How SB opens at 40 BB
When the action folds to the Small Blind with 40 big blinds (8-max MTT with ante), the book plays 86% of hands: a raise to 3.5 BB with 29% and all-in with 0.1%, and a limp with 57%. The other 14% fold.
Always raised: AKs, AKo, AQs, AJs, A8s, A7s, A7o, A6s, A6o, A3s, A2s, KJs, KTo, K9o and 9 more.
Mixed hands (the book splits them between actions): AA, AQo, AJo, ATs, A9s, A8o, A5s, A5o, A4s, A4o, A3o, A2o, KK, KQs and 61 more.
At this depth everything opens with a small raise; all-ins appear only later, against 3-bets.
Next to it at 40 BB: BTN 48%. 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): 94o 48%, 93o 42%, 74o 38%, 64o 62%, 84o 32%, T2o 76%, plus 1 more mixed hands. These are the hands worth drilling, because a small change in the opponents or the stack flips them.
