How BTN opens at 12 BB
When the action folds to the Button with 12 big blinds (8-max MTT with ante), the book plays 40% of hands: a raise to 2 BB with 11% and all-in with 30%. The other 60% fold.
Always raised: AA, AKs, AQs, KK, KJs, KTs, K9s, K8s, K8o, K7s, K3s, K2s, QQ, Q7s and 7 more.
Always all-in: AKo, AQo, AJo, ATs, ATo, A9s, A9o, A8s, A8o, A7s, A7o, A6o, A5s, A5o, A4s, A4o, A3s, A3o and 32 more.
Mixed hands (the book splits them between actions): AJs, A6s, K7o, K6s, K5s, K4s, QTs, Q4s, 77.
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 12 BB: CO 32%, SB 82%. 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): Q4s 44%, K7o 60%. These are the hands worth drilling, because a small change in the opponents or the stack flips them.
