Import PGN from Lichess or Chess.com

ChessFlux accepts PGN from a file, pasted text and compatible links such as some Lichess studies or Chess.com games. The right reflex is to treat the import as a starting point, not as the final truth.

Before importing, ask yourself what you want to keep: a precise line, a model game, a full study, or only a line you went wrong in. The clearer the goal, the more readable the repertoire stays afterwards.

1 Choose the side you play in this repertoire.
2 Give it a clear name right away: color, opening, goal.
3 Pick “Import a PGN” as the source.
4 Paste the PGN of your study or game.

Prepare the source

If you import a long PGN, first check that it doesn’t mix too many unrelated games. A Lichess study can hold several chapters; an annotated game can include many sidelines. That information is useful, but it can make the tree too dense for a first session.

Keep comments that explain a plan or a trap.
Avoid importing several openings into the same repertoire.
Give the repertoire a clear name: color, opening, goal (figure 1, marker 2).

Key takeaway

An import is successful when you can start training right after and understand why each branch exists.

Clean up after the import

Once the PGN is in ChessFlux, open the lesson and walk through the first moves in the move list (figure 2). If a line doesn’t fit your style or a position you will play, leave it aside. The repertoire should guide your practice, not archive everything ever played.

Figure 2 The lesson of an imported repertoire: board, moves and comments.

1 The main line and its branches. Spot the sidelines to drop here.

2 Comments imported with the PGN. Keep the ones that explain a plan or a trap.

3 Step move by move to check each branch.

If you import your own games, keep mostly the moments where you hesitated or lost the thread. They are the best candidates for a quick review: they tie opening work directly to your real problems.

Test right away

Finish with a short training session. If you often get stuck at the same spot, that’s not a failure: it’s the signal to add a note, shorten the branch or analyze the position before going on.
