Since reading the original post I have implemented this play with huge results. The nitish players scream I've got A's or K's pre-flop when they raise, unfortunatley (for them) they are so stingy that the raise is not more than 3 or 4x BB so call in position. If the flop is dead for the nit then he checks, dead for me I check and get to see the turn for free, if I hit I make a small bet, he calls. This play has worked best on the turn or river when the hand has been checked through and I make my set then. A large bet like 20XBB is getting a call and I take down the pot.
