Template:Chess diagram/doc

These templates shows a chess diagram, a graphic representation of a position in a chess game, using standardised symbols resembling the pieces of the standard Staunton chess set. The default template for a standard chess board is Chess diagram. This documentation covers all related templates.

Templates
There are several standard chess diagram templates:

There are also templates for chess variants:

Syntax
The syntax is basically the same for all chess diagram templates.

Parameters:


 * – defines horizontal alignment (floating) of the whole table, must be  or   (or nothing)
 * – the text which appears above the diagram, may be empty;
 * - specifies the size of each square in pixels, the default is 26.
 * - specifies whether the rows are numbered. Options are: left, right, both (default) or neither.
 * - specifies whether the columns are lettered. Options are: top, bottom, both (default) or neither.
 * – define corresponding squares of the chessboard, see below;
 * – the text which appears beneath the diagram, may be empty; optional – can be left out (currently not in the other templates)

A square is defined by the name of piece or empty parameter. The names of the pieces are those given in algebraic notation:


 * [[Image:Chess kll45.svg|26px]] [[Image:Chess kld45.svg|26px]] [[Image:Chess kdl45.svg|26px]] [[Image:Chess kdd45.svg|26px]] k = king
 * [[Image:Chess qld45.svg|26px]] [[Image:Chess qll45.svg|26px]] [[Image:Chess qdd45.svg|26px]] [[Image:Chess qdl45.svg|26px]] q = queen
 * [[Image:Chess rll45.svg|26px]] [[Image:Chess rld45.svg|26px]] [[Image:Chess rdl45.svg|26px]] [[Image:Chess rdd45.svg|26px]] r = rook
 * [[Image:Chess bld45.svg|26px]] [[Image:Chess bll45.svg|26px]] [[Image:Chess bdd45.svg|26px]] [[Image:Chess bdl45.svg|26px]] b = bishop
 * [[Image:Chess nll45.svg|26px]] [[Image:Chess nld45.svg|26px]] [[Image:Chess ndl45.svg|26px]] [[Image:Chess ndd45.svg|26px]] n = knight
 * [[Image:Chess pld45.svg|26px]] [[Image:Chess pll45.svg|26px]] [[Image:Chess pdd45.svg|26px]] [[Image:Chess pdl45.svg|26px]] p = pawn

These letters are combined with either "l" for Light=White, or "d" for Dark=Black. So "kl" is White's king, and "nd" is Black's knight.

An empty square is written either using underscores, spaces, or nothing at all. Two spaces are recommended.

Standard diagram
This diagram is recommended for common use as a main diagram in the articles on chess openings, endings, games, positions etc. See the corresponding code below.

Diagram with both captions
It may be convenient to use this in the articles on chess problems. Please note that in the header and footer you can use bolds or italics. You can also use  to break the lines.



Diagram without captions
See the corresponding code below. If you don't want the captions, just remove them, but don't delete the second "|" pipe character for the caption above; it is possible to delete the last pipe for the longer caption below.

The diagram floats to the left to illustrate the use of the first parameter.

Movement example
This can be used to show how pieces move.

In the board on the right, it is shown that the white queen can go any distance in any of these directions.

Another method for the rook example:

Small diagram
This one may be useful in articles with many diagrams. It uses another template named Chess diagram small.

The small diagrams can have header, too.

Different board size
Chess boards of non-standard dimensions need special templates. There are templates for the following boards:

Alternative way to place the pieces: FEN
It is possible to populate the board using Forsyth–Edwards Notation, instead of positional parameters.

To do this, the "fen" parameter is used. For instance, this is the opening board of a chess game, defined using the "fen" parameter "rnbqkbnr/pppppppp/8/8/8/8/PPPPPPPP/RNBQKBNR":

It is also possible to show "fairy" pieces using the FEN notation. However, because the FEN notation uses uppercase and lowercase to denote the color of the piece, it is not possible to display the inverted knight fairy piece (denoted by "N") using the fen parameter. Here is a board where the pawns are replaced by fairy pieces:

While the "fen" parameter was first developed and tested with 8x8 boards, support for other sized boards is available. For example, here is the Grand Chess starting positiong represented with an FEN board:

Displaying the board from the Black's point of view
The "reverse=true" parameter causes the board to be shown from Black's point of view, that is, with the h8 square at lower-left corner, and a1 at the upper-right. This works for all sizes of the normal chessboard template, but not for the Alice, Bughouse, Omega, or Raumschach templates. Here, the same FEN notation as in the previous example produces a board with Black's starting position at the bottom.
