There's no absolute best way to play AA... no matter what anyone says. You have to take in a ton of factors when you play any hand. I think the most important of which is who you are playing against. Online this is usually limited information, but if you are paying close enough attention you should have a good clue as to whether you will get callers or not. This also has to do with position and timing during a tourney(if during a tourney). There is nothing like the rush you get when you see those rocks staring back at you is there? hahaha
