Facing a Hijack open to 2 BB (small blind folds) with 14 big blinds, the big blind folds only 23% of hands, calls 63% and goes all-in with 14%. The big blind already has one blind in the pot and closes the action, so it gets a good price.

Against other openers at 14 BB the big blind continues with: vs BTN 78%, vs CO 75%, vs LJ 77%, vs UTG+1 75%, vs UTG 73%. 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): J5o 32%, J6o 70%, K4o 74%. These are the hands worth drilling, because a small change in the opponents or the stack flips them.
