Sorry, no updates since 2023!
In short, composing endgame studies is a discipline with very few generally accepted rules. Even the very best composers often disagree about good studies. Each judge uses their own rules. So you have to adapt. Here a some lists of completed tournaments with their judges.
The names of the judges are written with English letters only for better searches.
(Some judges are unknown. If you can fill such a gap, please contact me.)
