Die kürzestmögliche OR erfordert 23 schwarze Züge (C+), die Zugfolge ist nicht eindeutig.
In "32 personaggi e 1 autore" (p.533) fälschlich ohne wBb7 abgedruckt (aber mit korrekter Steinkontrolle 10+11). Die Korrektur ist nachzulesen in "La genesi delle posizioni" (p.217).
Henrik Juel: The task of changing who has the move can be accomplished in 15 black moves:
1.La7 Kb2 .. 6.Lb8 Kb7 7.La7 Kc7 8.Lb8+ Kc8 9.La7 Kb7 .. 15.La7 Ka1 16.Lb8,
or, if it is Black to move:
1... Kb2 2.La7 Ka3 .. 6.La7 Kb7 7.Lb8 Kc8 8.La7 Kc7 9.Lb8+ Kb7 .. 15.Lb8 Ka1 (2012-07-26)
Mario Richter: Since the wL can lose a tempo on b6-d8, the OR can be done even faster:
WTM: 1.La7 Sb7 2.Lb6 Kb2 3.Ld8 Ka1 4.Lc7 Sd8 5.Lb8
BTM: 1. ... Sb7 2.La7 Sd8 3.Lb6 Sb7 4.Ld8 Kb2 5.Lc7 Sd8 6.Lb8 Ka1
My guess: diagram error. (2012-07-26)
TBr: Indeed, Mario, a diagram error just in "32 personaggi e 1 autore" (p.533), where the diagram is given as here -- but with piece count 10+11!
Correction in "La genesi delle posizioni" (p.217): Add white Pawn b7. (2012-07-26)
Henrik Juel: With a white pawn added on b7, the play by black king is a1-b2-a3-a4-b5 followed by a round trip, the orientation of which depends on who has the move, like in P0005205 (2012-07-26)
A.Buchanan: For an article I am writing, does anyone have any pithy quotes by Ceriani about ortho-reconstruction, preferably in Italian, please? (2023-08-10)
