QQ with K on board against a tricky villian

[DP388]

This was a 20/180. Villian seemed to be on the borderline between noob and smart player. He didn't seem to overvalue or call raises with dominated hands like QJ, etc. but who knows if I just didn't see those get shown down. Villian was also tricky in that he would sometimes slow play/trap.

Villian had made the following previous plays:

1. During the first orbit, he re-raised utg +1 with 52os. Ended up flopping a straight in a 3 way pot and got an overpair to donate his stack. Based on how he played after this, I think he was just making a maniac play early for image.

2. At 15/30 he called a raise from CO on the button with 33, I called with 88 in the BB. K high flop and it checks around on flop. Turn is a rag and he floats a c-bet from CO. I suspect he's floating and I call as well. River checks around and I win the pot.

3. At 25/50, 4 limpers and he makes it 150 with AA on the button, gets 3 callers and he checks behind on a K high flop and stacks someone on the turn.

So here's the hand:

Hero?

I sometimes will check here in a 3-way pot, but felt that cut off was weak so I played as if I was heads up with villian. Standard?

<font color="#CC3333">Hero bets t300</font>, UTG+1 calls t300, CO folds.

Hmmm...I'm not sure what to make of his call here on this board. He could easily be floating with 55-TT, has a set (33,44), KJ, KQ or maybe even AK.

Hero?

With my stack, can I effectively bet here? Do I want a call with a weaker pair? Can I get a marginal King to fold? Do I risk he's calling down with a king or trapping with AK or a set? 99 also fits his floating range.
