'DAZ'-Lösetip: "D- und T-Züge [führen] nicht zum Ziele. Ein K-Zug - es käme nur Kxg7 in Frage - würde an der Stellung nichts ändern; bleibt also nur 1. f7-f8. Aber was wird der Bauer? Eine D würde den Schwarzen patt setzen; T u. S. lassen den K nach d6 entweichen, also 1. f7-f8=L. Dadurch wird dem K das Feld d6 genommen und Te8 preisgegeben. ... Mit dem Bauern in die Dame zu gehen, ist nicht immer der stärkste Zug."

Der Preisbericht erschien in Gaudium 260, 10/06/2022.

PR: "Die beiden reziproken Unterverwandlungen werden mit Hilfe von mehreren Batterien realisiert, die zunächst aufgebaut und danach abgefeuert werden. Dabei legt der schwarze König in beiden Varianten einen weiten Weg zurück, bis er die passende Position erreicht hat. Der Materialeinsatz ist sehr sparsam, wobei der wLg6 für meinen Geschmack dennoch etwas unterbeschäftigt ist. "
