Live $2/5 game

I think UTG+1 should have called here is my logic:

My read:
Button: Ace/Face, PP, K/Face suited
BB: Pretty confident AK, QQ through 22. Most likely PP. Outside chance at Kings, almost no chance he has Aces (he would have smooth called). If I had to bet probably middle pair.

UTG is playing almost 2/3 of the pot against the BB, who I am pretty sure he is in a coin flip against minus the outs of mine the button has. The BB puts the weak button on a big Ace, and wants to isolate him, and he is willing to gamble that the tight UTG player will laydown most hands, some of which are beating the BB. (From BB perespective I would guess he puts him on AA-10-10, AK or AQ,and he thinks he will laydown QQ-1010, AK, and AQ).
UTG is beating the Buttons range of hands.
