Taking a passive line with AK

[Rainclouds]

Villain is a decent 21/17/3, might be 2p2 but I don't know him. Or her.

There's actually a lot in this hand that you might not like. My line of thinking:

Preflop is usually a 3bet but CO was a fish which I wanted to keep in the hand.

Flop bet is standard.

Turn card kinda sucks since KQ got there, but I still beat mid pp's and split with AK. I c/c because I can't really bet for value except against maybe KJ, but I do believe I'm ahead of his range, while my check induces bluffs. Is this OK?

River: if I c/c turn, it makes no sense to c/f river (or does it?) so I c/c again. Should I c/c here?
