Sure! Here's a simple example of a chess game implemented as a single HTML file using JavaScript:
In the above code, the chessboard is represented by a 2D array `board` containing the Unicode characters for the different chess pieces. Each square on the board is represented by a `<div>` element with a class of `square`, and an `onclick` event handler is added to each square to call the `move()` function.
The `move()` function is a placeholder to handle the move logic for the game. You can implement the game rules, piece movements, capturing, etc. in this function using JavaScript.
Note: This is just a basic example to get you started. To create a fully functional chess game, you would need to implement the complete set of chess rules, handle turn-based play, validate moves, check for checkmate, etc.
