When to use this guide

  • You know the spot type but want a cleaner reason for the decision.
  • You want practice prompts before opening a trainer session.
  • You need related concepts to review after a missed hand.

One-session loop

Turn the idea into one decision rep.

  1. Before the answer Before reviewing a hand, write the spot label: blind defense.
  2. After feedback Review big blind calls by opener position and ask which hands lost because they could not realize equity.
  3. Next review Save one cue you can reuse in the next trainer session away from live play.

Start with one spot

Do not try to solve the whole topic at once. Start with one spot that matches blind defense, write the decision you would make before seeing feedback, then review two or three similar hands so the pattern has a chance to stick.

Mistake to watch

Calling every hand that looks priced in without checking domination, playability, or postflop position.

Drill it

Review big blind calls by opener position and ask which hands lost because they could not realize equity.

Practice prompts

  • Before reviewing a hand, write the spot label: blind defense.
  • Review big blind calls by opener position and ask which hands lost because they could not realize equity.
  • Save one repeated mistake label for tomorrow instead of adding a new topic immediately.
