So I'm really trying to break down my play post flop and work on each piece. I have what I think is a good grasp of post flop play but then when it gets to the turn and river I still struggle.

Here's a typical scenario: Raise preflop with AKo UTG and flop air out of position. I c-bet 3/4 to pot sized and villain calls. Turn brings nothing. How often do you double barrel on the turn? Or is it better to check and let villain take control?

Now, let's reverse that - I have position on villain and he checks, I c-bet and he just calls. He checks again. Do you take the free card or try to rep the strong hand and take it down there? And if so, what size bet - I'm assuming PSB.
