progressSB vs CO open at 30 BB
8-max MTT · ante 12.5 % · chip EV
SB facing a CO open at 30 BB
The cutoff opens to 2 BB and the action reaches the small blind with 30 big blinds. The book folds 73% of hands, calls with 11%, 3-bets to 6.5 BB with 8.5% and goes all-in with 7.1%.
Always 3-bet: AA, AKs, AQs, AJs, ATs, A9o, A8o, KK, KQs, QQ.
Always all-in: AQo, KQo, JTs, 88, 66.
Always call: ATo, KJs, KJo, KTo, K9s, K8s, QTo, JTo, T8s, 98s, 87s.
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.
