How SB opens at 80 BB
When the action folds to the Small Blind with 80 big blinds (8-max MTT with ante), the book plays 90% of hands: a raise to 3.5 BB with 1.6%, and a limp with 88%. The other 10% fold.
Mixed hands (the book splits them between actions): AQs, AJs, KQs, KQo, KJs, KTs, QJs, QTs, Q2o, JTs, T5o, T4o, T3o, T2o and 11 more.
At this depth everything opens with a small raise; all-ins appear only later, against 3-bets.
Next to it at 80 BB: BTN 49%. The small blind only has the big blind behind, but it is out of position after the flop, so it mixes raises, limps and all-ins instead of simply opening wider.
Closest decisions (the book opens them only part of the time): 93o 52%, 94o 54%, 92o 46%, 63o 46%, T2o 58%, 83o 60%, plus 7 more mixed hands. These are the hands worth drilling, because a small change in the opponents or the stack flips them.
What changes around 80 BB
The book opens 90% of hands here, 90% at 70 BB and 86% at 100 BB. These leave it: 92o.
