Chess Position Evaluator

This project captures a chessboard from a screenshot, extracts its FEN (Forsyth–Edwards Notation) representation, and uses Stockfish to suggest the best move. It now includes a graphical user interface (GUI) using Tkinter.

Features

✅ Captures the chessboard image using a single click
✅ Extracts the FEN from the image via Chessify
✅ Automatically flips the board if playing as Black
✅ Uses Stockfish to suggest the best move
✅ Auto Move Execution: Automatically makes the best move in the game
✅ Graphical User Interface (GUI): A user-friendly interface instead of the terminal
🛠 New Features:
