Just fold. Despite your reads it's still an UTG raiser, button squeezing an UTG raiser and you're trying to rep a slowplayed KK+/AK which people never give credit for. I guess you could call but you have a reverse implied odds hand so you'd have to be careful. Surprised you think UTG is capable of calling with worse... even terrible players don't usually call preflop shoves for 80bb with A2-AT or KQ.

This play (bluff shoving over a squeezer) is better when you're the pfr'er and it's a more typical squeeze situation (co raise, btn flat, blind squeeze or btn raise, sb flat, bb squeeze).
