Manage Repertoire

A repertoire is a collection of chess variations that you want to study, usually organized by opening. The system stores it as a standard PGN file but includes specialized Build and Train modes for constructing and memorizing specific lines.

You can start from the main screen by clicking Create Repertoire, or navigate to the Files page, select Create, and choose Repertoire. Once opened, variations can be added immediately.

Open Build mode by selecting the Build button in the side panel.

  1. Make the relevant opening moves (e.g., Ruy Lopez moves)
  2. Click Set as Start to establish the repertoire root

Build mode displays commonly played moves from each position using reference database data, showing win rates and current coverage.

  • Go to your next gap — jumps to the next uncovered position
  • Go to your biggest gap — jumps to the position with the most uncovered lines

Coverage measures your preparation depth for opponent responses. A variation is “completely covered” when extended to a position with fewer games than the target threshold specified in Settings > Repertoire.

The system automatically handles transpositions, recognizing when positions reachable through different move orders have already been prepared.

After building lines, click Train to drill them. The interface shows repertoire positions and requires you to find the correct move.

Rate your recall difficulty on a scale of 1-4 after each move. The system prioritizes difficult moves using spaced repetition. Keyboard shortcuts 1-4 enable quick rating.

The progress bar displays:

  • Current session practice percentage
  • Moves practiced count
  • Correct/incorrect statistics
  • Overall accuracy percentage

When positions require review, a symbol appears next to the filename in the Files page.
