It's not doable to comprehend even one M&Bxx chapter in a single sitting. Most would not enjoy reading a full section of the intended reference at once.  This chapter is chosen right now because it is where Ranker and Filer are defined. CamelFiler was explained the last comment down to the detail of its exact arrival squares numbering 4 in open board. Even getting that specific may escape some individual's grasp. One reason is that involved cvers can get wrapped up in their own CVs exclusively and not follow others' work. Another, it is anyone's privilege not to care about a technical topic or discussion (the way one reads the Sports Page and another Business Page of New York Times). CamelFiler is one of 100 or 200 or more separate, specific p-ts having the sort of mode of moving aslant, or oblique, in ''wide'' directions you could say. Here ''wide'' means more files than ranks. That very definition is in this article, and the other one is Ranker moving more ranks than files -- when the x- and y-directions are separated out and tallied.
No doubt Charles Gilman's material in M&Bxxs alone, excluding the CVs, surpasses Ralph Betza's in content by a factor of 10 or even 20, comparing to Ralph/s series ''Ideal & Practical Values.''  It is Betza who makes sport of CVs as he goes, and instead Gilman takes the subject seriously. There is really no comparison at all, Betza to Gilman, partly because the content of the field has probably tripled since Betza left 10 years ago. As a result, his knowledge is a pittance compared to Charles'.________________Regarding the Ranker/Filer class, what would be the point, now that Ranker and Filer are defined, to act like some characteristic case-in-point ZebraRanker is a new p-t. It is not because it is implied, whether or not specifically mentioned by the Ranker definition. ZebraRanker moves not standard Zebra's 8, but just 4 from starting square e4 to any of g7, g1, c7, c1. That's it, specific as it is useful. You cannot declare ZebraRanker a new invention any more than 100 others strictly ranker/filer subgroup, but please invent new CVs utilizing them one and all.________________________________The other Chapter linked, or commented  yesterday rather, is Number 16 ''Diverging Further'' this same groundbreaking series. That 'M&B16' continues naming and defining divergent piece-types, that move and capture differently.  The classic examples are Western Pawn and Eastern Cannon(M&B02).  Of the 100 suffixes applying to rectangles of squares, 20 or 30 will be found to carry divergency weight.
