Hilmar Ebert

→ 2977. Die Schwalbe XII 1979

→ 1^st Prize „Wenigsteiner des Jahres“ 1979.

h#5 → Rex Multiplex

h2 = Royal Pawn, b2, f2 = Royal Equihoppers

1. h1=N? is insufficient, as is easily seen…
1. h1=E?! forces a draw!  (1... Kd1 2. E-d3 Kd2+ 3. E-h1 … etc.)
1. h1=R!! Kd3  2. Rh7!! Ke4  3. E-h6 Kf5  4. E-f8 Kf6  5. Rh8 Kg7#

 „Horizontal symmetry in the initial position is transformed into diagonal symmetry in the finale. Note tempo move by black royal rook.”.

A fairy promotion trap and orthodox promotion key, combined with a symmetry switch (linear ↔ square form). Also present is a logical choice with purity of aim in White’s second move: Compared to 2. Rh8?, only 2. Rh7! achieves the tempo gain required for perfect timing!  “A kind of sadistic humor aimed at the poor solver, who, adrift on the open ocean, must discover the inconspicuous square h7 as the single saving island.” (h.e.).
