a) lets give BB what I assume to be a wider r\gii range:
T9+,9+ : (Qdd+) :8J+,T+ : (JQ!RR,Jdd+),Kd
K,Q,J) : d,8JQ+ : (dd,9,T)
then b\stack off is +$16.5
b) now vs tigher range:
22+,9T+ : (78+,dd),JT8+ : (Q,dd,T,9),Kdd : (K,QJ,T2+),Qdd : (J8+,T2+)
still massive +EV shove (+$14)
c) vs super nitty x/r
99+,9T+ : (QJ+,Qdd+),QJK+ : (T,Qdd+)
= -$4.04
*72% of x\r range here is 99+
as was said before, I don't think you can call here with an intention of folding any turns.
So, I guess it comes down to how you identify his x\r range and play accordingly.
