I think UTG should C-R the flop with a King and C-R the turn with an ace. So I assume he has an ace.

What about hero raising the river in case UTG hassomething like a lower PP that he is bluff betting with? or even 99 (though he would have capped that one PF) He might call the raise sometimes with nothing b/c of the KK88A board.
