How BTN opens at 15 BB
When the action folds to the Button with 15 big blinds (8-max MTT with ante), the book plays 39% of hands: a raise to 2 BB with 17% and all-in with 22%. The other 61% fold.
Always raised: AA, AKs, AKo, AQs, AJs, ATs, KK, KJs, KTs, K9s, K9o, K8s, K8o, K6s and 21 more.
Always all-in: AQo, AJo, ATo, A9o, A8o, A7o, A6s, A6o, A5s, A5o, A4s, A4o, A3s, A3o, A2s, A2o, KQs, KQo and 17 more.
Mixed hands (the book splits them between actions): A9s, A8s, A7s, KTo, K7s, QTo, Q9o, Q3s, J6s, T7s, 86s.
At this depth the open is a small raise, with some hands going all-in directly.
Next to it at 15 BB: CO 30%, SB 84%. Seats closer to the button open more here, because fewer players are left to wake up with a big hand.
Closest decisions (the book opens them only part of the time): Q3s 36%, J6s 34%, Q9o 76%. These are the hands worth drilling, because a small change in the opponents or the stack flips them.
