I would have folded pre-flop because I think K-3 often wins a small pot or loses a big one. And sometimes a limper 3-bets, as happens here.

I couldn't fold here with top pair after they all checked. So that leaves call or raise and I think I'd raise in case somebody behind picked up a flush or other draw. I think about folding if it gets 3-bet.

On the river, I call a bet and bet if checked to.
