description: >
"The dataset contains games from the Lichess.org open database converted from
PGN format to UCI format. It is divided into two main configurations: `moves`
and `headers`. The `moves` configuration includes a UUID called `site` and the
UCI moves in a column called `transcript`, while the `headers` configuration
includes metadata such as player ELO ratings, game outcome, and dates. The
data is subset based on the year and month (yyyymm format)."

"The Lichess.org database has been converted to UCI format, making it
easier to analyze and interpret chess games. The `moves` configuration
captures the sequence of moves using UCI notation, and the `headers`
configuration provides comprehensive metadata for each game, enabling
detailed statistical and strategic analysis."
- name: headers
description: >
"This configuration includes detailed metadata for each game, providing
insights into player statistics, game outcomes, and other relevant data
points. Each game is identified by a unique `site` UUID that maps to the
moves in the `moves` configuration."
dataset_split:
- name: 201301
description: >
"The dataset is split based on the year and month of the games. Each split
includes all games played in a specific month, allowing for temporal
analysis and tracking changes in player performance and strategies over
time."
