Preflop Question?

[Piiop]

Party Full, I post in the CO. 2 folds, Laggy McLag opens. I estimate he will openraise with anything he wants to play here cuz there are is a poster and two folds. His range here is premium hands, any pairs, any two broadway, any suited ace, maybe a spicy suited connector. Folded to loose-passive guy on my direct right who calls. The button is a certified Rock. The blinds are strangely unknown.

I have A9o and I do what?

(Also, while I was typing this post, I made a bad play. I am retarded.)
