Openings, from your own games
How Luftchess trains the openings you actually play.
Where your games left your preparation
Most opening study starts from a book. Luftchess starts from your games. It finds the positions where a game left the lines you prepared, or where an opponent played something you had not met. That is where an opening is really decided at your board.
The opening quiz: repeat the what, understand the why
The quiz shows one of those positions and asks for your move. After every try, the engine’s answer appears with the plan behind it in one short sentence: the pawn break to aim for, or the piece that wants a better square. Remembering the move is half of it; knowing why is the other half.
Each position comes back just before you would forget it, on a spaced-repetition schedule (FSRS). A position you know well comes back rarely. One that keeps slipping comes back sooner.
Repetitio est mater studiorum.
A worked example
| Move | White | Black |
|---|---|---|
| 1 | e4 | c5 |
| 2 | Nf3 | e6 |
| 3 | d4 | cxd4 |
| 4 | Nxd4 | Nc6 |
| 5 | Nc3 | a6 |
| 6 | Be2 | Your move |
Say your games as Black keep reaching this Taimanov position. The quiz shows it and asks for your move.
Play 6…Bb4 and the answer comes back: 7.Nxc6 bxc6 8.Qd4 hits the bishop and g7 at once. The engine prefers 6…Qc7: develop the queen, and keep the bishop at home for now. 6…d6 is also sound.

Then, in your games
The positions in the quiz come from openings met in real games, not from a book chosen for you. Today they are gathered from the player’s games in a separate step, now and then; bringing in new positions on their own as games arrive is still being built.
