Build a repertoire from your Lichess or Chess.com games

ChessFlux can build your repertoires from the games you already play on Lichess or Chess.com. It only needs your username: only your public games are read, and nothing is posted to your account.

Start reading

On the Repertoires screen, the “+” button offers “From my games”. Pick the site, then type your username: ChessFlux checks it and shows your profile before starting anything (figure 1).

1 The site you play on: Lichess or Chess.com.

2 Your username. The green check confirms it exists.

3 The profile found: blitz and rapid ratings, number of games.

4 Reading covers your last 100 rapid and blitz games.

Reading happens in front of you: each game replays on the board and the repertoires take shape as it goes (figure 2). You can keep browsing in the meantime; the “Reading…” row in the list follows the progress.

Check the preview before creating

When reading is done, the preview lists the repertoires found: one for White, and one per first opponent move as Black. Uncheck the ones you don’t want, then check each one’s coverage and points to decide (figure 3).

3 Points to decide, spotted in your games.
4 Creates all checked repertoires at once.

A point to decide flags a spot where your games give no clear answer:

You hesitate here: you play two moves almost equally often.
Gap: the opponent played a move several times and you have no fixed reply.
Not working: your move scores badly; ChessFlux shows the most played move on Lichess.
Mistake: the engine prefers another move and shows how much yours loses.

Key takeaway

A repertoire built from your games describes what you play, not necessarily what you should play. The points to decide are where you fix it.

You settle these points later in the lesson: keep your move or switch to the suggested one. You can also decide later; the repertoire stays usable.
