Mustermatt 239: Wie entwickelt man eine Problemidee?

"Mustermatt" is the video channel of "Schwalbe," the German Association for Problem Chess. In these videos, we want to introduce chess problems and show you: how to solve chess problems? what topics are there in problem chess? who were/are the authors of problems? and much more. New videos are released every Friday. This time, I'll show you the origin story of a selfmate.
