Albino
A chess problem theme in which, at some point in the solution, a white pawn on its starting square makes each of its four possible moves (forward one square, forward two squares, capture to the left, capture to the right). If the same behaviour is exhibited by a black pawn, it is a Pickaninny theme.
Allumwandlung
A chess problem theme in which the solution includes pawn promotions to all possible pieces (in orthodox chess, to bishop, knight, rook and queen; in fairy chess, possibly to fairy pieces).
anti-Bristol
The interference of one black piece by another like-moving one on the same line (if the pieces are on different lines, it is a Holzhausen).
anticipation
If the theme and setting of a particular problem has already appeared in an earlier problem without the knowledge of the later composer, the problem is said to be anticipated. The position does not have to be exactly the same, just very similar. Where this is done deliberately by the later composer, the term plagiarised is used.

Why this record matters
The phrase “wikimedia glossary list article” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Sep 23, 2026. The linked authority identifier is Q3419547. None of the 0 selected statements returned an explicit reference.
A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
