Study curated lines
Courses introduce practical opening lines in an order that makes sense for a player building real-game memory.
Opening study should happen on the board.
Chessmate is a chess opening trainer for players who already play online and still feel uncertain after the first few moves.
Why we built it
Opening study often starts in the wrong place. A line can look clear in a video, book, or database, then disappear when the same position appears in a real game.
Chessmate turns that gap into a training loop. You study a curated opening line, play the important moves on the board, then review the line before it fades.
How Chessmate teaches
The app keeps opening theory close to the position, so every move has a job and every review asks for recall.
Play from the position
Chessmate asks for moves on the board, so the line becomes something you can recognize during a game.
Review before it fades
Learned lines return on a spaced schedule, keeping useful opening moves available for recall.
Expand with purpose
Start with one line, repeat it until it feels familiar, then add more branches as your repertoire grows.
Built around curated opening courses
Every course is organized around opening lines: the moves, the position reached, and the idea the line is meant to teach.
The catalog covers familiar opening families such as the Sicilian Defense, Queen's Gambit, Ruy Lopez, Italian Game, Caro-Kann, French Defense, and more. The goal is practical opening memory through lines you can train.
Editorial standards
The Chessmate team, the people who build the app, writes and maintains the guides, opening pages, and glossary on this site. We publish under the team name instead of individual bylines, so this is how that content is made.
Legal moves, checked in code
Interactive board exercises in our guides are tested with chess.js, an open-source chess rules library, so every move they ask you to play is legal.
Sources checked before publishing
Rules and opening names are checked against public references such as the FIDE Laws of Chess and the Lichess list of opening names. When a guide describes another app or book, we check its official pages first.
Dates you can see
Each guide shows when it was published and, after a substantive revision, when it was last updated. When two guides answer the same question, we merge them into one page and redirect the old address.
Our own product, disclosed
Chessmate makes the opening trainer this site describes. When a guide recommends Chessmate, read it as a recommendation from the app's maker.
