Sometimes I like to check-raise the turn in these situations so I can build the pot more than I would've likely been able to by leading out. This is especially effective against passive players who will hold onto any ace the whole way no matter how big of a hand I represent.

You might've slowed down a little bit on the river. When he calls you on the flop, he's indicating he has some sort of a made hand, since I wouldn't expect him to be chasing an inside straight draw if he is a tight player. His likely holdings at that point are probably A-J, A-K, A-Q (less likely) Q-Q (less likely) or 9-9 (less likely, but more likely than Q-Q) since he called a preflop raise. If he's a decent player, Q-Q and 9-9 are the only hands consistent with the river raise after calling every street, and so you should probably just call. This seems like a pretty typical line that fish and average players like to use with sets.
