Mistakes that repeat

How to stop blundering in chess (for real)

“You don't make a hundred different mistakes. You make ONE that repeats — and until you name it, it will keep draining your rating.”

Generic advice ("check your checks", "look at the whole board") fails because it treats every mistake as the same one. They are not: hanging a piece, allowing a tactic and burning your clock are different diseases with different cures.

What works is a diagnosis over YOUR real games: which concrete pattern repeats, how many rating points it costs, and a daily exercise drawn from your own positions — not invented puzzles.

Fix My Chess reads your latest Lichess or Chess.com games with a deterministic engine (no AI making things up), names your dominant leak citing your exact moves, and a master trains it with you 5 minutes a day.

Is this your leak?

Paste your Lichess or Chess.com username and in 60 seconds you will know which pattern is costing you points — with your own moves cited as proof. Free, no account.
