overplayed or just right?

I see nothing wrong with the flop and turn play. Without knowing what he has it's .5BB better than putting him into calldown mode by 3-betting the flop, something that may or may not happen.

However after he donks the river, I don't think a raise is worth it here, he's going to have some random 2-pair often enough that this won't be profitable. This is just a gut feeling though, I have no math to back it up.
