QQ floats on the Turn -- sinking on the River?

Villain is rockish, but not a confident read. He's like 5/5/.67 or something like that... only ~30 hands and I didnt' stay at the table long enough to get a real read on him.

SB checks, Hero...

Is there any reasonable K hand that villain could have besides AK? I think we can basically discount KQ or KJs, AJ is possible and AQ is possible, however unlikely... trying to think what non K hand is 3 betting PF, c/r'ing the Turn. I guess ATs is a possible holding as well...

So, reasonable holdings that I can think of - AQ, AJ, ATs, lastly AK. Any others? What is your action - value bet? Check behind? If we bet, we have to call a raise IMHO and I don't think we're going to like it.
