Chessboard UI with Move History

Move History

 

Features Explained

1. Coordinate Mapping: The logic uses String.fromCharCode(97 + c) to convert column indices (0-7) into board letters (a-h). This is essential for standard chess notation.

2. Stateful Interaction: The script tracks whether a square is currently "selected." If a second square is clicked while one is selected, it executes a movePiece function, which handles the DOM swap.

3. Unicode Graphics: Instead of loading 12 different image files for pieces, we use high-fidelity Chess Unicode characters. These scale perfectly without losing quality.

4. Responsive Design: The board size uses min(80vw, 500px), ensuring it never grows too large for the screen or too small to be playable on a phone.

How to use this tool:

• Select: Click any piece to highlight it.

• Move: Click a destination square to move the piece.

• History: Watch the panel on the right (or bottom on mobile) to see your move log.
