Diese Version wurde im Rahmen der Lösungsbesprechung in Gaudium 177 (05/2017), S. 3 veröffentlicht. BK ging es dabei um Folgendes: "Die Idee der 4-fachen Selbstverstellung ist nicht neu, aber interessant dargestellt. Mich stört, dass 3.Sf5 nicht zweckrein ist, da 3.Sc6? sowieso nicht geht. Unter Verzicht der aristokratischen Stellung sähe meine Version so aus."
