<font color="red">BB bets 300</font>, UTG calls 300, UTG+1 folds, <font color="red">Hero raises to 1,320</font>, <font color="red">BB raises to 9,130 and is All-In</font>, UTG calls 6,275 and is All-In, Hero ???

I'm 100% sure BB has AA. WTF does utg have? I'm still confused. Should this be insta-call?
