Welcome to lesson 7, narrated by Hermes.
Push-fold is the discipline that turns 15bb stacks from "death row" into "easily exploitable spots". When you're short, post-flop play stops mattering, what matters is whether you shove the right hands.
The framework
Sklansky and Chubukov (2005) gave us the first solved push-fold framework: each starting hand has a maximum profitable shove depth versus a random calling range. Above that stack depth, fold. At or below, push, and against perfect defence you cannot lose money.
Modern Nash equilibrium charts refine this with actual ranges on both sides, the SB shover and BB caller both play GTO. The results are similar but the ranges widen slightly because real opponents can't defend perfectly.
Train the most common spot (SB vs BB, 15bb) live with the push-fold trainer. Look up specific hand depths in the SC rankings table.

One question, friend. Pass it and lesson 8 unlocks.
You're in a tournament with twelve big blinds. Action folds to you in the small blind. The big blind is a tight regular. What is the spot called and what's usually the right play with a wide chunk of hands?
