I think you can definitely make an argument for raising any street in the hand.

arguments for raising the flop have been made, but I don't think it is horrible to just call.

I think the turn is a definite raise since there are straight and flush draws possible and you can force the third player to pay to draw. Also it is pure value since you have the best hand the majority of the time.

as played on the river I really think you should raise since you will get a call most of the time, but a lot of the times that you would have gotten the overcall they might overcall two with a K anway.
