Sorry, I am on mobile and didn’t get the puzzle ID. The puzzle starts out with White Rook moving from C8 to D8. It doesn’t show what Black’s move was before this move and it doesn’t matter as it would have been an illegal move. Why? It should be obvious.
If there was a black piece moved to or on d8 it wouldn't have been illegal
