Hi,
I did this analisys considering set over set and quands vs set in this thread:
http://forumserver.twoplustwo.com/showth...e=2#Post9343754
It comes down that for the call to be EV+, the small pp needs to be able to win more than 9.5 times the bet he is facing.
So in your case, small pp lead for $8, AA on button raises to 8+X, sb folds, bb folds.
Pot will be 8+1+2+8+X=19+X
And the reward is: 19+X+(200-X)=219+X
219+X=9.5*X
219=8.5X
X=219/8.5=$25.76
That is the break even point.
If you want to simplify the math, the reward is 219+X aproximated to 220, so the reaise that the small pp can call is around $22 ($22 is the raise, so he has to put $30 on the pot).
