This is a board where I would never fold a set. If there was anytime to fold a set, it would be when you flop a set of eights and the flop is 789 of spades. This is a dream situation for Player C. You have to feel that the players are trying to protect their big pairs. If I had flopped a hand that beat a set of twos, then I would not be betting so hard. I would trap my opponents. Why would I try to drive out a hand like AK, when I could get them to put another bet in on the turn. Also, if you never folded a set on the flop, then you would still come out way ahead in the long run. Fold
