Call flop and push the turn to rep the king. I think most thinking players will fold without one if you take this line. Or you could minraise the flop and push the turn, folding to a 3-bet allin on the flop, as a lot of low-stakes SnGers will play trip ks this way and it will be hard for him to call without a king. Moreover, if he is trapping with a weak lead, I think he'll often push over your minraise on the flop. Or you could fold, but that's so damn boring.
