Your opening repertoire, built from your own games
Keep the openings you play, with your move in each position. See where each game left your repertoire, and prepare for your next opponent.
Build it your way
Start from the moves you play most in your games, change any move by hand, or import a PGN file. You keep one repertoire for White and one for Black.
Check it against your games
Each game you review shows where it left your repertoire, so you know which line to learn next.
Practise it
With Pro, practise every position of your repertoire after the moves that lead to it, and see how many of your moves you play from memory.
Prepare for an opponent
Look up a player on Lichess or Chess.com: what they play with each colour, how their games end, and how you score against their openings. Your browser downloads their public games directly, and nothing is stored.
Questions
Can I import my repertoire from a PGN file?
Yes. Import a PGN with your lines, or build the repertoire from the moves you play most in your games.
Is the repertoire free?
Building it and checking your games against it are free. Practising it position by position is part of Pro.
