats over how many hands? I would avoid flatting hands OOP in 3B pots. This is a good spot to 4B bluff as you are UTG and having any kind of blockers def would help. Its highly unlikely to get 5B jammed bluffed from a UTG 4b so you can 4b/fold happily. I still wouldn't 4b/call 88/AT tho even if you were CO here.
