Too many overcards? Too many villains?

[Bona]

I am posting this not because it was a big deal hand but because I struggle with playing overcards and need to improve at it. I felt it was mandatory to bet the flop since if it didn't hit the villains they might abandon ship. If raised I would have folded. Was I prudent here or weak tight not betting the turn. How about the river? Did I set myself up for it by not betting the turn? Or is that just poker?

I also struggle when I am holding the overcards to the board knowing when to bet them and when not to. I usually push the early rounds and fold on the turn when I have 2 overcards to the board.Sometimes I will continue, HU, If I am holding AK or AQ and the board is not coordinated. Any advice is welcome and appreciated.
