I disagree with everyone here and I like how you played it. Don't listen to people who say that you need to c-bet for information. Sure, if you bet at this flop, you will get some information, but you will also lose money. I also would check some of my aces at this flop, like A5s, A4s, because otherwise our checking range would be very weak. On the turn, facing a bet, you can't really fold kings here, because it is top of your checking range. You will fold your broadway cards, some smaller pocket pairs, if you fold kings here, that would be too much. As played, river is easy fold. You played it perfectly.
