UTG must have been OVERJOYED to see the all-ins on the river. I understand the feeler flop bet; SB, BB & Button all limp and he wants to clear out any potential draws to the straight or flush. It is a fairly scary board. A call from both the SB & Button indicate to him that he may be beat by a Q or just possibly a K. He controls the pot on the turn, checking it down. Then the river wallop hits him hard. For $3.07, he has to call.
