One thing I've noticed about pocket aces or kings is that whenever someone loses with them, just about everyone weighs in on how they were misplayed. Sometimes they are misplayed, but as the JJJ 10 10 vs. 10 10 10 AA full house story above reveals, quite often they are played perfectly but unluckily.
Even with perfect play, you will lose hands in Hold 'em. Everyone seems to know that, but they often seem to forget it. Decisions should be judged based on the bets, odds, pot and the circumstances before additional cards are drawn.
