Chess weaknesses
A weakness is not a single mistake: it is a mistake that repeats. Here are the 40 weaknesses ChessPivot detects automatically in your games, and how to fix each one.
To find them, ChessPivot analyses all of your games and only flags a pattern when it recurs — never a one-off blunder. Each guide explains the weakness, how to avoid it, and offers targeted exercises.

Frequently asked questions
How does ChessPivot detect my weaknesses?
By analysing your games, sometimes several hundred of them: it spots the patterns that recur, not one-off moves. A weakness is only flagged when it repeats.
What is the difference between a mistake and a weakness?
A mistake is a single move. A weakness is a mistake that keeps coming back — for example hanging a piece in quiet positions, game after game.
Do I need an account to use these guides?
No. Each guide explains the weakness and offers exercises without an account. Personalised tracking of your own games does require signing in.
