Lichess Broadcasts Dataset

Dataset Description

931,021 chess games from chess tournaments tracked using Lichess Broadcasts.

Lichess Broadcasts show live games as they unfold with new moves arriving in real time. They are built to connect to the live-updating PGN file produced by DGT boards but can work with other sources as well.

Broadcasts are organized in "tournaments" and "rounds."
