progressBTN vs CO open at 30 BB
8-max MTT · ante 12.5 % · chip EV
BTN facing a CO open at 30 BB
The cutoff opens to 2 BB and the action reaches the button with 30 big blinds. The book folds 77% of hands, calls with 12%, 3-bets to 5.5 BB with 11%.
Always 3-bet: AA, AKs, AKo, AQo, A8o, A2s, KK, K7s, K6s, QQ, JJ, 88.
Always call: AJs, AJo, ATo, A9s, A7s, A6s, KJs, KJo, KTs, KTo, K9s, QJs and 8 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.
