8-max MTT · 12.5% ante from each player · chip EV · each position across 10–100 BB
Choose a position and see how its opening range changes with the stack, from 8 to 100 big blinds, together with the big blind defense against that position. Each percentage links to the full hand-by-hand chart.
Ranges widen the later the position: in the book UTG opens 16%–19% of hands depending on stack, the button 39%–50%, and the small blind 79%–90%. The numbers come from our own solution book (v17d), an approximation of equilibrium with a modelled postflop.

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 (v17d, chip EV, 8-max, 12.5% ante from each player): 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.
