No.746 by Aleksey Oganesjan – A nice journey of the wP and a promoted wQ! (JV)

Definitions:

Minimummer: Black must play his geometrically shortest move or may choose from among shortest 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 Pythagoras’s s theorem (take the square root of the sum of the squares of the orthogonal distances). All other orthodox chess rules apply. White Minimummer: White must make moves with minimal possible length.

White UltraSchachZwang: White must give a check on every move (otherwise White is considered in stalemate).

Unusual kind of circuit: promoted queen follows exactly “in the footsteps” of pawn backwards to initial square d2. (Author)
