Chess Tournaments Analyzed with Stockfish
This dataset contains the larger files. To download the dataset with smaller files for e.g. ongoing super tournaments, see https://github.com/drmehmetismail/Chess-Tournaments-Stats-Database

To replicate and calculate game intelligence (GI) score, missed points, and many other metrics, use the scripts at

1 missed point = making a losing blunder in a winning position. 0.5 missed points = making a losing blunder in a drawn position, or drawing blunder in a winning position. 0 missed points = perfect play.

## Sesse
Special thanks go to Steinar (https://sesse.net/), the owner of the well-known chess computer Sesse, who kindly agreed to share with me detailed raw data for all analyzed moves up to and including December 31, 2024. Under the 'Sesse' folder, I have merged this data into a more user-friendly PGN format. An analysis of these games can be found in the same folder.

Sesse_PV.zip in the Sesse-as-of-31-Dec-2024 folder contains all games and moves analyzed by Sesse. The PGNs also include the principal variation (PV) provided by Sesse.

To download all games with all variations, including PV and refutation lines, download 
All_games_all_lines.tar.zst

Use your favorite chess GUI to import these games and explore the variations. 
Note: Each game file may become significantly large in this case.
