Not sure if this is a standard spot or just a slight mistake. Villain looks like a reg. I make the standard 3b but it's probably too small. I think flop and turn are standard valuebets, although they could be bigger. As played I think his river range is kinda strange. I think he makes it bigger with his big TT-AA pre, so I think his range pre is full of speculative hands, but I also think his sets and baby flushes will x/shove turn.
Maybe a spot to b/f river?
