ChessBot using OpenCV and Stockfish

ChessBot is an intelligent chess-playing application that leverages OpenCV to read the screen, detect a chessboard, and interact with a chess engine (Stockfish) to play moves based on the bot's color.

Features

• Screen Reading: Uses OpenCV to capture the screen and detect the chessboard.
• Move Detection: Identifies the current state of the board and detects the opponent's moves.
• Bot Interaction: Interacts with the Stockfish chess engine to calculate and play the best move.
• Color-Based Play: Configurable to play as either white or black.

Requirements

• Python 3.x
• OpenCV
• Stockfish engine
• chess library
• numpy

Installation

1. Clone the repository:

   git clone https://github.com/sakthilkv/chessbot.git
   cd chessbot

2. Install dependencies:

   pip install opencv-python chess numpy

3. Download Stockfish: Download the Stockfish engine from the official website and place the executable in the project directory.

Usage

1. Setup and Run:

   python chessbot.py

2. Input Bot Color: When prompted, input the bot's color:

   • w for white
   • b for black

How It Works

1. Screen Reading:

   • Captures the screen using OpenCV.
   • Detects the chessboard and extracts the current state.

2. Move Detection:

   • Compares the current state with the previous state to detect moves.
   • Uses the chess library to validate moves and update the board state.

3. Bot Interaction:

   • Configures and interacts with the Stockfish engine to get the best move.
   • Plays the calculated move on the screen using OpenCV.

4. Color-Based Play:

   • The bot plays according to the specified color and waits for the opponent's move before making the next move.
