progressBTN vs CO open at 40 BB
8-max MTT · ante 12.5 % · chip EV
BTN facing a CO open at 40 BB
The cutoff opens to 2.1 BB and the action reaches the button with 40 big blinds. The book folds 75% of hands, calls with 15%, 3-bets to 7 BB with 10%.
Always 3-bet: AA, AKs, AKo, A8o, KK, QQ, JJ.
Always call: AJs, AJo, ATs, ATo, A9s, A8s, A7s, A6s, A5s, KQo, KJs, KJo and 13 more.
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.
