What is a three-bet in poker?

A three-bet is the first re-raise before the flop. It pressures the opener, builds value with strong hands, and can use blocker-heavy bluffs when ranges and positions support it.

Practice this as a decision, not a definition.

Use 3-bet defense trainer to turn the idea into spot reps, EV feedback, and a review cue you can repeat away from live play.

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: three-bet basics.
  2. After feedback Sort three-bet hands into value, bluff, and mixed candidates by opener position.
  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 three-bet basics, 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

Thinking every three-bet is a premium hand or every suited ace is automatically a bluff.

Drill it

Sort three-bet hands into value, bluff, and mixed candidates by opener position.

Practice prompts

  • Before reviewing a hand, write the spot label: three-bet basics.
  • Sort three-bet hands into value, bluff, and mixed candidates by opener position.
  • Save one repeated mistake label for tomorrow instead of adding a new topic immediately.
