Big Blind Calling Range vs Button Shove (6-Max & 9-Max)

At 10bb (6-Max & 9-Max), the Button shoves 33% of hands and the Big Blind calls the shove with 23%. At 20bb the call narrows to 11%. The Big Blind is last to act, so nobody can overcall: the only question is whether the hand beats enough of the Button's shoving range to pay the price, with the big blind already posted.

Effective stack in big blinds before posting blinds, chip-EV, no antes, everyone else folded, solved from 1 to 25bb. A number N means the hand is a pure call (at least 95% of the time) at every stack from 1bb to N; “—” means not even at 1bb. The 6-max and 9-max ranges are identical for this pair. Methodology.
