AA preflop

[nietzreznor]

Pokerstars 1/2 full ring

I am SB with AA and around $200. Been at the table for an orbit, haven't played a hand yet. No real reads on anyone else either.

Folds around to CO ($200, posted BB) who raises to $9, Button reraises to $28, I...?


Call or raise (and if so, how much)? Never sure what to do in spots like this in full ring games...
