Henrik Juel: The Larsen author is Kjeld Larsen, not KAK Larsen (2021-03-29)
James Malcom: Fixed. (2021-03-29)
A.Buchanan: Henrik: I love these many-handed accomplishments: please can you tell us more about the creative process whereby 7 composers collaborated on the arrangement of just 5 pieces? (2021-03-30)
Henrik Juel: I only saw your comment today, Andrew
Most of these small problems with many authors came about as a result of a sort of theme tourney, and that is also the case here
The TD editor, Holger Helledie, posed several construction exercises with very short deadlines
Here he asked for a helpmate problem with two black S promotions and minimal force
The theoretical minimal force would be KP-KPP, but nobody submitted this
The second best is KS-KPP, and six participants indepently found this problem
Holger had found it himself, so he is included as author
The winner of this exercise was the strong finnish composer, Unto Heinonen, with KL-KPP (2021-04-25)
Henrik Juel: Unto's problem was P0504865 (2021-04-25)
A.Buchanan: Thank you for the details. So the mental picture I had was incorrect: a troupe of composers muttering around a single chessboard, irascibly nudging a smaller number of pieces from square to square. (2021-04-25)
