Sure, here's a simple implementation of chess as a single HTML file using JavaScript and enclosed in script tags:
Chess Game
This implementation creates an 8x8 chessboard using HTML elements. The chess pieces are represented as pictograms using the chess-pictograms library. The `initializeChessBoard()` function creates the chessboard squares, and the `placeChessPieces()` function places the pieces in their initial positions. The `startChessGame()` function initializes the board and places the pieces.
Please note that this is a very basic implementation and does not include logic for playing the game, moving pieces, or any interactivity. It simply sets up the visual representation of the chessboard and pieces.
