pretty_name: Lichess Games With Stockfish Analysis

Condensed Lichess Database

This dataset is a condensed version of the Lichess database. It only includes games for which Stockfish evaluations were available, and it does not include game headers. The resulting files are much smaller and faster to parse.

Data Format

Every position of every game either has a Stockfish evaluation or an outcome condition that is either checkmate, stalemate or insufficient material. All other outcome conditions have been excluded from the data. In the FEN dataset, the starting positions (no player made a move yet) have been excluded.

WIP

Note, the dataset is not complete yet and subject to change.
