8-max MTT · ante 12.5 % · folded to the Under the Gun · chip EV
When the action folds to the Under the Gun with 40 big blinds (8-max MTT with ante), the book plays 17% of hands: a raise to 2 BB with 17%. The other 83% fold.
Always raised: AA, AKs, AKo, AQs, AQo, AJs, AJo, ATs, ATo, A9s, A8s, A7s, A6s, A5s and 17 more.
Mixed hands (the book splits them between actions): A4s, A3s, A2s, KTo, K8s, K7s, QJo, Q9s, J9s, T9s, 55.
At this depth everything opens with a small raise; all-ins appear only later, against 3-bets.
Next to it at 40 BB: UTG+1 20%. Seats closer to the button open more here, because fewer players are left to wake up with a big hand.
Closest decisions (the book opens them only part of the time): A3s 48%, 55 38%, K8s 30%, A4s 74%, KTo 26%, Q9s 74%, plus 1 more mixed hands. These are the hands worth drilling, because a small change in the opponents or the stack flips them.
The book opens 17% of hands here, 17% at 38 BB and 17% at 45 BB. These leave it: A3s, 55.
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.
