GTO FisherBuild your decision intuition
Practice equity, range composition, and strategy frequencies.
Decision Science helps you recognize the ingredients of a decision before choosing an action. Use it to practice estimates and range patterns, then connect those ideas to a concrete spot.
Choose one concept
Focus on equity, range composition, a strategy matrix, or action frequency. Ask yourself what the exercise is measuring. Equity against a range and the EV of an action are related, but they are not interchangeable.
Make an estimate first
Look at the board and ranges before revealing the result. Say which hands are strong, which have useful draws, and which blockers may matter. Your estimate is a way to test your understanding, not a score to protect.
Explain the difference
Compare your estimate with the feedback. Inspect specific combos that support or contradict your reasoning, then ask Fisher to connect the details to the wider range pattern.
Apply it in a decision
Move to a related Decision Training spot and use the same observation. After choosing an action, check whether the concept explains the feedback or whether pot size, future betting, or another assumption changes the answer.
