A hand-drawn chessboard fills the panel, with light and dark squares, and a game in progress. The board is broken into sliding-puzzle tiles, one tile being 2x2 chess tiles, resulting in 4x4-1=15 sliding tiles. One tile with a white pawn and a white knight on it is sliding from position 3/3 to position 4/3. A caption on the bottom reads "Sliding Number Puzzle Chess".Hidden text: "The draw-by-repetition rule does a good job of keeping players from sliding a tile back and forth repeatedly, but the tiles definitely introduce some weird en passant and castling edge cases."</a></label><br><a href="https://media.mastodon.com.br/media_attachments/files/115/170/863/003/379/845/original/d3897656b273f779.png" rel="external">https://media.mastodon.com.br/media_attachments/files/115/170/863/003/379/845/original/d3897656b273f779.png</a></li></ol></footer></blockquote>
