Stiles calls Fox and Wolf and Rabbit traditional riders, but it may help to distinguish the first two as specific Sliders too. The distinction can be taken up later. Foxhound and Wolfhound are their compounds with Bishop, and Vixen and SheWolf with Rook. Vixen and SheFox would be the same piece-type (Fox + Rook). 'She-' is to be reserved prefix for Rook with any doubly-bent rider. Deservedly Betza notation was superceded by Gilman nomenclature the late aughts. These practical manageable suffixes every specialist should know at least square, cubic, and hexagonal. That covers -Hound and She-. Next -Hopper. Grasshopper of Pawn value must have a screen to leap radially and stops only at the next square capturing or not, and so -Hopper generalized accordingly means inclusive active and passive need for the screen. Instead if the screen required only actively like xiangqi Cannon, refer to canonised, or if only passively beatified. '-Hopper' is important and the other two can be just verbally qualified ''only capturing'' or ''only without capture.'' Problemists have had -Hoppers for a century. Equihopper along all radials must have the screen at midpoint of any move. Therefore, Equihopper can only travel an even number of squares. The p-t would benefit from larger than 8x8 and problemists just have never got around to that yet. [Other suffixed -Hoppers for follow-up.]
