what to do with AK here?

[mike l.]

i didnt play this hand. hero is a semifamous long time LA mid limit pro who plays pretty well. utg is a very good 2+2er. other players i dont know. 50-100 live game in LA.

hero is in mp w/ AKo. utg raises, donk calls, hero 3 bets, blinds call, utg and donk call. 5 for 3 bets.

flop is AhJh8s. all check to hero who bets, sb folds, bb calls, utg checkraises, donk calls two cold, hero 3 bets, blind folds, utg 4 bet/caps, donk calls, hero calls.

the turn is 3c. utg bets, donk calls.

here come the questions:

1. should hero raise, call, or fold and why?

2. if hero raises and utg 3 bets what should he do and why?

i think you guys will have fun with this one. lmd and i talked about this for quite awhile before he got bored and hung up on me when i started to get too hysterical.
