, recognizes more than 1200 different fairy pieces. Most (but not all) usual fairy chess pieces fall into one of three classes, although it should be noted that some are hybrid pieces (see the Chinese pieces, for example, which can move without capture as riders yet can only capture as hoppers). It is easy to create a new type of piece by simply combining the movement powers of two or more different pieces.

Movement type

Leapers

A (m,n)leaper is a piece that moves by a fixed vector between its start square and its arrival square. One of the coordinate of the vector 'start square - arrival square' must have an absolute value equal to m and the other one an absolute value equal to n. A leaper moves in the same way to capture or not to capture, the taken unit being on the arrival square. For instance, the knight

Knight (chess)

The knight is a chess piece in the game of chess, representing a knight . It is normally represented by a horse's head, leading some to refer to it informally as a "horse"....

were also leapers: the alfil was a (2,2)leaper (moving exactly two squares diagonally in any direction), and the fers a (1,1)leaper (moving exactly one square diagonally in any direction).

Some pieces can be described as combined leapers, i.e. as pieces having movement capabilities of multiple leapers. The king

ing pieces. One additional property is that the check of a leaper can not be parried by interposing.

All orthodox chessmen belong to either leapers or riders although the Rook does 'hop' when it castles.

The Wazir is an orthogonal 1,0 leaper; the Fers is a diagonal 1,1 leaper; both used in Muslim versions of Chess. The King of standard Chess combines the two.
The Dababba is an orthogonal 2,0 leaper; the Alfil the 2,2 leaper; the Knight is a 1,2 leaper. The Alibaba combines the Dababba and Alfil; while the Squirrel can move to any square 2 units away.
The 'level-3' leapers would be the Threeleaper, a 3,0 leaper, the Tripper, a 3,3 leaper, the Camel, a 1,3 leaper and the Zebra, a 2,3 leaper.

Zero	Wazir	Dababba	Threeleaper
Wazir	Fers	Knight	Camel
Dababba	Knight	Alfil	Zebra
Threeleaper	Camel	Zebra	Tripper

A combined leaper is called an amphibian, if it has a larger range on the board than its components. The simplest amphibian is the Frog, a (1,1)-(0,3) leaper.

Riders

A rider is a piece that can move an unlimited distance in one direction, providing there are no pieces in the way.

There are three riders in orthodox chess: the rook

Rook (chess)

A rook is a chess piece in the strategy board game of chess. In the past the piece was called the castle, tower, marquess, rector, and comes , and non-players still often call it a "castle"....
can move an unlimited number of (1,0) cells and is therefore a (1,0) rider; the bishop is a (1,1) rider; and the queen is a (1,1) or (1,0) rider.

One of the most popular fairy chess riders is the nightrider, which can make an unlimited number of knight moves (that is, 2,1 cells) in any direction (though, like other riders, it cannot change direction half-way through its move).

Sliders are a noteworthy special case of riders which can only move between geometrically contiguous cells. All of the riders in orthodox chess are examples of sliders.

The names of riders are often obtained by taking the name of a leaper which moves a similar cell-size and adding the suffix rider. For example, the zebra is a (3,2) leaper, and the zebrarider is a (3,2) rider.

Riders can create both pin

Pin (chess)

Skewer (chess)

In chess, a skewer is an attack upon two pieces in a line and is similar to a pin . In fact, a skewer is sometimes described as a "reverse pin"; the difference is that in a skewer, the more valuable piece is in front of the piece of lesser or equal value....

Hoppers

A hopper is a piece which moves by jumping over another piece (called a hurdle). The hurdle can usually be any piece of any color. Unless it can jump over a piece, it cannot move. Note that hoppers generally capture by taking the piece on the destination square, not by taking the hurdle (as is the case in checkers). An exception is the locust.

There are no hoppers in orthodox chess, although in xiangqi

Xiangqi

, the cannon captures as a hopper (when not capturing, it is a rider which can not capture - the so-called Chinese pieces (see below) share this characteristic).

The most popular hopper in fairy chess is the grasshopper, which moves along the same lines as an orthodox queen, except that it must hop over some other piece and land on the square immediately beyond it.

Locusts

A locust is any piece which captures by hopping over its victim (as in checkers). It is sometimes considered a type of hopper.

Marine Piece

A marine piece is a combination piece consisting of a rider (for ordinary moves) and a locust (for captures) in the same directions. Marine pieces have names alluding to the sea and its myths, e.g., nereïde (marine bishop), triton (marine rook), mermaid (marine queen), or poseidon (marine king).

By game

Some classes of pieces come from a certain game; often these have a common set of characteristics.

