Template:Chess diagram/doc

This is a documentation subpage for Template:Chess diagram. It may contain usage information, categories and other content that is not part of the original template page.

This template uses Lua: Module:Chessboard

There are several standard chess diagram templates:

• Template:Chess diagram (square size 26x26 px)
• Template:Chess diagram small (square size 22x22 px)
• Template:Chess diagram 4x4 (square size 26x26 px)
• Template:Chess diagram 4x5 (square size 26x26 px)
• Template:Chess diagram 4x8 (square size 26x26 px)
• Template:Chess diagram 5x5 (square size 26x26 px)
• Template:Chess diagram 5x6 (square size 26x26 px)
• Template:Chess diagram 6x6 (square size 26x26 px)
• Template:Chess diagram 8x10 (Capablanca chess square size 26x26 px)
• Template:Chess diagram 8x12 (square size 26x26 px)
• Template:Chess diagram 9x9 (square size 26x26 px)
• Template:Chess diagram 10x10 (square size 26x26 px)
• Template:Chess diagram 10x10 small (square size 22x22 px)
• Template:Chess diagram 12x12 (square size 26x26 px)
• Template:Chess diagram 16x16 (square size 26x26 px)
• Template:Chess diagram 24x24 (square size 26x26 px)

There are also templates for chess variants:

• Template:Alice chess diagram (Alice Chess, square size 22x22 px)
• Template:Bughouse chess diagram (Bughouse chess, square size 22x22 px)
• Template:Omega Chess diagram (Omega Chess with 10x10 board + 4 corners, 22x22 px)
• Template:Raumschach diagram (5x5x5 board for Three-dimensional chess, 22x22 px)

The syntax is basically the same for all of them.

{{Chess diagram
| <alignment> (param #1)
| <header>    (#2) 
| size =
| numbers =
| letters =
| <a8> | <b8> | ... | <h8>  (#3 to ...
| <a7> | <b7> | ... | <h7>
...
| <a1> | <b1> | ... | <h1>  ( ... #66)
| <footer> (#67)
| reverse = 
}}

When the chess board is 8x8, there is an alternative syntax (see #Alternative way to place the pieces: FEN below):

{{Chess diagram
| fen =
| align =
| clear = 
| header = 
| footer =
| size =
| numbers =
| letters =
| reverse =
}}

Parameters:

• <alignment> – defines horizontal alignment (floating) of the whole table, must be tright or tleft (or nothing)
• <header> – the text which appears above the diagram, may be empty;
• size - specifies the size of each square in pixels, the default is 26.
• numbers - specifies whether the rows are numbered. Options are: left, right, both (default) or neither.
• letters - specifies whether the columns are lettered. Options are: top, bottom, both (default) or neither.
• <a8>, <b8>, ... <h1> – define corresponding squares of the chessboard, see below;
• <footer> – 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:

• k = king
• q = queen
• r = rook
• b = bishop
• n = knight
• p = pawn

There are also some fairy chess pieces available:

• a = archbishop (knight+bishop compound)
• c = chancellor (knight+rook compound)
• f = inverted king
• g = inverted queen
• m = inverted rook
• j(e) = inverted bishop
• N(s) = inverted knight
• h = inverted pawn
• z = champion (for Omega Chess)
• w = wizard (for Omega Chess)
• t = fool (for Omega Chess)
• M = mann
• C = centaur

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.

• <space> = empty square

You can also use "xx" for a black cross, "ox" for a white cross, "xo" for a black circle on an empty square or "oo" for a white one.

• xx = black cross/x
• ox = white cross/x
• xo = black circle
• oo = white circle

When showing movement directions on the board, arrows are available

• ul = up & left
• ua = up
• ur = up & right
• la = left
• lr = left & right
• ud = up & down
• ra = right
• dl = down & left
• da = down
• dr = down & right

Numbers can also be added to squares by using "x0" for 0, "x1" for 1, "x2" for 2, ..., "x9" for 9.

• x0
• x1
• x2
• x3
• x4
• x5
• x6
• x7
• x8
• x9

Mate in two.
This problem uses partial retrograde analysis method.

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 <br> to break the lines.

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.

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.

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":

{{Chess diagram|fen=rnbqkbnr/acfghzwt/8/8/8/8/ACFGHZWT/RNBQKBNR|align=tleft}}

5									5
4									4
3									3
2									2
1									1
	a	b	c	d	e	f	g	h

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:

Only 8x8 boards can use the "fen" parameter. For other size boards, positional parameters should be used.

{{Chess diagram|fen=rnbqkbnr/pppppppp/8/8/8/8/PPPPPPPP/RNBQKBNR|align=tleft|reverse=true}}

4									4
5									5
6									6
7									7
8									8
	h	g	f	e	d	c	b	a

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.
