Axs in 6max preflop

[pottie]

Im looking for a general guide to playing these hands preflop.

Any comments on the following appreciated;

UTG and MP (first in) : A2s - A7s fold, A8s ??, A9s - AKs raise
CO and Button (first in): A5s - AKs raise
CO and Button (after a raise): Call AQs sometimes, reraise AKs
CO and Button (after 2 limpers): Limp A2 - A9s, raise A10s+
