NNUE Chess Dataset

This dataset contains chess positions with evaluations for training NNUE (Efficiently Updatable Neural Network) chess engines.

Dataset Composition

The dataset consists of three distinct data sources, each providing different types of positions and evaluation contexts:

1. Evaluations

  • Source: Lichess Open Database
  • Method: Positions extracted from Lichess games with their corresponding engine evaluations
  • Evaluation: First principal variation (PV) line score from the original analysis
  • Purpose: Provides diverse positions from real games across various skill levels and opening types

2. Puzzles

  • Source: Lichess Open Database
  • Method: Extracts two critical positions from each puzzle:
    • Pre-mistake position (before the critical error)
    • Post-mistake position (after the critical error)
  • Evaluation: Re-analyzed using Stockfish 16 (depth 12) with tablebase support (5-man)
  • Purpose: Focuses on tactically rich positions where accurate evaluation is critical

3. Endgames

  • Source: Tablebase positions
  • Method: Sampled positions from endgame tablebases
  • Evaluation: Scored using Stockfish 16 (depth 12) with tablebase support (5-man)
  • Purpose: Ensures strong endgame understanding with theoretically perfect tablebase knowledge

Technical Specifications

Engine Configuration

Data Format

  • Position Format: Positions are stored in the fen column using a compressed FEN notation
  • Decompression: Use the decompress_fen function from dummy_chess to convert to standard FEN
  • Evaluation Format: All positions include centipawn (cp) evaluations from White's perspective, or mate-in-N scores where applicable

Tools & Dependencies

This dataset was created using the following tools:

  • dummy_chess: Used for preprocessing, PGN parsing, position extraction, and FEN compression/decompression
  • python-chess: Chess library for position handling and move generation
  • Stockfish 16: Engine for position evaluation
  • Syzygy Tablebases: Endgame tablebases for perfect endgame knowledge

Data Sources

  • Lichess Open Database - Games and evaluations
  • Lichess Puzzle Database - Tactical positions
  • Syzygy Tablebases - Endgame positions

Use Cases

This dataset is suitable for:

  • Training NNUE networks for chess engines (specifically dummy_chess)
  • Supervised learning for position evaluation
  • Testing evaluation function accuracy
  • Research in chess AI and position assessment
