I might be wrong, but he is getting 4.1:1 on the call (for the last $53.25), so I don't think THAT is so bad--isn't the FD about that to come in? UTGs initial overbet of the pot says he wants to win right there and that he doesn't want a call. Mathtematically, calling (or raising) the first overbet seems to be the mistake here. I can't think you stack him if you smooth call and hit. Not with the overbet saying he's vulnerable. So it comes down to push or fold and I think folding is better.
