This bot posts puzzles that are randomly selected from the open-source Lichess puzzle database. The caption of each puzzle provides information, along with a direct link.

Images are generated with the help of the chess.cvg library, from parsing FEN.

Since the file size of ‘lichess_puzzles.csv’ is too large to upload (>300mb), I’ve uploaded ‘reduced_lichess_puzzles.csv’ instead. This file contains the first 10,000 puzzles.

• Automate posting, at regular intervals.
• Periodically select puzzles from higher-rated games, or titled players.
• Automatically comment the tweet with the solution, after some period of time.
