Web application focused on blindfold chess training. It provides tactics and games to improve yourboard visualization.

All tactics puzzles are imported fromlichess.

The application is available athttps://blindtactics.com

• Games
  • Tactics where you'll have to mentally follow a series of moves before solving the position.
  • Given a position without a board, find all the possible checks.
  • Enumerate all the shortest knight paths between two squares.
  • Given a set of pieces find the squares that are attacked by all.

With more to come!

The application consists of the single-page frontend app and the backend server.

You'll need nodejs and yarn/npm installed.

cd uiyarn installyarn run bundle

The static files will be located atui/dist.

You'll need rustc and cargo installed. Both can be installed throughrustup.

cargo build --release

The binary can be found at./target/release/server.

Now we can start the server and make it load the frontend application with thefollowing command:

./target/release/server -s ./ui/dist

Note that you'll also need to provide the necessary environment variables (foundindocker-compose.yml) to establish connectivity with the postgres database.

Alternatively you can use the pre-built docker image (mujx/blind:latest) withthe docker-compose file to spin up the whole system.

docker-compose up

The app will be available athttp://localhost:9999

⚠️ At the current stage, the SQL schema and the puzzle import will have tobe done manually.

1. Download the csv file from the puzzlespage.
2. Use the server cli arguments to load them to the database

./server --puzzles-file puzzles.csv

3. You can re-run the above command to refresh your puzzle database.
