Wow, you played horriblely. I'll never understand why players sometimes go all in to win a small pot. When you had AA, stacks were probably 1500 and blinds 15/30 if you were playing on Full Tilt. Why in the heck would you go all in to win a tiny pot with the nuts preflop? You should raise to like 5 times the BB, not all in. The next hand when you had A9, you were supposed to lose chips there, but not your entire stack. If you have the best hand, the other players will fold to a pot sized or 3/4 pot sized bet just the same as they would to an all in bet, there's no reason to bet more than the pot. A smaller bet will accomplish the same thing. No one is going to risk all their chips to call your all in with a marginal hand, even if they think you might be bluffing
, they're only going to call if they have you beat. You should have bet the pot with A9 on the flop, AK would probably raise, then you could call. Then check call the turn. Then check call the river, or check and he might check behind you. You'd still lose chips but at least not your entire stack.
