Sure! Here's a simple implementation of chess as a single HTML file using JavaScript:

♜	♞	♝	♛	♚	♝	♞	♜
♟	♟	♟	♟	♟	♟	♟	♟
♙	♙	♙	♙	♙	♙	♙	♙
♖	♘	♗	♕	♔	♗	♘	♖

In this implementation, each chess piece is represented by a pictogram from the Unicode character set within the table cells. You can directly run this code in a browser to play the game.
