Wa Shogi's Heavenly Horse is not only a Nightranker, it is the Nightranker. To grasp ''Nightblinker is Nightranker capturing as a Nightfiler,'' there are already two more Suffixes assumed, Ranker and Filer. The subclass Ranker requires moves covering more ranks than files, and Filer more files than ranks. In themselves they are non-divergent, meaning capture and non-capture modes alike. They are intended for oblique directional piece-types, but separating x- and y-axes for the lengths. Outwards that includes Knight, Camel, Zebra, and then the rest of them up to 11 or 12 spaces so far defined. Restricting Knight to half his directions is Nighrranker, the Heavenly Horse (value 2.0); and Nightfiler too has only 4-squares potential from a starting square all different from Nightranker's four. A couple of earlier chapters are mostly divergent p-t naming, like M&B16 -- which refers back to the others, M&B06 M&B10. There in M&B16 is found the divergent Nightblinker of the introductory sentence among the Blinkers. Also for follow-up is Contrablinker as well as facility just going back and forth and expanding among all these Right-, Left-, and Contra-blinker, Ranker and Filer -- the same way done recently among related Scout, Dueller, and Guide -- with specific made-up piece-types. For one, CamelFiler from a starting square e4 travels, presumably leaping and not more interesting multi-path, to any and only a3, a5, h3, h5.________________________________________ CamelFiler is more restricted even than mediaeval Alfil, who reaches 1/4 the 64-square board. CamelFiler starting at a1 can only access a1, a3, a5, a7, d8, d6, d4, d2, g7, g5, g3, g1. //// The possibilities can hardly get exhausted. I don't think Charles mentions a NightrankerBlinker who reaches four squares from any given departure square, only two of which are non-capturing (value 1.25).
