Yeah, and don't call the short stack with AQo. I'm afraid the re-raiser got a good read on you. That call, w/o the shove that says "I just isolated him, this pot is MINE" is simply screaming one of two things:
a. You've got a monster, and really want everybody to play, and it's a trap for me, or
b. You're sitting on a marginal hand, but have been very careful, and the fact is, you can get away from your hand, and not be hurt too much.

Very nice. After watching you for a minute, the raiser figured out which one it was. ON the nose. He didn't need an ace to make the raise, but if he found even one in his hand, well, it's that much less likely you've got two of them. Here comes the shove.
