[sy_or_bust]

There is no reason to limp in with this hand behind one limper. It's the bubble and you have a deceptively weak hand, this is an awful time to play. AJ99 should almost never be played, period.

On the flop, you're committed for all your stack. You don't have enough chips to consider folding bottom set on a high flop when it's essentially heads-up. You're probably against an ace-high flush draw or some sort of straight/flush draw, but that is fine.
