As I mentioned in my Notes, the "Half-Rose" used in H. G. Muller's Interactive Diagram was chosen to be noticeably weaker than the "six-leaping Rose" used in Charles Gilman's Irwell and Wey.
For example, the "Half-Rose" on e9 does not give check here, because the Black King is located five Knight-leaps away. This is true whether you move clockwise along the blue dots or move counter-clockwise along the yellow dots. The Rose does manage to pin the Nightrider against its King.
