zoom KK on a dangerous board

It looks fine. River is close between folding and calling. Vs passive villain this would be a fold and vs aggro it would be a call but we can't know which villain is yet. I don't think calling is a big mistake.

The main question is this: is he betting his Overpairs that we beat?

I think there is a chance that he is. But he could also have a flush.

Flush, trips and sets are betting here.

Well if you think villain has only better hands in his range this should be a clear fold.

We can call from time to time.

I call here vs. a fish.

Your sizing on preflop could be bigger. I have two reason for that.
The first is that you both have more than 100 bb stacks.
The second is that villain looks like a weak player.

Thanks for the input, guys!

You are welcome.
Flush was one of the options we gave you.

But you all failed to mention that he might bluff. This is the thing to consider, not the remote possibility that he value bets TT and expects to get called, and not the hardly surprising bets with nut flushes and the like. He should be bluffing something like 35%+ here, and probably is since you ask him (by checking) to do so. I'd call from time to time (meaning AA is a call, QQ is a fold and KK is a don't know).

I am glad that you agree with me on calling from time to time. I think this includes the bluff part you write about.
