Certainly dump it in limit hold'em after the flop, unless you are last to bet and no one else does. You might try to bluff it on the flop in NL hold'em, but not in limit hold'em. In NL hold'em you play your opponents. In Limit hold'em, you play your cards. If there are no As or Ks on the flop, you fold, because the odds are not in your favor if any of your opponents are paired or higher. In this case, Cloutier is correct.
