Problem 511: Aleksey Oganesjan - Fairy (Maximummer)
aleksey.oganesyan(26.01.2015) Fairy selfmate Maximummer by Aleksey Oganesjan with nice maneuvers by both Rooks.
1.Rb8! Ra7 2.Rb7 Ra5 3.Rf7! Rg5 4.Rf5 Rg3 5.Rb5! Ra3 6.Rb3 Ra1 7.Rg3! Rh1#
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") :-)

Snaky staircase seems an apt name !
