How to play this?

Villain is a TAG.

I'm unsure about the flop raise. Another line would be to call until the end; that might cost me 1SB extra but I would get an extra chance to make trips on the river.

Same for the turn; I bet because I figured he would probably fold if he wouldn't hold a 9. But then checking would only give him 6 outs at most for free, while on the other hand if he would have the 9, it would give 2 free outs to me.

Any thoughts?
