This is a simple implementation of a chess game using HTML, JavaScript, and pictograms. The code defines the Chess object that handles the game logic. It initializes the chessboard, draws the board on the canvas, and listens for mouse clicks to select and move pieces on the board. The code represents the chess pieces using pictograms (e.g., "♔" for white king, "♛" for black queen, etc.). The game starts when the HTML file is opened in a web browser and players can interact with it using a smartphone.
