Fold the flop. Pot's small and you're likely to be behind. Avoid trying to get clever in this situation, especially readless.

I think there's an argument for betting the river. Though I'm unsure whether villain will fold any better hands, or call often enough with a worse hand. I'm leaning toward bet/fold as villain's line strongly suggests he holds a K without a club, and I think he'll pay you off enough times with this. Plus there's a slight possibility you will fold a better hand.
