Export your chess games from lichess.org

Requires only Python (2 or 3) and requests with gevent:

pip install grequests

Also, on Linux if you want to export to Scid you need to install Scid: sudo apt-get install scid.

Example:

python lichess.py -n hippo23 -t pgn -o hippo23.pgn  --threads 6

If you want scid base: python lichess.py -n hippo23 -t scid -o hippo23 --threads 6

If you have more than 1000 games, you can set threads more than 3. If you have more than 10000 games, set threads to 10
