Find the openings costing you points
The fastest way to find your chess weaknesses is to rank everything you play by result. Audit Chess lists every opening in your history, sorted by score, so the lines quietly costing you points rise to the top. Instead of guessing which openings hurt you, you see them ranked - with the games behind each one - and can drill exactly those. It goes beyond openings too: the same analysis surfaces the mistakes you repeat, your weakest endgames, and the winning positions you throw away. Paste your Lichess or Chess.com username to get the full breakdown. Free, no account, runs on your device.
Every opening, ranked by result
A sortable table shows every opening you play with its score, so "I think I’m bad at the Caro-Kann" becomes a fact you can act on. Sort by worst result and you have your study list.
Weaknesses beyond the opening
Openings are only one source of lost points. Audit Chess also flags recurring middlegame blunders, weak endgame types and blown winning positions, so "find my weaknesses" covers the whole game, not just move one.
