How SB opens at 8 BB
When the action folds to the Small Blind with 8 big blinds (8-max MTT with ante), the book plays 79% of hands: all-in with 71%, and a limp with 8.0%. The other 21% fold.
Always all-in: AKs, AKo, AQs, AQo, AJs, AJo, ATs, ATo, A9s, A9o, A8s, A8o, A7s, A7o, A6s, A6o, A5s, A5o and 95 more.
Mixed hands (the book splits them between actions): AA, KK, QQ, JJ, J3o, J2o, TT, T9s, T8s, T7s, T6s, T4o, T3o, 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 8 BB: BTN 45%. 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): T3o 50%, 83s 50%, 95o 48%, 54o 56%, 82s 38%, 73s 62%, plus 3 more mixed hands. These are the hands worth drilling, because a small change in the opponents or the stack flips them.

One short lesson a day, each with a worked example in exact numbers: chips vs. money, the bubble factor, who feels the pressure, payout structures, satellites. No account needed.
Numbers come from the progressGTO solution book (v14, chip EV, 8-max, ante 12.5 %): our own equilibrium computation with a modelled postflop. It is an approximation, not an exact solution, and it keeps improving. Hover or tap a hand to see its exact frequencies.
