## Description

SimpleChessBoard is a user-friendly chess analysis tool available as a browser extension and a web page. It allows users to load chess positions or complete games using FEN or PGN notation. Users can also manually setup and edit positions in edit mode using intuitive mouse controls.

The extension supports browsing game history, testing variations, and displays arrows indicating both the last move and the engine's recommended move. It lists all legal moves, detects checkmate or stalemate, and integrates a JavaScript version of the powerful Stockfish engine for position evaluation. An evaluation graph visualizes mistakes and blunders with color coding.

Users can share or save positions and games via URL encoding, allowing easy sharing with friends. Additionally, it offers the ability to play against the computer, flip the board, and easily navigate through moves. This versatile tool is perfect for chess players seeking quick, interactive game analysis and practice right from their browser.
