call on the river...AKo is most likely hand for anyone to raise UTG with--perhaps 50% of the time?...could be many other hands though (AA-JJ), so if you folded it would be no crime imho..

Now for some actual discussion about the hand.

Villain is rarely betting AK on the river here. Why would he bet it? He already has the nut no pair hand so what does he think you will call with? I doubt he's gonna try to makke you fold a better hand here as the river didn't change much of anything. Sure the flushdraw didn't get there but he already has a busted draw beaten. If I had AKo and got to the river like that, I'd check and take my free showdown and hope you had AJ.

A8o or some other no pair is much more likley for villain to hold than AK once he bets the river only b/c the weaker his kicker, the more hands he can fold out that would have been better than his if he had simply checked behind.
