Don't listen to Tokem, he's an idiot. Any time you're around 5 BB or less in a tournament, your decision is all-in or fold, you still have some fold equity preflop, but zero after the flop, which means if you call you're gambling on hitting the flop HARD (top pair high kicker or better) because chances are your opponent will bet and you'll be in a bad spot.

The 99 vs AQo is questionable. The guy made a crappy call and lucked out on you, but with 10BB it's not necessary to make that gamble from early position - you're risking way too much for what will either be the blinds or a call from a hand that can beat you.
