Context

This repository contains all of World Champion Magnus Carlsen' online games played on the Lichess chess server between 2017 and 2021. The files were extracted using the Lichess API, and then processed using a python library called pgn2data. This is a library I wrote, that converts PGN (Portable Game Notation) formatted files into CSV tabulated datasets. The library also adds a number of additional descriptive features to each output, to give more insight into what happened in each game.

Magnus has used a number of different user names over the past few years, so this data provides a consolidated view of all of his performance during the time he has been on the platform.

Content

There are two files:

• The file "carlsen games" contains all of the top level information for each game (e.g result, score,location, date, time etc..).

• The file "carlsen game moves" contains all the moves for each game (e.g move number, piece, location etc..).

The two files are mapped together using the unique identifer "game_id".

The original PGN files from Lichess are also included in this data repository. There is also an additional file (eco codes) to identify the openings listed in the games file.
