Overpair multiway...

I don't see what the question is, but as a general rule, if one player goes berserk, there is a chance that he is fooling around. If two players go nuts on the flop, there is a much much smaller chance (not half the chance, smaller) that both of them are kidding. With three players going bonkers, chances are practically zero that you are good, very much so if this happens on the turn.

I'm not saying anything here that you don't know already, I'll try to explain what I mean.
What I am trying to say is that multiway, people bluff much less, at least they should. As an adequate approximation you can set their bluffing frequency to zero if there are three or more of them, especially on the turn when semi-bluffing isn't profitable anymore, even multiway, probably already on the flop since it is so unlikely that all are drawing on a board like that given the preflop action.

I think you played it perfectly.

Sorry, my question wasn't explicit. I was a bit pissed off the day I posted the hand. The BB and UTG players were regs, MP3 is the weak player.

What I would to know is the general line you would choose if you were in UTG's shoes (with your entire range). I don't understand the raise on the flop with such a low PP. I guess his coldcall after the cap flop make sense because of the pot odds+implied, but what's the point in raising the first time here?

Concerning my play, I'm not 100% sure this is a 3bet on the flop because I can hardly handle a 7, and I need to be really strong to give action and I think I should still coldcall a lot on that flop (so I should have some strong hand in my coldcalling range too). On the turn, facing a 3bet cold, I can't continue, but here again, I'm still seeing regs raising again with TT being UTG.
