user11326: I'm trying to look through some puzzles at http://www.wenigsteiner.de/, but there are some abbreviations I'm not familiar with that I'm having a hard time finding through Google; I guess they are abbreviations for German words, but I don't know German. Is there a glossary with such words?
In particular:

I think VRZ just means defensive retractor, short for "Verteidigungsrückzüger", but what is VV VRZ? (Seen in Andreas Thoma's problems from 2018 preselection)
What is kBP 22.0 (I'm guessing "shortest proof game", but I'm not sure how)? (Seen in the First Prize problem from 2018)


user8201: The glossary at https://pdb.dieschwalbe.de/keywords.jsp?s=all translates many terms from German, English & French. However it is far from complete.
For fairy terms there is also https://www.dieschwalbe.de/lexikon.htm
Any particular questions which remain, please raise here and I will try to answer.

user11144: VV is Vorwärtsverteidigung - if a position is retracted into where Black might interfere (by mating White himself ?!), he may. kbP is indeed SPG.
