I am not sure really sure why we want to charge ourselves for draws. Not many live players fold pairs. It is also possible that we are drawing dead. In other words, I am leaning towards a fold more than a CR or a call just because the way the flop erupted. It is very possible that the bettor has something like AK with maybe an A of clubs and the initial caller has now a fd that he wants to get a free card on the turn.
