KK vs AA on Pokerstars $50 NL

Hi I've been reading through these boards from time to time and finally decided to register myself. I usually play SNG's on PS but am trying to learn limit hold'em too. I usually play small stakes limit to clear bonuses on Party and Empire and sometimes $25 and $50 NL.

This is my first post.
