check the source name
Henrik Juel: The source name is fine, except that the city of Elsinore is spelled with the danish/norwegian vowel ø:
Helsingør
The stuff in front of Helsingør Skakklub (Elsinore Chess Club) is probably:
Jubilæumsskrift 70 år (using the two remaining special vowels) (2023-08-06)
A.Buchanan: Hi Henrik no it's a different Jubilee: this is a Mongolian composer celebrating the anniversary of the October 1917 revolution. I added it to Sources, but forgot to update the problem itself. As far as the Elsinore version is concerned, I will try to add a Unicode version. It's still convenient to have an accent-free version of the name in order to facilitate search (2023-08-07)
A.Buchanan: I could easily have confused Helsingør (scene of Hamlet) with Helsinki (not scene of Hamlet). (2023-08-07)
Henrik Juel: Thanks for clearing up the source mess, Andrew
I did wonder why a mongolian composer would participate in an obscure danish tourney (2023-08-07)

Published in the article by Sébastien Luce: "Le charme du Scarabée", Phénix 338/2023, p.13164-13168 with a comment: "Cinq Scarabées au minimum sont nécessaires pour mater un Roi seul. Le S15 est un nouveau quadruple écho étonnant de Václav."

Beetle (scarabée) was invented in 1970 by the French composer Roméo Bédoni. Only WinChloe is able to test such problems (not implemented in Popeye either in Alybadix).
Henrik Juel: From the Schwalbe Märchenschachlexikon
Skarabäus: Ähnlich dem geknickten Grashüpfer, nur macht der Skarabäus hinter dem Sprungbock einen 1:2-Sprung in ähnlicher Richtung wie er auf den Sprungbock hinzieht. Von a1 mit Sprungbock auf d4, erreicht er e6 und f5; von d1 mit Sprungbock auf d4, erreicht er c6 und e6. (2024-01-03)
