progressBTN vs CO open at 22 BB
8-max MTT · ante 12.5 % · chip EV
BTN facing a CO open at 22 BB
The cutoff opens to 2 BB and the action reaches the button with 22 big blinds. The book folds 79% of hands, calls with 9.2%, 3-bets to 4.5 BB with 4.2% and goes all-in with 7.7%.
Always 3-bet: AKs, AQs.
Always all-in: AKo, AQo, KQo, JTs, T9s, 88, 44.
Always call: ATo, A9s, A6s, KJs, KJo, KTo, K9s, 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.

One short lesson a day, each with a worked example in exact numbers: chips vs. money, the bubble factor, who feels the pressure, payout structures, satellites. No account needed.
Numbers come from the progressGTO solution book (v14, chip EV, 8-max, ante 12.5 %): our own equilibrium computation with a modelled postflop. It is an approximation, not an exact solution, and it keeps improving. Hover or tap a hand to see its exact frequencies.
