Big Blind calling range vs. UTG+1 shove - 8bb, 9-max
Big Blind calls 21% of hands here at 8bb effective (39 of 169 starting hands go in at full frequency). Facing an all-in from UTG+1, this is Big Blind's continuing range (call or shove) rather than an opening range.
This chart compares only shove and fold in a short-stack model. Smaller raises or limps can still matter in the full game; they are not evaluated here.
Model: chip-EV; 0.125bb ante per player, not a big-blind ante. Stacks are measured before posting blinds and antes. Solver 0.2.1. The opponent is already all-in; this is a continue-or-fold decision.

- Big Blind calls 21% of hands at 8bb effective, 9-max. The chart compares only the listed all-in and fold decisions.

- This is a chip-EV baseline for a restricted shove/fold model. It does not compare limps, smaller raises or postflop play, and it is not a guarantee of unexploitable multiplayer play. Separate exploit solves target specified opponent tendencies.
