Sure! Here's a simple implementation of a chess game in a single HTML file using JavaScript. This version allows each player to make 2 moves per turn, and it's designed to be playable on a smartphone. The chessboard will be displayed using pictograms for each piece.
Please note that this is a simplified version and does not include all the rules and complexities of a complete chess game. It's just meant to provide a basic starting point.
Chess Game
To play the game, simply open this HTML file in a browser on your smartphone and follow the prompts to enter your moves. The current state of the chessboard will be displayed, and after making a move, the updated board will be shown.
Please note that you'll need to implement move validation and the logic for handling the rules of chess (such as checking for checkmate or stalemate) to create a fully functional chess game. This basic implementation provides a starting point for further development.
