Tnx for your reply.

My plan on the flop was to c/c against the donkey and to c/f against the guy I respect.

The combination of the facts that he should know that I probably don't have a K here given my flop check and his PSB on the river lead me to the same conclusion as yours, either a set or air.

I slightly discounted sets, because I was quite sure that he'd bet those at the flop. His big riverbet also didn't make sense with a set, since I don't rep a strong hand at all.
