How SB opens at 9 BB
When the action folds to the Small Blind with 9 big blinds (8-max MTT with ante), the book plays 81% of hands: all-in with 66%, and a limp with 15%. The other 19% fold.
Always all-in: AKs, AKo, AQs, AQo, AJs, AJo, ATs, ATo, A9s, A9o, A8s, A8o, A7s, A7o, A6s, A6o, A5s, A5o and 91 more.
Mixed hands (the book splits them between actions): AA, KK, QQ, JJ, J5o, TT, T9s, T8s, T7s, T6s, T6o, T3o, T2s, T2o and 20 more.
At this depth most of the game is push or fold — a small raise is kept only for a few hands that want a call.
Next to it at 9 BB: BTN 44%. 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): T2o 48%, 85o 56%, 75o 56%, 73s 62%, 54o 32%, 82s 72%, plus 2 more mixed hands. These are the hands worth drilling, because a small change in the opponents or the stack flips them.
