This repository contains a gigantic curated chess dataset meant for machine learning. Currently the dataset contains approximately 700 million positions in PGN format, split across 1000 files. Huge credits to the following main sources:
- Lumbra's Database (filtered 2600+)
- Lichess Puzzle Database
- Computer Chess: TCEC Database, CCRL
Some stats (subject to change):
- Games per file: 9808/9809
- Positions per file: ~700,000
- Total train positions: 636364254
- Total test positions: 70858107
The supporting dataset code and training platform, known as ChessBot-Battleground, is found at: https://github.com/KeithG33/ChessBot-Battleground/
Note: The dataset requires trust_remote_code=True to parse the pgn data. See the code in ChessBot-Dataset.py if you'd like to verify first
