| 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. |
