This is a pretty easy fold. Even if you are ahead of spastic's range, the two other players going all-in after a large bet and a raise looks pretty strong IMO, especially UTG. I would range the smart guy as JT, 33, TT and Q9
in this spot; if he is as competent as you say he is he never has AJ or KJ in this spot. Then when UTG calls the all-in after a bet, a shove and a shove you know he has KK beat 99% of the time.
