{{term|term= Albino |content = [[Albino (chess)|Albino]] {{anchor|Albino|Albinos}} }}
{{defn|defn= A [[#problem|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|Pickaninny]]'' theme.}}

{{term|term= Allumwandlung |content = [[Allumwandlung]] {{anchor|Allumwandlung}} }}
{{defn|defn= A [[#problem|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|fairy chess]], possibly to [[fairy pieces]]).}}

{{term|term= anti-Bristol |content = anti-Bristol {{anchor|Anti-Bristol}} }}
{{defn|defn= 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|Holzhausen]]'').}}

{{term|term= anticipation |content = anticipation {{anchor|Anticipation}} }}
{{defn|defn= If the [[#theme|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. There is a real chance of anticipation if the problem has a relatively simple theme, since there are only a finite number of positions and themes, and chess problems have been composed for hundreds of years. Anticipations are not always noticed immediately, however.}}

{{term|term= aristocrat |content = aristocrat {{anchor|Aristocrat|aristocrats}} }}
{{defn|defn= A problem in which no [[pawn (chess)|pawns]] are in the initial position.}}
