Good or bad call? (5CD)

[Moneyline]

Unless the SB is a tight raiser I think the call (EDIT: I'm referring to the call before the draw) is fine. I think drawing 3 is the right move too. The thing I don't agree with is the call after the draw. For your hand to be best the button must be bluffing (probably on a busted draw), and the SB must be either a total calling station or trying to pick of a bluff with only 1 pair. Without reads I think there's no way overcalling with a pair of kings has a positive expectation. It's too likely IMO that either the button made his hand or the SB made something like 2 pair and didn't want to value bet into a draw.

Just my opinion...
