The villain's line looks like an underpair that is hoping you have AK or AJ (99, 88, 77, maybe 44, even JJ rarely.) That King is a horrible card not only because some hands pulled ahead of you but also because, against a reasonable player, you lose all the value you had in a river bet. In other words, he's no longer beating anything against a typical preflop cap and he knows that. I think you get him to fire off a bet with a worse hand more often than he calls with a worse hand. Also, this early at a table against an unknown, I hesitate to use the bet/fold line and I'd like to show down a hand here. check/call is my line.
