Reading the classification
After analysis, every move in the list carries a colored badge. It’s the fastest summary of the game: a green column tells a solid game, a red spot marks where everything tipped over.
The move list after analysis — every move wears its classification badge.
The ten categories
| Badge | Category | What it means |
|---|---|---|
| Brilliant | A sacrifice or a hard-to-see move that is right. Rare — savor it. | |
| Excellent | A very good move, above what the position demanded. | |
| Best | The engine’s first choice. | |
| Great | Not quite the best move, but without consequence. | |
| Good | A correct move, the position holds. | |
| Book | A known theory move — the game is still “in the book”. | |
| Inaccuracy | A small slip — a few winning percentage points lost. | |
| Mistake | A real problem: the advantage changes hands or melts significantly. | |
| Miss | The missed opportunity — a strong move was there, it wasn’t played. | |
| Blunder | The move that loses. This is the one to understand first. |
The overall logic: categories measure what the move costs in winning percentage, not its beauty. An “ugly” move that loses nothing is Good; a natural move that lets a mate slip away is a Miss.
The current-move card
At the top of the right panel, a card summarizes the displayed move: its classification spelled out, the game’s accuracy, and for faulty moves the exact loss (for example loss −12.4%) — the price of the move in winning percentage.
Accuracy
Accuracy, shown for White and Black, condenses the game into one number: 100% would be the engine’s game. A few orders of magnitude to place yourself: above 90%, a very clean game; between 75 and 85%, a typical club game; below that, the game was strewn with missed opportunities — good news, the graph will show where.
