Thought process was that the Villain here is a decent reg, reasonably aggressive, and although he could be wide preflop, he seems to play pretty well postflop. Because of this, I felt like flop and turn, I didn't want to push the pace when I pretty much have the board locked down; I wanted to give him the opportunity to bluff. On river, I remember saying to myself that I felt like the only hand that makes sense was KK with K of clubs (of course, he could have easily had KcJc, JcTc, etc.) but that didn't enter my brain at that moment.

He had KK with K of clubs to take the pot. Even after thinking about this after the fact, I don't really think I would change anything. But I'm open to other thoughts/interpretations.
