Definition: (click to show/hide)
Maximummer: Black must play the geometrically longest move or may choose from among longest moves of equal length, distances being measured from the center of each square. Diagonal and oblique distances are measured from the orthogonal coordinates by using Pythagora’s theorem (take the square root of the sum of the squares of the orthogonal distances). All other orthodox chess rules apply.

Why so strong a key cutting out the current longest move?
It is possible to improve (I think) the key and simultaneously remove at least four pieces…
I agree. Only reason could be that the author wanted the key also to open & close lines!
