How BTN opens at 26 BB
When the action folds to the Button with 26 big blinds (8-max MTT with ante), the book plays 44% of hands: a raise to 2 BB with 44%. The other 56% fold.
Always raised: AA, AKs, AKo, AQs, AQo, AJs, AJo, ATs, ATo, A9s, A9o, A8s, A8o, A7s and 73 more.
Mixed hands (the book splits them between actions): A2o, K7o, T8o, 98o, 75s.
At this depth everything opens with a small raise; all-ins appear only later, against 3-bets.
Next to it at 26 BB: CO 34%, SB 88%. 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): A2o 52%, 98o 46%, K7o 66%, 75s 28%. These are the hands worth drilling, because a small change in the opponents or the stack flips them.
