Chess Engine v1.0.0

First public release of Chess Engine, a Java chess engine built around persistent graph exploration, exact endgame solving, and an interactive Swing analysis interface.

Highlights

  • Persistent canonical PositionGraph with transposition reuse
  • Dovetail and Hybrid search modes
  • Strength-aware stochastic exploration
  • Full legal chess rules:
    • castling
    • en passant
    • promotion
    • checkmate and stalemate
    • repetition and move-count draw handling
  • Interactive analysis with continuation navigation
  • Custom position setup and FEN support
  • Optional Stockfish 18 comparison mode
  • Exact three-piece endgames:
    • KQK
    • KRK
    • KPK
  • Complete 30-family canonical four-piece tablebase catalog
  • En-passant-aware KP-KP tablebase
  • Interactive endgame curriculum and practice mode

Download

Download:

Chess-Engine-v1.0.0.zip

The package includes:

Chess-Engine-v1.0.0.jar
tablebases/
stockfish/
    PUT-STOCKFISH-HERE.txt

All supported exact endgame tablebases are already included.

No separate tablebase download or installation is required.

Requirements

  • Windows
  • JDK 26
  • Stockfish 18 is optional

Running the Application

After extracting the ZIP, double-click:

Chess-Engine-v1.0.0.jar

The application automatically detects and uses the included tablebases/ directory.

Exact Endgame Support

The download includes all exact endgame data supported by v1.0.0:

  • KQK
  • KRK
  • KPK
  • all 30 canonical four-piece tablebase families
  • en-passant-aware KP-KP support

No additional tablebase installation is required.

Stockfish

Stockfish 18 is optional.

Chess Engine works without Stockfish. Stockfish is only required for the optional reference-engine comparison and continuation-analysis features.

To enable Stockfish:

  1. Download Stockfish 18 from the official website:

    https://stockfishchess.org/download/

  2. Extract the Stockfish download.

  3. Locate the Stockfish .exe file.

  4. Copy that .exe into the included:

    stockfish/

    folder.

  5. Double-click:

    Chess-Engine-v1.0.0.jar

Chess Engine will automatically detect the Stockfish executable.

No PowerShell configuration or environment-variable setup is required.

Verification

The v1.0 release passed the full release regression suite and standalone package verification, including:

  • core chess rules, graph behavior, and FEN handling
  • frozen Dovetail search verification
  • frozen Hybrid search verification
  • three-piece exact tablebases
  • all 30 four-piece tablebase families
  • endgame move controller and practice strength
  • Stockfish process and forced-mate smoke testing
  • packed KP-KP runtime under a 128 MiB heap
  • clean Maven build
  • clean-clone JAR launch
  • standalone release tablebase loading
  • packaged endgame-mode testing
  • final GUI smoke testing

Scope

v1.0 focuses on persistent graph-based search, exact small-material endgames, analysis tooling, and experimentation with nontraditional search scheduling.

The native search is not intended to replace conventional state-of-the-art alpha-beta chess engines in raw playing strength.

Five-piece and larger tablebases are outside the scope of v1.0 and are planned for future development.
