Don't know how to go with these boards. Seems like both ranges don't hit this board really well but I know from experience a one and done approach doesn't achieve much on this board structure.

So I'm either double barreling or not barreling at all. Which combos you bluff on this board?

I would see me bet AQ here sometimes, don't think it's bad, but don't wanna be overbluffing Turn.
Ok as played we check, he bets, which is kinda expected, think I need a check/raise range on this board...
oh well so I fold but with AQ+backdoor I would call.

Or would you have check/called flop with this holding? What's the best line?
