Hello Gregor86,
Flop: Well, what's your plan here vs the fish? Do you plan to Check/Fold directly or Check/Call? If you plan to Check/Call then I rather prefer CBetting myself here.
As played
Turn: Kind of close spot, especially when the reg leads out here, I might even take pot control and skip the thin value. What's your plan if you get 3bet?

Also if you raise then why do you give him great odds for FD? Do you think he going to continue with a lot worse hands?
As played
River: Not much to add, no thin value even for us.
Best Regards.
