Comments/Ratings for a Single Item

This is the only ID where the ID seems to undervalue Rose. Other IDs assign Rose at higher values.

This is probably because it is not really a Rose (which can make up to 7 Knight jumps), but a Half-Rose, which can only do up to 4. I suppose the other Diagrams you refer to use genuine Roses.

This is a late reply ... the bent riders that are not bent are in fact long known, problemists call them slip pieces (slip-R, slip-B, and slip-Q). The slip-R is also known under the name Panda and plays with this name in the S(w)eeping Switchers army for CwDA (2002).

4-Knight-Jumps Rose shouldn't be half a ♟️ weaker than 6-Knight-Jumps Rose. They should be as close as B5 is to B.

Charles Gilman explored those pieces and assigned some more names in the game "Commedia dell'Arte Chess"

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.
