Sure, here's an example of a simple text-based chess game implemented as a single HTML file using JavaScript:
This is a very basic implementation of a chess game using pictograms (Unicode characters) displayed on a chessboard-like grid. Each piece is represented by a specific Unicode character, and the game logic allows you to click on squares to switch turns, but it does not enforce any chess rules or movements.
Please note that this is just a starting point, and if you want a fully functional chess game with AI or multiplayer capabilities, a more complex implementation is required.
