I'm assuming his hand range is wide since he posted in early position and I'm thinking he thinks I have big cards or a pair preflop. After I raised the flop I'm thinking he's thinking I could have an overpair, but he also could be thinking I'm trying to push him off with just high cards.

He donks the turn. Is the combination of the strength of our hand, with his turn aggression reason enough to raise the turn? Or do you think his river donk means he can beat a top pair-like hand?
