About this game

ChessFlux helps you learn your chess openings and never forget them again. Build your repertoire, train move by move, and find your lines when you need them in a game.

YOUR REPERTOIRE, BUILT FROM YOUR OWN GAMES
Enter your Lichess or Chess.com username: ChessFlux reads your latest games and builds your repertoire as you actually play it. One repertoire for White, one per opponent reply for Black. The app spots your hesitations, the moves where you have no answer and the mistakes you keep repeating, then offers to fix them.

GAME DEBRIEF
ChessFlux shows you where you left your repertoire, the opponent moves you don't know yet and the variations that bring you wins, then helps you complete your repertoire at the right spot.

A TREE-STRUCTURED OPENING REPERTOIRE
- Create your openings move by move, with variations and comments
- Organize them in folders, merge several repertoires
- Import a PGN, a Lichess study or a game by link, export and share
- Pick a ready-made opening from the catalog

SUGGESTIONS TO COMPLETE YOUR LINES
Purple arrows show the most played moves on Lichess in each position, with their percentage. The gap radar finds frequent opponent replies your repertoire doesn't answer yet and takes you there.

TRAINING THAT HITS THE MARK
Replay your repertoire on the board until every move sticks. The app comes back to the moves you forget.
- Progressive learning: basics first, then depth
- Full repertoire, random positions, or new moves only
- Targeted review of your weak moves
- Mastery stats for each opening

STOCKFISH ANALYSIS
Evaluation bar, best move, and Stockfish playing the opponent so you can test your lines against the engine.

TACTICAL PUZZLES AND RANKING
Forks, pins, skewers, sacrifices, endgames… Train your tactics by theme or by opening, play in ranked mode to track your puzzle rating, and revisit your mistakes to rework them.

LEAGUES, QUESTS AND STREAKS

• Lessons: ranked opponent replies as arrows, move annotations (!!, !, ?!…), clickable moves in notes
• Repertoire creation: interactive move graph, multi-game PGN, variations kept
• Redesigned opening page, new animations and fixes
