How BTN opens at 25 BB
When the action folds to the Button with 25 big blinds (8-max MTT with ante), the book plays 44% of hands: a raise to 2 BB with 44% and all-in with 0.1%. The other 56% fold.
Always raised: AA, AKs, AKo, AQs, AQo, AJs, AJo, ATs, ATo, A9s, A9o, A8s, A8o, A7s and 71 more.
Mixed hands (the book splits them between actions): A2o, K7o, J4s, T8o, 98o, 75s, 22.
At this depth the open is a small raise, with some hands going all-in directly.
Next to it at 25 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): K7o 54%, A2o 56%, 98o 40%, T8o 68%, J4s 70%. These are the hands worth drilling, because a small change in the opponents or the stack flips them.
