This book develops the endgame ideas that help you recognise those changes. It introduces M, Q and stack zones, then connects them to all-in decisions, isolation and play at short-handed tables. The goal is to understand what your available chips allow you to do before choosing a line. A hand cannot be judged by its cards alone when the blinds threaten your stack or the table has fewer players. Effective stacks, the price of a call and the action still to come influence the decision. The material provides a framework for reviewing those pressures without promising a universal push-or-fold rule for every tournament. The detailed poker situations book supplies further examples involving the bubble, ICM and final-table decisions. ## What you will learn - Read stack pressure using M, Q and effective M - Consider fold equity and the risk of all-in decisions - Adjust your thinking for short-handed and heads-up play A taste of the lesson A stack of 12,000 chips with blinds of 500/1,000 has 12 big blinds. Without antes, its M is 12,000 ÷ 1,500 = 8. These measurements describe different aspects of the stack. Neither one tells you automatically to shove: position, the action before you and opponents’ calling ranges still matter. A short learning example adapted from this book. The full lessons and explanations are in the app. ## Inside this book ### Endgame Fundamentals (M, Q, Zones) Learn what M and Q describe and how stack zones frame an endgame decision. Relate your chips to the cost of staying in the tournament and the surrounding field. These measures are starting points for analysis, not substitutes for observing the actual action. **Explore the lessons 9 lessons** - Endgame and Inflection Points - Magriel's M-Ratio: Fundamentals - Q-Ratio: Stack Size Relative to the Field - The Zone System Based on M-Ratio - Yellow Zone Strategy (M 10-20) - Orange Zone Strategy (M 5-10) - Red Zone Strategy (M \< 5) - Multiple Inflection Points - Inflection Points in Practice ### All-In Math and Tactical Tools Connect all-in calculations to practical tactics such as isolation. Compare the amount you risk with the pot you can win, and ask which players can still act. A profitable-looking confrontation can change when another stack is able to enter the pot. **Explore the lessons 4 lessons** - Isolation: When You Target One Player - Calculating Pot Odds in All-In Spots - All-In Decisions Based on Pot Odds - The 10:1 Rule and Pot Odds ### Short-Handed and Heads-Up Strategy Study how fewer players and heads-up play alter the table. Reconsider hand values, effective M and the usefulness of deception or slowplaying. The remaining opponent's tendencies matter, so a short-handed adjustment should still have a reason rather than becoming automatic aggression. **Explore the lessons 14 lessons** - Short-Handed Play: Effective M-Ratio - Effective M in Practice and Endgame Tactics - Preflop Slowplay with Few Players - Postflop Slowplay and Cooperative Play - Heads-Up Fundamentals: Strategic Principles - Heads-Up Strategic Advice - Heads-Up M-Ratio and Basic Preflop Strategy - Heads-Up: Preflop Play - Heads-Up: Preflop Pot Odds - Heads-Up: Position and Bet Sizing - Heads-Up Play from the Small Blind/Button - Heads-Up Play from the Big Blind - Heads-Up: Battles Between Unpaired Hands - Dominance in Heads-Up Play ## Understand what a shrinking tournament stack means Tournament endgames are easier to study once you can relate the stack to the cost of staying at the table. If you have 3000 chips and an orbit costs you 500, your M-ratio is 6. This expresses pressure on the stack; it is not a forecast of how many hands you will win. An M-ratio of 6 does not make every hand an automatic shove. Position, previous action and the opponents’ stacks still matter, as does the price of an all-in call. Use the book’s zone framework to organise the situation, then examine the decision itself. This is particularly useful when moving from a full table to short-handed or heads-up play. ## How to study and apply these lessons Set up a simple tournament example with blinds, stack sizes and the action before your turn. State which stack is effective and how much a call would cost. Before choosing an all-in, distinguish winning the existing pot without a showdown from being called. Those two outcomes need different reasoning even though both begin with the same action. Use the explanations to identify the assumption behind your answer: opponent range, calling frequency or stack pressure. Then change one detail and ask whether the decision should change too. Do not treat one winning tournament hand as proof that a tactic always works. Continue with the poker situations book to compare this framework with more complex pressure spots, and remember that tournament equity and chip equity need not be identical. ## Keep exploring ### [Pot odds and EV: put numbers behind a call](https://pokerwise.app/guides/pot-odds-and-expected-value/) Calculate the break-even equity for a call, distinguish pot odds from implied odds and understand why a good decision can lose.
