In Polypiece chesses, something happens and some piece-types change their move definition. Fourriere made Pocket Polypiece after Betza's idea: Both articles tend to change one-piece type at a time upon moving any one unit of the type, but Fourriere's goes further in changing them both ways, back and forth in fixed one-to-one correspondence. This is the first direct comment here in 7 years to the day +/- 5.  Revenge of the King below is different that capture of Queen, or return of Queen, changes one type's, the King's, move definition. There is a lot of unexplored territory and always will be -- Jaguaribe's world change.
Among a dozen other designers elsewhere, I did some CVs at ''91.5 Trillion CVs'' where movement rules or capture rules mutate whilst certain conditions hold:,, in which Rules Number 31 and 32 are Acid-Base and Strong Acid-Base.
