I have a real hard time with these hands. I hate life as soon as he catches that Deuce, but I think you're ok here. I think it's reasonable for him to call the completion with a variety of 3-card lows but not so much with baby-2-2.

On 4th he almost has to bet regardless with what he has, particularly since you each caught a King. It puts a lot of pressure on you and the other Ace if you were both on low draws only. Had at least one of you caught a baby instead it might be a different story.

If I trust my read then calling 5th is ok but I think it's close.

6th is interesting once you catch a Deuce and he checks to you. I think you have to bet here, if for no other reason to get rid of Seat 6.

My inclination was to check behind on the River, not seeing any value to it. But now I think you should since your hand looks like a made low and he's pretty unlikly to have trip Deuces. My guess is he'll call with any made low and pay off with any weaker two pair.
