With that dangerous of a board, raising the flop big seems appropriate to me and then shutting your opponent out on the turn when the blank hits with another large bet. Based on the action, your opponent is only beating you with 2 hands KK and AQ. He would most likely expose his strength to a large preflop raise. Get reraised and you fold bottom two, only get called, jam the blank turn card. This board is way too wet to screw around when playing bottom 2 pair. It needs to be played strongly on every street, unless the scare card hits, then you shut down.
