When a chess report should say nothing
Most games have no repeated departure worth naming. A silent report is a feature. Forcing a weakness onto a thin sample is how blogs invent homework.
Chessigma only names a position when both candidate moves have a real sample and the score gap is larger than a pair of upsets. If that bar is missed, the page should say so.
One-off experiments are not repertoire problems
Trying a queen excursion once is not a habit. The report should ignore it until the other move you usually play, and this experiment, both have enough games.
Colour changes mid-comparison are also noise. Compare White with White.
What silence is telling you
Either you followed your usual move, or you left book in a way you have not repeated. Neither needs a fake “blunder on move 18” headline.
Use an engine separately if you want tactics from that one game. Do not ask a history tool to pretend it found a pattern.
Frequently asked questions
Did the import fail if the report is empty?
Usually not. Empty means nothing cleared the threshold.
Can I lower the threshold?
Not from the UI. A lower bar would just report stories.
Chessigma imports public Chess.com and Lichess history and reports repeated choices — not engine grades. Import your games · Methodology
