I remember reading a post by spoonitnow saying that AA is 85% favorate to win if we get it once.I think this is assuming we're headsup.The math for twice or more is .85*.85 giving us a 72% chance to win both of them.Spoon took this farther to .85*.85*.85*.85*.85 giving us about a 42% chance to win all five.Take this formula over a lifetime career and AA gets sucked out on alot more then you think.

Variance is a bitch.

Hopefully some more experianced players will chime in on this one.
