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: stack-to-pot ratio.
  2. After feedback Calculate SPR before deciding whether a hand can play for stacks.
  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 stack-to-pot ratio, 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

Playing one-pair hands the same way at low and high SPR.

Drill it

Calculate SPR before deciding whether a hand can play for stacks.

Practice prompts

  • Before reviewing a hand, write the spot label: stack-to-pot ratio.
  • Calculate SPR before deciding whether a hand can play for stacks.
  • Save one repeated mistake label for tomorrow instead of adding a new topic immediately.
