How the BB defends at 8 BB

Against other openers at 8 BB the big blind continues with: vs BTN 73%, vs CO 73%, vs HJ 75%, vs UTG+1 73%, vs UTG 71%. The defence does not simply grow with the position of the opener here; the exact chart for each opener matters.
Closest decisions (the book continues with them only part of the time): K5o 52%, J7o 46%, T6o 54%, 84o 42%, K4o 40%, 95o 66%, plus 3 more mixed hands. These are the hands worth drilling, because a small change in the opponents or the stack flips them.
