So, I think this one is a clear fold.

Key information here is that the villain is tight/passive

I don't see the tight/passive player raising on the turn, without at least the K or pocket 22. Because the player is tight, the only thing we beat is KJ or maybe K 10 (but then, that's not what I would call tight). I really think we are up against KQ or pocket 22 here. He is obviously not pushing all in on the river without at least 3 kings, so at best we are hoping for a split AK.

But he's got a boat. Fold.
