Turning a Lichess Study Into a Trainable Repertoire

What a study is good at

Lichess studies are excellent. They are free, they hold variations and comments, they share with one link, and they are the most convenient place to work something out.

What they are not is a way of remembering it.

A study is read. You open it, move through the moves, and everything is shown to you. That trains recognition, which decays slowly and is not the ability a game asks for. We go through that distinction in why you forget chess openings.

Getting the moves across

The mechanical part is genuinely trivial.

From the study. Open it, find the download or export option, and you get a PGN file containing every chapter. If you only want one chapter, export that chapter alone.

Into a trainer. Almost anything that stores repertoires reads PGN, so the file goes straight in. Some tools also take a study link directly, which saves the download step.

That is it. Thirty seconds, and now you have four hundred positions and a problem, which is that none of them are knowledge yet. That problem has a name and an article: repertoire debt.

The three steps that actually matter

Cut it down first. A study is somebody’s complete treatment of a subject, which is not the same as your repertoire. Delete the lines you will never play. Shorten anything that runs past the point where you understand it. Most imports should lose a third or more before you train a single position.

Pick your side. Studies often cover both colours, or give several options against the same move. A repertoire needs one answer per position. Choose it now, while you still remember why, rather than being asked mid-session.

Keep the comments that give reasons. A study’s annotations are the most valuable thing in it, and they usually survive the import. Prune the ones that only say “best move” and keep the ones that say why. There is a method in how to annotate your own opening lines.

What changes once it is a repertoire

You stop choosing what to look at. That is the entire difference and it is larger than it sounds.

In a study you revisit whatever you happen to open. In a repertoire the scheduler decides, and it picks the positions you are closest to forgetting, which are rarely the ones you would have chosen. The schedule is in how often to review chess openings.

You also stop being shown the answer. Instead of reading a move you produce it, which is harder, slower and the only version that transfers to a game.

Keep the study

Do not delete it. The two things do different jobs and it is worth having both.

The study stays as your working document: the place to think, to write longer notes, to share a line with somebody. The repertoire is where the same content goes to be remembered.

When you change your mind about a line, change it in both. That is the small ongoing cost of the arrangement, and it is much smaller than the cost of a repertoire you never review.

Chess Prep Pro imports Lichess studies and PGN directly, and exports back to PGN whenever you want, so nothing you build is locked into one place.
