It's happened to me a lot, late in a tourney and I'm in middle to late position and look down and see AQ. Someone will make a significant raise and I'll reraise - they will then put me all-in. They turn over KK and my head turns into a giant tootsie-pop. Or, they flip a small pair, have a small edge and I never catch a card.

Have I learned my lesson? I hope so, but after a long drought that AQ can look soooooo good. Kids, let this be a lesson to you...
