Fairy Chess Classification Project
The Fairy Chess Classification (v.0.1, 22.05.2021)
View the DB:
In these descriptions of fairy elements, the normal meanings of common orthodox chess terms or concepts such as ‘square’, ‘capture’, ‘promotion’ or ‘castling’ will be assumed to be understood, though these normal meanings will often need modification when applied to fairy elements. However, the term ‘move’ will be used to mean a non-capturing move as opposed to a capture (though ‘move-length’ would be taken as applying to a move or capture), ‘unit’ will be used to mean any piece or pawn, and ‘piece’ to mean any unit apart from a pawn or king. Also, any reference to the royal powers of a king will be taken to apply equally to any other royal piece used instead of a king.
In this classification, the fairy elements divide into the four ‘Main Groups’ of Stipulations, Pieces, Conditions and Boards, these Main groups being divided into Groups and Sub-Groups.
Note: Some elements can be included in more than one group. We have chosen the commonly followed classification. Such cases are indicated when they occur. Generally, the rules applying to one element in a group can be applied to another group to create new elements or sub-groups in that group. For example the rules of the Vertical Cylinder can be applied to particular pieces as an attribute to create “Vertical Cylinder pieces”. The rules of Circe can be applied to specific pieces to create “Circe pieces”. The attributes of certain pieces can be applied to all pieces to create a condition as in “Chameleon Chess”. Certain stipulations can also be interpreted as conditions and vice versa. See also under 1.1: Goals.
From v.0 (22.04.2021) to v.0.1 (22.05.2021):
- Corrections and additions made
- Now a total of 422 elements
- All elements in JF Fairy terms db included now!
- Andrew Buchanan has joined the project. Welcome!
Going forward, we plan to add more elements from all these sources as well as any interesting elements that are freshly invented.
We will also add more information to each element like history, popularity, solving program support and example problems.
Also planned is a user interface to search and explore the elements.
In these dark days, some light and order!
We welcome you to join us!
