Decision fatigue is the drop in decision quality that comes with the number of decisions made and the time spent at the table. The same hand is often played differently in hour four than in hour one, and your own session notes can show when. ## What is decision fatigue in poker? It is a drop in decision quality as a session runs long. Hundreds of decisions, each with a price to check and a range to consider, add up, and the first thing to go is usually the work that takes effort. You see it in skipped math, default calls and faster actions. - Skipping the pot odds on a call that looks routine. - Calling by default because folding feels like giving up. - Acting faster than you did an hour ago. ## How do I find my own curve? Use the hands and notes from your last ten sessions. Mark the time of each hand where you were unsure and look for when they start. If most of them fall after the third hour, that is your curve, and it tells you where a break or a stop rule belongs. The curve is personal, so measure your own and set your breaks by it. ## How do I compare early and late hands? Take a similar spot early and late and compare the choice with the price. A pot-sized bet needs 33.33% equity to call, and a half-pot bet needs 25.00%. If you called the same draw against the same bet at hour one with the math and at hour four without it, the hand did not change, the decision process did. - [Pot odds calculator](https://georgelipoker.com/tools/pot-odds-calculator.md) - [Pot odds by bet size](https://georgelipoker.com/pot-odds.md) - [Outs by street](https://georgelipoker.com/outs.md) ## How long should a session be, and when should I take breaks? Set the length and the breaks in advance, with fixed times. A short break at a fixed time gives you a place to run your routine and does not depend on how you feel when the time comes. Plan the session to end before the point where your unsure hands begin to cluster. ## What is a stop rule? A stop rule is a written instruction to leave when two named signs appear, decided before the session. Choose signs you can observe, such as skipping the math twice or playing a hand you would normally fold. Two signs are better than one because a single slip can be a one-off. A rule you wrote before the session costs you nothing to follow. A rule you invent in hour four has to be argued with. - [Building a between-hands routine](https://georgelipoker.com/mental-game/building-a-between-hands-routine.md) - [A pre-session and post-session checklist](https://georgelipoker.com/mental-game/a-pre-session-and-post-session-checklist.md) - [Who the coaching is for: decisions late in a session](https://georgelipoker.com/stories/decisions-late-in-a-session.md) ## What does decision fatigue look like in a hand history? Look for three things in the notes and the history: the time stamps of hands you marked as unsure, the number of hands you played per hour late in the session compared with early, and the calls you made without writing a price. None needs special software. A spreadsheet with a row per unsure hand and a column for the hour is enough, and after ten sessions the pattern is usually clear. If the pattern is not clear, that is also information: it means your decisions held, and the plan to shorten the session is unnecessary. Keep the stop rule anyway, because it is cheap. ## What can I do before my next session? 1. Write the time of your last ten unsure hands and note the earliest. 2. Set a session length shorter than that point, with a break in the middle. 3. Write a stop rule with two signs, such as skipping the math twice or playing a hand you would normally fold. ## Questions **How long should a session be?** The answer is personal. Find the point where your own unsure hands start, and plan to stop before it. **Do breaks really help?** Scheduled breaks at fixed times give you a place to run your routine, and because the time is set in advance, the break happens even on the day you would rather keep playing. **What if I cannot leave a game?** Use the between-hands routine and the fixed check on every call, and keep the stop rule for the next time you can leave.
