So I'm guessing he had K-5-x-x and berated you in the chat after the hand?

This depends on what the dynamics like heads-up (i.e. were you playing tight oop?, was he playing the button aggressively?). If you're playing tight oop, he only plays back at you with K-5-x-x (or 5-5-x-x...same hand) since if he just had a King, he'd probably take a cheap turn in position.

The flop is so dry that if you do face a lot of action on this flop, you're probably behind (or up against a donkey in which case give me his screen name please!). Bet calling on flop means that if he is indeed using position, you can let him fire again on turn. If you 3-bet on flop, he would simply give up a bluff.
