did I induce bluffs or miss bets?

Standard question, just thought I'd try to get some thoughts on this specific scenario.

8-handed 15/30. Third guy raises first in. I've never seen him, but in the first few rounds, he's made the impression of being reasonable, if a little passive. I 3-bet in the CO with the minor suit AA, and it's heads up.

Flop is 9h 7h 2d. He bets and I call
Turn is the 9d. He bets and I call.
River is the 3d. He bets, I raise.

He showed me his hand, so I know the results, but I won't tell you what he did on the river.
