progressBTN vs CO open at 12 BB
8-max MTT · ante 12.5 % · chip EV
BTN facing a CO open at 12 BB
The cutoff opens to 2 BB and the action reaches the button with 12 big blinds. The book folds 81% of hands, calls with 7.1%, 3-bets to 4 BB with 0.1% and goes all-in with 12%.
Always all-in: AA, AKs, AKo, AQs, AQo, AJs, AJo, ATs, ATo, A9s, A9o, A5s, A4s, A2s and 4 more.
Always call: KQs, KQo, KJs, KJo, KTs, K9s, 88, 55.
The button is in position against the raiser and only the blinds are left behind, which is why it calls far more often than the blinds do.
