Dieter Berlin: Über den Dual kann man lt. Lösungsbesprechung Febr.1981 geteilter Meinung sein: Ich zähle den Zug
1. ... Sd6 zu S~, und Dr. Dragone wies darauf hin, dass S~ so behandelt wird, als sei der S vom
Brett verschwunden (die Briten sagen dazu "random move"), und dann geht nur Ld:. Diese Frage ist bis heute nicht geklärt, denke ich. (2021-02-10)

A.Buchanan: Can someone document the keywords Dual Avoidance and the opaque Theme B2, please? (2023-04-08)
Henrik Juel: Dual avoidance is best explained by looking at this problem
1... Sf4 blocks f4, so White can interfere Lb8 by 2.Te5,Sd6, apparently; but !... Sf4 also opens for Df1, so Sb5 is pinned, and the dual is avoided
B2 is one of many terms invented by Barulin & Issaev in 1922; it means block-interference, e.g., 1... f4 blocks f4, allowing 2.Sd6# to interfere Lb8; it is no longer considered a theme, because it is such a simple device
I think that 'Theme B2' should be deleted as a Keyword; it is just another one of the terms making it more difficult for beginners to read chess problem literature; the important stuff is understanding basic concepts like block, interference, and pinning (2023-04-09)
