How It Works

This project stores an image inside chess games by encoding its binary data into chessboard square colors.

Step-by-step explanation

1. Convert image to binary
   The image is turned into a long string of 0s and 1s (binary data).

2. Map bits to square colors

   • 0 → white square
   • 1 → black square

3. Generate moves with Lichess bots
   Two bots play against each other on Lichess.
   For each bit in the binary string:

   • If the bit is 0 → move a piece to a white square (e.g. e4, d5, etc.)
   • If the bit is 1 → move a piece to a black square

   The bots keep making legal random moves to squares of the required color.

4. Handle game endings
   If a game ends (checkmate, draw, etc.) before all bits are encoded, the bot automatically starts a new game and continues encoding.

5. Decode the image
   After all bits are stored:

   • Collect all the PGN files
   • Extract the sequence of target square colors
   • Convert back to binary (white = 0, black = 1)
   • Rebuild the original image

Purpose

Absolutely none.
Just a fun, completely pointless steganography experiment using chess.
