Middle set in big-ish pot out of position

Second hand at the table for both villains, so no reads.

Preflop: Hero is BB with 4/images/graemlins/club.gif, 4/images/graemlins/heart.gif.
UTG calls $0.10, <font color="#CC3333">MP raises to $0.4</font>, Button calls $0.40, SB calls $0.35, Hero calls $0.30, UTG calls $0.30.

SB checks, <font color="#CC3333">Hero bets $1.5</font>, <font color="#CC3333">UTG raises to $5.2</font>, MP calls $5.20, Button folds, SB folds, Hero ...

At this point there is a lot of money in the pot, and I have middle set. However, UTG's raise really set off alarms in my head. Is this just MUBS?

Would UTG limp with pocket 10s? I would stick the rest in, you have the 2nd nuts at the moment, and it's inconceivable that he has 10s as opposed to all the other combinations of hands that he could have. Shove it in and pray that you hold /images/graemlins/smile.gif

Easy push. How would you ever consider folding this at 10NL?? The guy could have T8 here. I wouldn't fold this at any limit.

I wouldn't be worried that much. The only hand that beats You at the moment is TT. It's by far more likely at these stakes that he has TPTK, a flush draw or a flush and a straight draw. This is a fantastic situation to reraise all-in.

Cool, I figured it was MUBS. I have a bad habit of sticking with a hand when it's clear that I'm beat, but I think this is not one of those situations.
