How SB opens at 18 BB
When the action folds to the Small Blind with 18 big blinds (8-max MTT with ante), the book plays 86% of hands: a raise to 2.5 BB with 4.4% and all-in with 29%, and a limp with 52%. The other 14% fold.
Always raised: KQs, Q8o, Q7o.
Always all-in: AQo, AJo, ATo, A9o, A8o, A7o, A6o, A5o, A4s, A4o, A3s, A3o, A2s, A2o, KJo, KTo, K9o, K8o and 18 more.
Mixed hands (the book splits them between actions): AKs, AKo, AQs, A9s, A8s, A7s, A6s, A5s, KQo, KJs, K7s, K6s, K3o, K2o and 18 more.
At this depth the open is a small raise, with some hands going all-in directly.
Next to it at 18 BB: BTN 40%. 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 48%, 64o 52%, 94o 76%. These are the hands worth drilling, because a small change in the opponents or the stack flips them.
