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. "
