How BTN opens at 20 BB
When the action folds to the Button with 20 big blinds (8-max MTT with ante), the book plays 41% of hands: a raise to 2 BB with 32% and all-in with 8.9%. The other 59% fold.
Always raised: AA, AKs, AKo, AQs, AQo, AJs, AJo, ATs, ATo, A9s, A8s, A7s, A6s, A5s and 50 more.
Always all-in: A9o, A8o, A7o, A6o, A5o, Q9s, T9s, 87s, 44, 33, 22.
Mixed hands (the book splits them between actions): A4s, A4o, KQo, QJo, QTs, JTs, J9s, J8o, J5s, T6s, 96s.
At this depth the open is a small raise, with some hands going all-in directly.
Next to it at 20 BB: CO 31%, SB 87%. 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): J5s 56%, 96s 30%, J8o 24%. These are the hands worth drilling, because a small change in the opponents or the stack flips them.
