Think this guy plays for stacks with AK on a Kxx board? If he would play it passive post-flop too then I think you have to raise it up on the flop for information and to protect against the 3rd guy. Intend to check behind on a laster street.

That being said, I think your line isn't too bad. Heads-up it would be perfect, it's just what to do about the other guy hanging around...
