Sure! Here's a simple implementation of a chess game using JavaScript that can be played as a finished game and is suitable for smartphone operation. The game will be displayed using UTF-8 characters to represent the chess pieces.

Chess Game

This HTML file contains JavaScript code enclosed within `
` tags. It represents the chessboard using a multidimensional array and displays it using an HTML ``. The chess pieces are represented using UTF-8 characters for pictograms. The `startGame()` function can be expanded to handle user input and implement the game logic.
