Weakness Trainer

Location: Trainer > Weakness Trainer

The Weakness Trainer focuses on the positions where you’ve struggled most during your training sessions. By tracking your performance in both the Position Trainer and Repertoire Trainer, it identifies weak spots and presents them for targeted practice. This ensures you spend more time reinforcing the areas that need improvement — turning weaknesses into strengths through focused repetition.

This allows you to:

• + Automatically prioritizes the positions you’ve performed worst on during training
• + Helps you convert problem areas into reliable strengths through repetition and review
• + Ensures your practice time is spent where it has the most impact

Controls

The Controls section lists positions marked with a negative score — the ones you’ve struggled with most during Position Training and Repertoire Training. Use this view to jump straight into targeted practice where it’s needed most.

This allows you to:

• ◦ Filter by repertoire: You can select whichever repertoire you want to focus on by using wild card filtering on the repertoire name
• ◦ The positions appear as a paginated list with the repertoire name and opening line — click any entry to load that position into the trainer
• ◦ Include today’s results: Toggle whether to include positions you trained today — useful for reviewing fresh results or resetting for the next session

This allows you to focus your weakness training.

The Chessboard Card displays the position you selected — including its name and line — ready for your attempt.

When in training mode, a Quit button is shown.

When the training position is over, you’ll see Reset, Back, and Next buttons, as well as Flip Orientation. You can also navigate using the left and right arrow keys on your keyboard.

When you end the attempt, the Moves Card appears to let you review the line and compare against your intended repertoire.

Moves Card

The Moves Card appears once you end the training for a position. It allows you to review the correct move sequence in detail, comparing your response against the intended repertoire line. As with other trainers, this card includes visualization tools, annotations, and evaluation options to aid deeper analysis.

• ◦ Review the correct continuation after each attempt
• ◦ Identify recurring mistakes across similar positions
• ◦ Reinforce corrected patterns immediately to strengthen recall

By concentrating your efforts on previously weak areas, the Weakness Trainer ensures that every minute of practice directly contributes to measurable improvement in your repertoire knowledge and consistency.

Personal Note: I use the Weakness Trainer at the end of my study sessions to clean up mistakes from earlier training. It’s the perfect way to end a session — reinforcing the positions I missed so they’re never forgotten again.
