2/4 FR, Betting AKo UI in 3players, Playing TPBK passiv glad to reads

[kamel]

I'd be glad to hear your valueable advice in 2 hands, played on 2/4 FR on stars.

1) None of these villains were known to me, for at least they are no 2/4 regulars.

Here, my main interest is the betting-out on the flop with UI AK facing a family pot OOP. When I played, I thought, that not so many hands will connect (hard) with this flop, so I even still might have the best hand or the best draw and I didn't want everybody to know, I have unimproved overcards.
When I stoved against a &gt;30% range villains might have (might be reasonable), I found I have a slighte equity disadvantage.
However, my main wondering is: Is there any point betting out unimproved AK on those dry flops?

2) Allthough not many hands, I noted that BU liked also to limp with good Ax and played them passive when faced with bets and especially raises (I've seen him calling down Top2)

Here I tried to find a line between potcontrol and valuebetting.
Given the 2 player types (aggressive MP, loose-passive BU), I decided that it might be worth to play that hand different from textbook. I first wanted to see who bets and then to decide how to react.
As the passive player bet on an Ace-Flop, I didn't want to blow the pot, so I only called and checked the turn.
River of course was betting for value.
Is this just fancy play or is there any point in making these plays?
