Obviously hand equity isn't enough to determine everything we need to know. However, it seems that there are so many marginal situations where the decision comes down entirely to what the rake and blind structure are. I'm simply wondering:

A) If there isn't a formula/graph that shows how far ahead equity-wise you generally need to be in order defend if you make the assumption that both players are equally skilled. Basically how the % of rake changes the % of hands you need to defend with.

B) Also while this is basically the opposite of the 1st, what ranges worth attempting to steal based on how far off the player in the bb is off in his defense % (again taking into account the rake and blind structure).
