Are you sure MP3 didn't say that he had too many chips to push? Or maybe that's what he MEANT to say? It sounds like you're in good shape against him, and if UTG is playing too loose, you're probably in good shape against him. After all, wouldn't he want to get all-in PF against MP3 if he had TT+? I think you should push here, MP3 calls with whatever, and if UTG calls he will be in trouble with something stupid like AQ.
