Let’s say I wanted to ask a question about a chess problem I found, to learn about the strategy behind it, but I also want to give attribution to the author. However, I don’t know who the author is and extensive searching hasn’t brought up anything useful. What can/should I do to find the author then? Are there any known tools that could help aid me?
One way that you can find who created a chess problem is by using chess problem databases, which are more or less giant Wikipedias for chess problems. Here are a few that are easy to use and widely used, along with small guides on how to use them.
Note: Instead of the English notation “N” for knight, YACPBD (the site’s acronym) uses “S” for the knight, as it reserves “N” for the fairy chess pieces called [nightriders](https://en.wikipedia.org/wiki/Nightrider_(chess).
Forewarning: The Die Schwalbe database is a German site that uses German chess notation.
