CO is 43/23 loose player while I didn't have stats on BB.

Flop was good for me since it shouldn't have hit anyone hard. Next time, I would go for a bigger sizing
I didn't want to face aggression on the turn so I checked back intending to call. Maybe I should have bet especially with my Ad.
The river was pretty bad for my range and good for BB's range but I didn't really think BB would x back with a low rundown or flush draw on the turn. Since I had the nut blocker, I decided to bet.

Any thoughts on how I played?
