pretty_name: Lichess Games With Stockfish Analysis
---
# WIP
The dataset will be released in the following few days.

# 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 have been excluded (no player made a move yet).
