as well as "x" for a cross, "o" for a circle

"a" for archbishop and "c" for chancelor.
It uses two characters for a position, not one (the second character
shows the side of the piece/pawn); this means that the data will
work correctly on case-insensitive systems.
Wikipedia itself works correctly with case-sensitive data,

Hinweise

Ein paar praktische Hinweise:

  • Achte darauf, dass du das Grundschema nicht veränderst, insbesondere lasse die Zeichen "|" und "=" da, wo sie sind.
  • Du kannst das Zeichen "|" nicht im Titel oder der Beschreibung verwenden.
  • Falls du das Zeichen "=" im Titel oder in der Beschreibung verwenden möchtest, musst du es in nowiki-Elemente einschließen.
  • Du kannst Formatierungen wie fett oder kursiv benutzen.
