How BTN opens at 70 BB
When the action folds to the Button with 70 big blinds (8-max MTT with ante), the book plays 48% of hands: a raise to 2.5 BB with 48%. The other 52% fold.
Always raised: AA, AKs, AKo, AQs, AQo, AJs, AJo, ATs, ATo, A9s, A9o, A8s, A8o, A7s and 79 more.
Mixed hands (the book splits them between actions): A2o, J2s, T5s, T4s, 97o, 95s, 87o, 85s, 64s.
At this depth everything opens with a small raise; all-ins appear only later, against 3-bets.
Next to it at 70 BB: CO 34%, SB 90%. 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): 97o 50%, 95s 48%, A2o 42%, T4s 42%, T5s 58%, J2s 62%, plus 2 more mixed hands. These are the hands worth drilling, because a small change in the opponents or the stack flips them.
