progressSB vs CO open at 12 BB
8-max MTT · ante 12.5 % · chip EV
SB facing a CO open at 12 BB
The cutoff opens to 2 BB and the action reaches the small blind with 12 big blinds. The book folds 76% of hands, calls with 2.1%, goes all-in with 22%.
Always all-in: AA, AKs, AKo, AQs, AQo, AJs, AJo, ATs, ATo, A9s, A9o, A8s, A8o, A7s and 25 more.
Always call: KTo, K9s, QTs, JTs.
The small blind calls rarely: it is out of position against the raiser and the big blind can still squeeze behind, so the book prefers to either 3-bet or fold.

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.
