Whenever I see this hand, I cringe. Probability wise, it's a great hand. Not many will beat it. But I can't tell you how many times I've played AQ, only to see a King in the flop, and no help for me.
Worst is when you end up playing against AK with it. You'll have better luck eating a brick than winning a pot with this hand. It's cursed I tell you CURSED!
