How BTN opens at 17 BB
When the action folds to the Button with 17 big blinds (8-max MTT with ante), the book plays 41% of hands: a raise to 2 BB with 23% and all-in with 17%. The other 59% fold.
Always raised: AA, AKs, AKo, AQs, AQo, AJs, ATs, A9s, A8s, A7s, KK, KJs, KTs, KTo and 33 more.
Always all-in: ATo, A9o, A8o, A7o, A6s, A6o, A5s, A5o, A4s, A4o, A3s, A3o, A2s, A2o, KQo, Q9s, J9s, T9s and 7 more.
Mixed hands (the book splits them between actions): AJo, KQs, KJo, K7o, QJo, Q2s, JTs, JTo, J5s, 86s, 76s, 55.
At this depth the open is a small raise, with some hands going all-in directly.
Next to it at 17 BB: CO 30%, SB 85%. 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): 86s 46%, J5s 38%, 76s 62%, Q2s 64%, K7o 32%. These are the hands worth drilling, because a small change in the opponents or the stack flips them.