Chinese pieces

Chinese pieces are pieces derived from units found in xiangqi

, the Chinese form of chess. The most common Chinese pieces are the leo, pao and vao (each of which are derived from the Chinese cannon) and the mao (derived from the horse). Those derived from the cannon are distinguished by moving as a leaper when capturing, but otherwise moving as a rider. Less frequently encountered Chinese pieces include the moa, nao and rao.

By special attributes

Royal pieces

A royal piece is one which must not be allowed to be captured. If a royal piece is threatened with capture and cannot avoid capture next move, then the game is lost (this is checkmate). In orthodox chess, each side has one royal piece, the king. In fairy chess any other orthodox piece or fairy piece may instead be designated royal, there may be more than one royal piece, or there may be no royal pieces at all (in which case the aim of the game must be something other than to deliver checkmate, such as capturing all of the opponent's pieces).

Xed pieces

Name	Notes
Crowned pieces	Any piece which, in addition to its normal powers, can move like a King.
Knighted piece	Any piece which, in addition to its normal powers, can move like a knight. For example, an amazon is a knighted queen.

Notations

Parlett's movement notation

In his book The Oxford History of Board Games David Parlett used a notation to describe fairy piece movements. The move is specified by an expression of the form m=, where m stands for "move", and the expression is composed from the following elements:

Distance (numbers, n)

1 - a distance of one (i.e. to adjacent square)
2 - a distance of two
n - any distance in the given direction

Direction (punctuation, X)

* - orthogonally or diagonally (all eight possible directions)
+ - orthogonally (four possible directions)
> - orthogonally forwards
< - orthogonally backwards
<> - orthogonally forwards and backwards
= - orthogonally sideways (used here instead of Parlett's divide symbol.)
>= - orthogonally forwards or sideways
<= - orthogonally backwards or sideways
X - diagonally (four possible directions)
X> - diagonally forwards
X< - diagonally backwards

Grouping

/ - two orthogonal moves separated by a solidus
Slash (punctuation)

The slash is a punctuation mark. It is also called a virgule, diagonal, stroke, forward slash, oblique dash, slant, separatrix, scratch comma, over, slak, whack....
denote a hippogonal
Hippogonal

A hippogonal chess move is one similar to a knight 's move. That is, a leap m squares in one of the orthogonal directions, and n squares in the other, for integer values of m and n....
move (i.e. jumping like knights)

Additions to Parlett's

The following can be added to Parlett's to make it more complete:

Conditions under which the move may occur (lowercase alphanumeric, except n)

(default) - May occur at any point in the game
i - May only be made on the initial move (eg. pawn's 2 moves forward)
c - May only be made on a capture (eg. pawn's diagonal capture)
o - May not be used for a capture (eg. pawn's forward move)

Move type

(default) - Captures by landing on the piece; blocked by intermediate pieces
~ - Leaper (leaps)
^ - Locust (captures by leaping; implies leaper)

Grouping (punctuation)

/ - two orthogonal moves separated by a solidus
Slash (punctuation)

The slash is a punctuation mark. It is also called a virgule, diagonal, stroke, forward slash, oblique dash, slant, separatrix, scratch comma, over, slak, whack....
denote a hippogonal
Hippogonal

A hippogonal chess move is one similar to a knight 's move. That is, a leap m squares in one of the orthogonal directions, and n squares in the other, for integer values of m and n....
move (i.e. jumping like knights); this is in Parlett's, but is repeated here for completeness
, (comma) - separates move options; only one of the comma-delimited options may be chosen per move
- grouping operator; see nightrider
- - range operator

Other:

& - See text for details

The format (not including grouping) is: <conditions> <move type> <distance> <direction> <other>

On this basis, the traditional chess moves are:

King: 1*
Queen: n*
Bishop: nX
Rook: n+
Pawn: o1>, c1X>, oi2>
Knight: ~1/2

Ralph Betza's "funny notation"

Ralph Betza created a classification scheme for fairy chess pieces (including standard chess pieces) in terms of the moves of basic pieces with modifiers.

For example, the FIDE Rook, which can be described as a Wazir-rider, can be notated WW, with shorthand R. The FIDE Bishop can be notated as a Fers-rider, or FF. Finally, a FIDE pawn can be notated fmWfcF (or fcFfmW), meaning it is a piece that moves forward like a Wazir, and captures forward like a Fers (and has no other moves). This is setting aside the initial two-square move and promotion.

Kraken	~n/m		Leap to any square on the board, including the one it is currently on (leaping to the current square has the effect of passing a move). Compare with universal leaper.
Leeloo		Quintessential Chess	Combines the powers of Quintessence and Rook
Leo	on*, c^&	Chinese	Combines the powers of the pao and vao; it moves like a queen when not capturing (that is, a (1,0) or (1,1) rider), but captures by leaping over an intervening piece and taking the piece on the leo's destination square (the captured piece can be any number of squares beyond the hurdle).

