50nl 3-bet button qq vs steal, flop king high

[daven]

villain is 17-15 and i've 3-bet him twice in the last two orbits, he's folded so far. This time I seriously considered flatting, but nah...
should i fire a turn xecond barrel or think about pot control?
as played I debated the river a while...

I definetively don't c-bet here. This is more like a WB/WA situation. Let villain bluff on turn/river.
Your line looks like a scared AA, QQ/JJ or air. With your line I think you have to call here (because you have 3betted him twice in the last 2 orbits, so villain has to put you more on air here and at 50NL they are not good enough to c/c 88-JJ here).

I call because he either has nothing or like AK here. Or maybe quads. I would think he'd raise or bet with aces on the flop if he decided not to 4bet.

You either bet the flop and check the turn here or you check the flop.

And there's the point about lower pps betting into you... I wouldn't play them like this, but I'm not the person you're playing against

I would check behind on the flop. I think that would totally change the dynamic of the hand so its hard to say what I do after that. But as played, I just call the river. I think more often he has something like JJ, TT rather than a K (although he could easily have a weakish king obv).
