Italian Game · recall each move from memory
Train the moves that decide your games
Build a repertoire, review it with FSRS scheduling, and turn real game mistakes into the next move you practice.
Adaptive FSRS repetition
Every opening position is a flashcard scheduled by the FSRS algorithm. You review each move right before you would forget it – so repetitions land when they actually reinforce memory, not on a fixed drip.
Repertoire explorer
Build, browse, and refine your White and Black opening trees as a connected graph. See the FSRS status of every move at a glance before you turn a line into a focused training session.
Start from the openings you already play
No repertoire yet? OnlyMove reads your recent Lichess and Chess.com games, checks them against a strong engine, and proposes a trusted starter repertoire from the lines you play consistently – review, tweak, and start training in one click.
Learn from your own games
Import your Lichess and Chess.com games. OnlyMove finds exactly where you left your preparation, and lets you fold the fix straight into your repertoire so it enters the review queue.
How it works
A guided loop for building opening knowledge that sticks – import, drill, and repair.
- 1
Import or build
Paste PGN, import a study, or build your White and Black repertoires move by move in the explorer.
- 2
Drill what is due
Train the positions FSRS says are due today. Autoplay skips mastered moves and drops you at the moves that need work.

Track and repair
Import your real games and OnlyMove shows exactly where you left theory – fix it in a click. Moves you played correctly count toward your reviews automatically, so you drill less and focus on what you actually forgot.
Frequently asked questions
What is OnlyMove?
OnlyMove is a web app for learning chess openings with spaced repetition. It turns each move in your repertoire into a flashcard and schedules reviews with the FSRS algorithm so you remember your lines over the long term.
How is OnlyMove different from Lichess or Chess.com?
Lichess and Chess.com are where you play games and browse opening databases. OnlyMove is where you memorize your own openings: it turns your repertoire into FSRS-scheduled flashcards and drills the moves you are about to forget. The two fit together – link your Lichess or Chess.com account to import your real games and see exactly where you left preparation and where to improve.
How is OnlyMove different from Chessable?
Chessable teaches published courses and books you buy and drills them with its own spaced-repetition trainer. OnlyMove trains the repertoire you own – paste your own PGN or bootstrap it from your recent games – and schedules every position individually with the modern FSRS algorithm. Nothing to purchase per opening; you decide which lines to learn.
What is FSRS?
FSRS (Free Spaced Repetition Scheduler) is a modern scheduling algorithm that predicts when you are about to forget a card and reviews it just in time. OnlyMove applies it at the level of individual opening positions.
Do I need a Lichess or Chess.com account?
No. You can sign up with a username and password. Connecting an account is optional: signing in with Lichess is a one-click alternative to a password, and linking Lichess or Chess.com lets you import your real games to find where you left preparation.
Can I import my existing repertoire?
Yes. Paste PGN or import your lines, and build or refine trees for both colors in the explorer. Transpositions are detected automatically so the same position shares one review card.
Stop re-learning the same openings
Build your repertoire once, and let spaced repetition keep every line sharp. Ready in a minute.
