Mirko Degenkolbe: Wenn man auf den Käfig verzichtet (der Schlüssel spielt sich ja quasi "von selbst"), kann man den Inhalt auf das Miniaturformat herunterbrechen:
Kc4, Bb6
Ka4, Lc1, Ba3, Ba5, Bc7.
#5
In diesem weißen Minimal gibt es jetzt eine zusätzliche Verführung und ein zusätzliches Matt im Lösungsspiel.
Außerdem ist der Mattdual aus der Originalversion nicht mehr vorhanden. (2020-10-03)
Kurt Keller: Ein interessantes Problem ohne den Käfig zum Vergleich! Das Minimal enthält nicht mehr "Verführungen" als das Käfigproblem. Die einzige "Verführung" des Minimals scheitert an 6! Verteidigungszügen. Das zusätzliche Matt ist nur vierzügig. Das Ende der vollzügigen Lösung beider Probleme ist gleich. Sieht man von der Teilparade jeweils ab, gibt es keinen Mattdual. (2020-10-04)

Happy Holidays
By Mike Prcic

As the holiday season approaches, we are reminded of the current COVID-19 pandemic. It has been a difficult time for many of us. I have been in touch with many composers. Many are suffering, especially the older ones. Some are not infected but still need medical care, which is not available, since the hospitals are swamped with COVID-19 patients. One of StrateGems’ editors lost his younger brother to COVID-19. A long-time subscriber from Italy informed me that his whole family was infected. He had the hardest time with the infection but survived and is now COVID-19 negative.
On a positive side (if there is such a thing), we all have ample time for composing (and in my case for playing online bridge). WCCT-11 should benefit from the pandemic. Nevertheless, I hope the vaccine arrives soon, is effective, and that we all can go back to our lives.
To brighten the holiday spirit, Kurt Keller has sent a composition that reminds us of the Christmas tree. Thank you, Kurt!
