The Preflop GTO Trainer in Lucid Poker

Learn how to use Lucid Poker's free Preflop GTO Trainer to drill preflop decisions, review your mistakes, and explore solver solutions in a few taps.

Quick answer
The Preflop GTO Trainer lets you drill real preflop spots against a GTO solution, get instant feedback on each decision, and review every hand after your session. Preflop drilling is free for all users.

How it works

The Preflop GTO Trainer puts you through a series of real preflop spots and scores each decision against the GTO solution. You choose a game type, set a hand count, and work through each situation one at a time. After each decision, Lucid tells you whether your play was correct, solver-approved at a mixed frequency, or a mistake.

Preflop drilling is free for all users. Custom drill filters are a Pro-only feature.

Tip

Not every correct play is pure. If Lucid marks a move as solver-approved at a low frequency, that is still a valid action. The goal is to understand the range, not just the top play.

Reading the feedback

After each decision, Lucid shows you the solver's verdict. Three possible outcomes:

  • Correct. Your action matched the solver's primary recommendation.
  • Solver-approved at a low frequency. Your action is in the GTO range but not the top play. Not a mistake, but worth studying.
  • Mistake. Your action was not part of the solver's strategy. Lucid shows the correct play and EV lost.
Example

Scenario: You hold A♥Q♦ facing a raise and a three-bet. In a rake-free sim at this stack depth, the solver folds every time. Four-betting costs roughly half a big blind in EV and shows as a mistake in your review.


Session review and the Sim Browser

After all hands are complete, tap Review Hands to see a summary of every decision. Tap any hand to open it in the Sim Browser and see the full range breakdown for that spot.

Important

The solver range can be tighter than you expect. In spots with a raise and three-bet in front, the continuing range is often very narrow. In many rake-free sims, only aces, kings, ace-king, and queens continue.
