AA, not always a winner

[Zybomb]

That is very very very unlikely, unless of course you had multiple callers.

Keep in mind AA is roughly 80% against another pair -- this means 80% not 100%, so you will get cracked from time to time. 8 out of 10? There's something seriously wrong there.

There would need for there to be at least 5 callers each time to your aces (all with decent holdings) to have that happen (and suppose to happen)

What stakes are you playing at? Whats your table image? How did you play AA preflop? How do you play other nice but not monster hands preflop (AQs etc)
