I could certainly see a 56 here, I think that probably bets the turn too. I could be wrong, but with two pair I would be suprised to see that here. though not floored by it
Certainly I cannot expect him to put me on AK specifically, but maybe more "strong A." I should say he has seen me take this line in the past with AK, and I would think he is aware that I would/could take that line on this flop. I think he would NEVER put me on only AK, but I think he would expect to see that here. Though it could also be JJ+, or certainly the exact hand I have.
But all that taken into account, my KQ is almost no different than AK is here. Since he is never (almost) taking this line with an A he either is bluffing with nothing or crushing me.
my eqity with AK here probably runs almost even with my KQ.
