That's a HUGE checkraise from villian. He's short stacked so he could be up to no good here. 4 hands beat you right now: 3-5, 22, 44, and 66. All the pp's are pretty good possibilities. However, villian may think his pp's 77-KK are good and you are seeing those at least an equal amount of the time. He also may be gambling with a flush draw or some such other garbage, J6 seems to be a favorite at this level. I don't think I can fold AA here to the checkraise, or be doing anything but trying to get BB's entire $18 stack in the middle.

EDIT: If he is larger stacked, than you should think about playing it differently.

What was the pre-flop action?

[ajmargarine]

I was assuming it was Hero raises to $1 and BB calls, all else fold. That's the best I could figger.
