You are ahead 99% of the time, his failure to re-raise you pre flop diminishes the possibility of him having kings. He would more than likely raised considering he has a raise and 2 cold callers, who could be holding weak aces e.g. AJ, AQo. Unless anything makes you believe this player is so sophisticated as to 'slow play' kings hoping to flop set, you must call.
