big blind, baby trips, bloated pot (party 5/10)

That sucks - The river is a fold. You're going to pay 4 BB with the basement of a fullhouse?

I suspect UTG did a delayed-raise with his 4-K or 4-A. Possibly 22. I can be 80-90% sure button has a J and is overplaying the turn.

With that turn action and insufficient odds (you know it will be capped), I would argue for folding the turn instead of investing 3 BB there and 4 more on the river. I know it seems weak but the situation looks very costly. If you fold a winner, move on and make a note.
