Blunder Workout

The Blunder Workout takes a different approach from the Opening Workout. Instead of training memorized repertoire lines, it focuses on positions where you made mistakes in your own games. By drilling these specific positions, you build pattern recognition to avoid repeating the same errors.

How It Differs from Opening Workout

The Opening Workout trains you on coach-curated or imported opening lines. The Blunder Workout trains you on positions extracted from your analyzed games -- specifically positions where the engine detected a mistake. This makes it a personalized training tool that targets your individual weaknesses.

Sending Positions to Blunder Workout

Positions enter the Blunder Workout from the game workspace. After analyzing a game with the engine, you can send flagged positions to the workout:

1. Open a game in the game workspace.
2. Navigate to a position that has been classified by the engine.
3. Use the Send to Workout action to open the selection sheet.
4. Choose which classifications to include:
   • Blunders -- Major mistakes that significantly change the evaluation.
   • Mistakes -- Meaningful errors that worsen your position.
   • Inaccuracies -- Minor imprecisions that slightly affect the evaluation.
   • Difficult -- Positions where the best move was hard to find.
5. Confirm to add the selected positions to your Blunder Workout queue.

The Send to Workout sheet lets you choose which types of mistakes to train on

Tip: Start by focusing on blunders only. Once you stop repeating those, expand to include mistakes and inaccuracies for more refined training.

The Carousel Interface

The Blunder Workout presents positions in a carousel format. Each slide shows a position where you made a mistake, and you need to find the correct move. Swipe or tap to navigate between positions.

The workout supports two modes:

• Due Only (SRS mode) -- Shows only positions that are scheduled for review based on the spaced repetition algorithm. Positions you have mastered appear less frequently.
• All Positions -- Shows every position in your blunder collection, regardless of scheduling. Useful for a comprehensive review session.

The carousel interface presents one mistake position at a time

Statistics Dashboard

The Blunder Workout includes a detailed statistics dashboard that tracks your progress across all collected positions.

Overview

• Total positions in your blunder collection.
• Completion rate -- percentage of positions you have answered correctly at least once.
• Classification breakdown -- how many blunders, mistakes, inaccuracies, and difficult positions are in your collection.

Streaks

• Current streak -- how many consecutive correct answers in your current session.
• Best streak -- your all-time longest streak of correct answers.

Trouble Spots

• Positions you have gotten wrong multiple times are highlighted as trouble spots. These are the patterns you most need to work on.

The statistics dashboard provides a detailed view of your training progress

Navigating to Game Context

From any position in the Blunder Workout, you can navigate back to the original game to see the full context. This is helpful when you want to understand why a move was a mistake -- seeing the moves that led to the position and what happened afterward provides valuable context for learning.

Tip: When you encounter a trouble spot repeatedly, go back to the game context and study the position with the engine turned on. Understanding the "why" behind the correct move helps you remember it better than rote memorization alone.

Building a Blunder Collection

The most effective approach is to analyze all your serious games (rated games, tournament games) and send the mistakes to the Blunder Workout. Over time, you build a personalized collection of your most common error patterns. Reviewing these regularly is one of the most efficient ways to improve your playing strength.
