Review your real opening decisions

Open RepertoireLab, connect Lichess, and compare recent games with the repertoires you have built.

Analyze Your Games

Stop Studying Openings You Never Face

Opening databases show what could happen. Your Lichess history shows what does happen to you: the defences opponents choose, the sidelines that recur, and the moments when remembered preparation becomes uncertain.

RepertoireLab loads recent games from a connected Lichess account and compares the moves you played with the lines already stored in your repertoire. That turns a large body of theory into a narrower question: where did this game first differ from the preparation you intended to follow?

Find Where Your Preparation Ends

A deviation is useful only in context. The app identifies games in which your move differed from the matching repertoire move and opens the relevant board position. You can see the move played in the game, request a hint, and try to find the saved repertoire move yourself.

A deviation is not automatically a blunder

It means the played move differed from your stored repertoire. Analyze the chess separately before deciding whether the repertoire or the game move should change.

Turn Mistakes Into Focused Practice

At the deviation position, RepertoireLab asks you to find the move from your repertoire. This active step is more revealing than merely reading a move list. If the move feels unfamiliar, you have found a review target. If the saved move no longer makes sense, return to the builder and investigate the line.

Open a game that contains a repertoire deviation.

Try the expected move from the board position, using a hint only when needed.

Analyze and refine the saved line if the game uncovered missing or outdated preparation.

Build Your Repertoire Around Real Games

Use recurring positions as a priority signal. A modest sideline that appears often deserves a clear response and a note. A deep branch you never see can remain shallow. This keeps the repertoire maintainable and connected to practical play.

If you are starting from scratch, the guide to building an opening repertoire explains how to create coverage before depth. If the challenge is retention, use the routine in how to remember chess openings.

Train What Matters Most

Game analysis and scheduled review solve different problems. Game comparison shows where preparation failed under real conditions. Spaced repetition keeps saved lines available between games. Together they create a useful loop: play, analyze, build, train, remember, and play again.

Frequently Asked Questions

Can I analyze my Lichess games?

Yes. RepertoireLab can connect to a Lichess account, load recent games, and compare your moves with the White and Black repertoires saved in the app.

Does RepertoireLab play games for me?

No. RepertoireLab is a repertoire-building and training tool. Games are played on Lichess; RepertoireLab uses imported game data to help you review your opening preparation.

Do I need a Lichess account?

A Lichess account is needed for the connected Lichess workflow. RepertoireLab also supports importing chess notation and PGN files when you want to build lines directly.

How should I use game analysis to improve my openings?

Start with the first meaningful point where your move differed from your saved repertoire. Practise the intended move, investigate the position, and update your repertoire separately when the game reveals a genuine gap.
