Die beiden Autoren machten den Vorschlag, unter das Diagramm das aus dem orthodoxen Bereich bekannte "v" zu setzen. Dies widerstrebte mir dann doch. Ein diesbezüglicher Hinweis im Vorspann mußte genügen.
Autoren: Rehm-Thema, diagonal und orthogonal mit eindeutigen thematischen Verführungen durch den jeweils "falschen" Hinterstein.
AB: Sehr leicht zu durchschauendes Peri-Manöver.
Schwarz-weiße Opferbahnungen nach einleitenden Umschiffungen des jeweiligen wWirkungssteins (HJ).

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)

A.Buchanan: Please forgive me but I think “under-promotion” is only meaningful for directmates and studies. That’s why I had put in promotion as a keyword, not under-promotion. In helpmates, promotions need to be distinguished of course, and we can put in the officer type in the parameter slot. Under-promotion would still need such a parameter because it’s inexact itself: the worst of all worlds. Even for directmates and studies of course some people consider knight promotion not to be an under-promotion at all, but I wouldn’t go that far myself. There are far too many keywords covering promotion, and at some time we should clean them up, but in the mean time I am open to considering another opinion if it is explained to me. Thank you.
