How CO opens at 24 BB
When the action folds to the Cutoff with 24 big blinds (8-max MTT with ante), the book plays 33% of hands: a raise to 2 BB with 33%. The other 67% fold.
Always raised: AA, AKs, AKo, AQs, AQo, AJs, AJo, ATs, ATo, A9s, A9o, A8s, A8o, A7s and 54 more.
Mixed hands (the book splits them between actions): A5o, K9o, Q4s, T9o, 22.
At this depth the open is a small raise, with some hands going all-in directly.
Next to it at 24 BB: HJ 27%, BTN 43%. 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): 22 52%, T9o 38%, A5o 74%, K9o 24%. These are the hands worth drilling, because a small change in the opponents or the stack flips them.
