This repository contains a gigantic curated chess dataset meant for machine learning. Currently the dataset contains approximately 2 billion positions in PGN format. Huge credits to the following main sources:

  • Lumbra's Database (filtered 2600+)
  • Lichess Puzzle Database
  • Computer Chess: TCEC Database, CCRL, LC0 training data (test80)

The supporting dataset code and training platform, known as ChessBot-Battleground, is found at: https://github.com/KeithG33/ChessBot-Battleground/

Note: The dataset uses a custom loading script (ChessBot-Dataset.py) to parse PGN data on the fly.
