# Lichess Broadcasts Dataset
## Dataset Description
931,021 chess games from chess tournaments tracked using [Lichess Broadcasts](https://lichess.org/broadcast/help).
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."
