Schwarz hat keinen letzten Zug!

A.Buchanan: Werner opened my eyes to the delights of these “official jokes” sanctioned by Codex Article 15 through his book Eigenartige Schachprobleme. The animation does not handle them well, as the move numbering and the ordering has to be distorted as here (2021-03-04)
A.Buchanan: I expect that Werner will be delighted with this one, as it has very clean solutions and retro try, which is his aim. (2021-03-04)

b) Drehung um 90°

a) 1. Sf7+! Kxg6 2. Ld3#
b) Mit Drehung recht:
nicht 1. Sb6+? Kxc7 2. Lf4#
sondern b) 1. ... Kxc7! Lf4+ 2. Kc8 Sb6#
play all

Absichtlich wird nicht angegeben, in welche Richtung gedreht werden soll. Wenn man die Stellung um 90° im Uhrzeigersinn dreht (wKf4), gibt es keine zweizügige Lösung. Wenn man sie um 90° gegen die Uhr dreht (wKc5), entsteht eine Stellung, in der Schwarz nicht zuletzt gezogen haben kann.
Der Bauer ist entscheidend.
It is intentionally not specified in which direction to rotate. If you turn the position 90° clockwise (wKf4), there is no two-move solution. If you turn it 90° counterclockwise (wKc5), you get a position where Black cannot have moved last.
The pawn is decisive.

A.Buchanan: There are literally hundreds of problems in PDB where "Drehung um 90 Grad" means clockwise. So reading the text here, one thinks: "Oh the stipulation is wrong - I'll correct it." The joke is so slight against the noise that it's not worth bothering with. Better to have "which way?" in the stipulation. (2022-02-10)
A.Buchanan: Also the fourth orientation unmentioned has no solution. Somehow would be nice to make reference to that "for symmetry". Maybe publish the board with unshaded squares in a diamond orientation, and ask the solver to find the two orientations that work. (2022-02-10)
