How BTN opens at 11 BB
When the action folds to the Button with 11 big blinds (8-max MTT with ante), the book plays 41% of hands: a raise to 2 BB with 5.4% and all-in with 36%. The other 59% fold.
Always raised: AA, AKs, K7s, K7o, K2s, J9o.
Always all-in: AKo, AQs, AQo, AJs, AJo, ATs, ATo, A9s, A9o, A8s, A8o, A7s, A7o, A6s, A6o, A5s, A5o, A4s and 47 more.
Mixed hands (the book splits them between actions): KK, KTs, K9s, K8s, QTs, Q6s, Q5s, JJ, TT, T6s, 99.
At this depth most of the game is push or fold — a small raise is kept only for a few hands that want a call.
Next to it at 11 BB: CO 33%, SB 80%. 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): T6s 50%. These are the hands worth drilling, because a small change in the opponents or the stack flips them.
