I think I am ahead a lot against the bb, he could have Kx and also QJ. My main worries is set of 4's, possibly KT and maybe tens but that seems unlikely.
UTG cold calling is somewhat worrying but then again he is a big calling station judging by his stats.
What's the play?

Not really worried as much about utg as bb. I think with a big hand, utg doesn't just cold call the bb's min raise, but he puts in a big raise of his own. I see him with a KQ, JK hand (possibly QJ). The BB could have K 10 or a set, but imo he just as easily cold have KQ or KJ.

I think I shove here.
