Chess Game Engine

A Python-based chess game engine with a graphical interface using Pygame. This engine includes functionalities to manage the game state, validate moves, log moves, handle AI for making moves, and provide a visual interface for playing chess. The project utilizes numpy for efficient array operations.

This project was inspired by Mittens, the strongest chess bot released by Chess.com.

Features

• Comprehensive Game State Management: Tracks the board state, player turns, and special conditions like check, checkmate, and stalemate.
• Move Validation: Validates all possible moves, including special moves like castling, en passant, and pawn promotion.
• Move Logging: Maintains a log of all moves made during the game, enabling undo functionality.
• AI Integration: Uses negamax search with alpha-beta pruning to determine the best moves for the AI.
• Graphical Interface: Utilizes Pygame for a visual representation of the chessboard, handling user inputs and displaying the game state.
• Efficient Array Operations: Utilizes numpy for handling the chessboard as an 8x8 array for efficient computation.

Installation

To use this chess engine, clone the repository and install the required dependencies.

git clone https://github.com/yourusername/chess-game-engine.git
cd chess-game-engine
pip install pygame 

Project Structure

• main.py: The main driver file for handling user input and displaying the game state using Pygame.
• ChessEngine.py: Contains the GameState class that manages the current state of the chess game and the logic for making moves.
• ChessAI.py: Contains the AI logic for determining the best moves using negamax search with alpha-beta pruning.
• images/: Directory containing images for the chess pieces.
