I was a little confused on this hand as to what Villain had. His check on the turn made me think like he wasn't so sure if he was ahead anymore or he may have been bluffing the flop and decided to give up completely. My first instinct was that he had AQ. I thought he could be making this play with the Kd but how likely is it that he called that raise with a K? He could have had KK & been going for a limp re-raise and decided to cold call since it was already heads up but that is kind of unlikely. KQ usually fold here. I didn't think he would risk giving a free card here with a set or a small flush. Any help?
Sorry I don't have the exact hand history so it's gonna be a little sloppy.
