Meredith. White minimal. Model mate.
Very precise rooks’ maneuvers without captures:
“Snaky staircase” of wR: Rg8-b8-b7-f7-f5-b5-b3-g3
“Snaky staircase” of bR: Rh7-a7-a5-g5-g3-a3-a1-h1
The maneuver “Snaky staircase” is a hybrid of a “snake” and a “staircase” :)

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.

In addition to "snaky staircase", author can propose another names of this maneuver: for example, "orthogonal snake" or "harmonica" ("accordion", "garmon") :-)
