The puzzles are excellent but they do have an annoying 'feature' in marking down an alternative checkmate move.
Eg. Puzzle #1572314, checkmate can be delivered by the queen (the puzzles preferred answer) or by the rook, as the defending Bishop is pinned. I chose the rook, and lost points (not a tragedy I know), but it is irritating.
Checkmate is checkmate, regardless of how it is delivered.
The king can capture the rook. There's only one solution