The square it is on after its orthogonal move must be vacant. For example, if a white mao is on b2 and there is a white pawn on b3, the mao cannot move to a4 or c4; if the pawn is on c3, however, it can move to both those squares (because the first part of the move is orthogonal, not diagonal).

Nao		Chinese	A Chinese nightrider - moves as a normal nightrider (that is, a (2,1) rider) when not capturing, but which captures by leaping over an intervening piece and taking the piece on the nao's destination square (the captured piece can be any number of knight-moves beyond the hurdle).
Nightrider	n(1/2) (in same direction)		A rider which moves any number of 2,1 cells (i.e., knight moves) in the same direction. A nightrider on b2 on an empty board, therefore, can move to a4, c4, d6, e8, d3, f4, h5 and d1. A pawn of the opposing colour on d6 could be captured, but the nightrider could not move any further in that direction (i.e. it couldn't move on to e8). A pawn on b3, for example, would have no effect. On diagrams, the nightrider is usually represented by an inverted knight. One of the most popular fairy pieces. See diagram below.
Pao		Chinese	Moves like a rook when not capturing (that is, a (1,0) rider), but captures by leaping over an intervening piece and taking the piece on the pao's destination square (the captured piece can be any number of squares beyond the hurdle).

Quintessence			A nightrider who takes 90-degree turns in a zig-zag manner on each step. First described in 2002 by Jörg Knappen and found in several chess variants since then.
Rao		Chinese	A Chinese rose - moves as a normal rose when not capturing, but captures by leaping over an intervening piece and taking the piece on the rao's destination square. The captured piece can be any distance beyond the hurdle.
RennCavalier		Renniasance Chess	Moves in the same move one square diagonally and any number of squares othogonally or any number of squares orthogonally and one diagonally. t has two paths to the same target square and must make at least a blockable knight's move. Called Cavalier in RennChess, but the name Cavalier is used for other pieces as well. Renniasance Chess was invented by 1980 by Eric V. Greenwood.
RennDuke		Renniasance Chess	Moves in the same move one square orthogonally and then any number of squares diagonally or any number of squares diagonally and then one straight. It has two paths to the same target square and must make at least a blockable knight's move. Called Duke in RennChess, but the name Duke is used for other pieces as well.

Sometimes called Western chess or international chess to distinguish it from History of chess and other chess variants, the current form of the game emerged in Southern Europe during the second half of the 15th century after evolving from similar, much older...
Rose			Moves as a nightrider, except that rather than moving in a straight line, it moves along pseudo-circular ones. A rose standing on e1 on an empty board, for instance, can move to any of the squares on the large circle c2, b4, c6, e7, g6, h4 and g2; as well as c2 and a1; or d3 and b4; or d3, e5 and g6; or f3, e5, c6 and a5; or f3 and h4. As with the nightrider, an opposite-coloured piece on any one of these squares can be captured, but prevents the rose from progressing any further along that line. See diagram below.
Spy	2>, 2=, (1/1)>	Chess Empire	The spy can move two spaces forwards or sideways, or can move like a knight one forward and then one horizontally or vice versa. It can leap over pieces and can only move two spaces; thus, it is "trapped" on its own color like a bishop.
Squirrel	~0/2, ~1/2, ~2/2	Fairy Chess Problems	Jumps to any field in a distance of 2. It was discovered independently several times and is also known as Centurion or Castle.
Superpawn	on>, cnX>	Fairy Chess Problems	Moves without capture any number of fields forward, captures diagonally forwards like a bishop. Promotes on the 8th rank. Cannot capture en passant nor be captured en passant. May be placed in the first rank. Invented by Werner Speckmann in 1967.
Superqueen			See "Amazon"
Universal leaper			Leap to any square on the board apart from the one it is on. Compare with kraken.
Unicorn			A name usually given to a B+N piece. In Raumschach it is a triagonal rider, moves through the vertices of the cubes. See diagram below.
Vao		Chinese	Moves like a bishop when not capturing (that is, a (1,1) rider), but captures by leaping over an intervening piece and taking the piece on the vao's destination square (the captured piece can be any number of squares beyond the hurdle).
Wazir	1+		Move one square orthogonally in any direction.
Zebra	~2/3
Zero	~0/0		A piece which can make a zero move, i. e., jump and land on its starting square without any side effects. This gives the player the option to pass a move. Sometimes used as a component to more complex pieces.
Zurafa		Tamerlane Chess Tamerlane Chess Tamerlane Chess is a strategic board game related to chess and derived from shatranj. It was developed in Persian_Empire during the reign of Timur, also called Tamerlane ....	Starts with a (1,4) leap (like the modern Giraffe) and may continue moving outwards as a rook.
