What hands can you beat that give that type of action preflop with the coordinated nature of the board by 4th St? You have UTG capping and BOTH MP1 and Button calling 2 more preflop. By the turn you're more than likely looking at least 2 pair, if not a set or possibly a straight.

I don't think you can bet into this type of board on the turn. Check/Call it down.
