Selbstplagiat!
Gunter Jordan: Er kann es halt nicht lassen! Genau die gleiche Aufgabe veröffentlichte Pankratiev in Springaren, Heft 137, 09/2015, Nr. 13442. Kurioserweise dort mit dem Ko-Autor M. Gershinski. (2017-02-27)
Olaf Jenkner: Was hat der Erfinder von Unix damit zu tun?
Zwar hat er die ersten Endspieldatenbanken geschaffen, aber im Hilfsmattbereich ist er doch ein unbeschriebenes Blatt. (2017-02-27)
Gunter Jordan: Ich habe noch einmal in der Ursprungsquelle (SuperProblem) nachgesehen. Der Ko-Autor ist nicht Ken Thompnon, sondern Gerschinski (wie auch beim Selbstplagiat). Ich habe K. Thompson als Autor gelöscht, bekomme aber Gerschinski nicht in die Datenbank hinein, der wird so komisch geschrieben. Vielleicht kann jemand helfen? (2022-01-03)
