blind.tactics

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

All tactics puzzles are imported from lichess.

The application is available at https://blindtactics.com

Features

• 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!

Build

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

Frontend

You'll need nodejs and yarn/npm installed.

cd ui

yarn install
yarn run bundle

The static files will be located at ui/dist.

Server

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

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 the following command:

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

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

Docker

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

docker-compose up

The app will be available at http://localhost:9999

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

Import lichess puzzles

1. Download the csv file from the puzzles page.
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.
