Candidate Move Trainer
More actions
Location: Trainer > Candidate Move Trainer
The Candidate Move Trainer presents you with a position from your repertoire (or Custom FEN) and challenges you to calculate the strongest candidate moves. Your answers are evaluated against Stockfish analysis, helping you improve your move selection, deepen your calculation ability, and sharpen your instincts for identifying the best options in critical positions.
This allows you to:
- + Practice identifying the strongest candidate moves under time pressure
- + Compare your chosen moves directly against Stockfish evaluations for objective feedback
- + Develop disciplined calculation habits by ranking multiple candidate moves
Controls
The Controls section lets you choose how to start your training session. You can paste a Custom FEN and click Train to begin, or click the Random button followed by Train to start with a random position from your repertoires. You can also set a countdown timer to challenge yourself to calculate quickly and make decisions under time pressure. Once the session has started, you can click Quit at any time to end the exercise and view your results.
Chessboard Card
The Chessboard Card is where you make your move selections. Simply move your pieces to choose a candidate move — arrows will appear on the board to visualize your guesses. During training, all arrows appear in dark grey. Once the training move is completed, results are displayed using color-coded feedback:
- ◦ Green: Your guess matched one of the top moves according to Stockfish evaluation
- ◦ Red: Your move was outside of the top five engine choices
- ◦ Grey: Moves you missed — other strong alternatives from the engine
This visual feedback allows you to instantly see how your candidate moves compare to engine preferences and reinforces pattern recognition through repetition.
Your Guesses
The Your Guesses section appears after you start training. You’ll see how many possible candidate moves exist — up to a maximum of five, though there may be fewer if the position has limited viable options. You can reorder the moves by dragging and dropping them or using the up and down arrows to rank them by strength. Once satisfied, click Submit to view your results.
- ◦ Reorder your guesses based on perceived move strength
- ◦ Click Submit to receive instant feedback with evaluations and continuations
- ◦ Correct guesses are marked with a green check, incorrect ones with red, and missed moves are shown in grey
Analytics Card
The Analytics Card provides supporting data and quick access to related reference tools. It includes several sources you can use to explore or load positions for further practice:
- ◦ My Repertoire Moves: Quickly select a position directly from your repertoires
- ◦ Position Library: Browse stored positions from your personal library
- ◦ Opening Library: Access a library of all named chess openings for quick setup and exploration
By practicing regularly with the Candidate Move Trainer, you’ll develop faster decision-making, stronger calculation discipline, and a deeper understanding of which moves truly matter in critical positions.
