-\title{Typesetting Chess in \LaTeX with the \package{skak} Package\\
-Version 1.5.2}
-\author{Torben Hoffmann\\ e-mail: \texttt{torben.lehoff@gmail.com}}

-\begin{document}
-\maketitle
-
-\begin{abstract}
-  This user guide shows how to use an enhancement to the existing
-  package for typesetting chess in \LaTeX (\package{skak}). The
-  primary improvement over the old package is that it has become
-  easier to typeset chess games with this new package.

-\section{Terms of Usage}
-\label{sec:terms-usage}
-
-This package is distributed under the terms described in the Latex
-Project Public Licence, i.e.,
-
-\begin{quote}
-  This software is copyright but you are granted a license which gives
-  you, the ``user'' of the software, legal permission to copy,
-  distribute, and/or modify the software. However, if you modify the
-  software and then distribute it (even just locally) you must change
-  the name of the software to avoid confusion.

-\section{Installing the \package{skak} Package}
-\label{sec:install}
-
-I could not get the makefile to do the job, so if someone could help
-me out on this I would be very glad indeed.
-
-Basically all you have to do is to follow the guidelines in the
-makefile. First you create all the required directories (stated in the
-\texttt{install} section of the makefile) and then you run the
-\texttt{make install} command. Remember to run \texttt{texhash} after
-you have updated your texmf tree.
-
-Sorry that it is not working $100\%$--- I just do not have the time for
-it right now.
-
-If you cannot get the things working just put the files where \TeX and
-the other tools can find them and you will be just fine.
-
-For Windows user I can recommend the MikTeX installation since it has
-skak as a package and all you have to do is to use the MikTeX
-installation tools and select installation of skak and you're up and
-running.
-
-Ultimately the skak package should be documented using the \LaTeX
-standard documentation, but that is a major undertaking that will not
-happen right now.
-
-\subsection{Using the \package{lambda} Package}
-\label{sec:using-lambda}
-
-The \package{skak} package uses the \package{lambda} package to do
-some of the hard processing necessary to allow the \pgn notation as
-input --- since it is not standard in \LaTeX distributions it is
-included in the distribution of the \package{skak} package.
-
-
-%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
-\section{Basic usage of the \package{skak} package}
-\label{sec:basic-usage}
-
-Once the \package{skak} package has been installed you only need to
-know very few things in order to produce nicely typeset chess games:
-
-\begin{itemize}
-\item write \verb|\usepackage{skak}| in the preamble.
-\item the \command{newgame} command.
-\item the \command{mainline} command.
-\item the \command{variation} command.
-\item the \command{showboard} command.
-\end{itemize}
-
-As an example I will describe some moves from the Ruy Lopez opening
---- please note that the comments are just idle talk. In the left
-column the input is shown and the corresponding output is shown in the
-right column.
-
-\begin{LTXexample}
-\newgame
-\mainline{1.e4 e5 2. Nf3 Nc6 3.Bb5}
-
-\showboard
-\end{LTXexample}
-
-The \command{newgame} command sets up the internal board or a new
-game. The \command{mainline} command does two things: it typesets the
-moves and updates the board so that \command{showboard} will show the
-current board position.
-
-\begin{LTXexample}
-\mainline{3...a6} \savegame{pap1}
-Rarely used these days,
-\variation{3...Nf6} is more in
-fashion since blah blah...
-\mainline{4.Ba4}
-
-\showboard
-\end{LTXexample}
-
-
-
-This example shows that if it is black to move the move number shoud
-be followed by three periods. Furthermore, it also shows that the
-\command{variation} command merely typesets the moves --- it does
-\emph{not} update the board, but apart from that it expects the same
-input as \command{mainline}.
-
-The four commands introduced in this section will enable you to
-comment your games with minimal effort and still get great results ---
-in fact most chess books can be writen using only these commands!
-
-But the \package{skak} package offers a lot more that can make chess
-typesetting easier for your --- these features are the topics of the
-next two sections.
-
-
-
-%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
-\section{Intermediate Usage of the \package{skak} Package}
-\label{sec:intermediate}
-
-This section describes how to
-\begin{itemize}
-\item do game management,
-\item add ornaments to the board and
-\item controlling some aspects of showing the board.
-\end{itemize}
-
-
-\subsection{Game Management}
-\label{sec:game-management}
-
-Returning to the Ruy Lopez example suppose you want to go into details
-about a number of variations after white's third move, preferably
-showing the board in all the lines you describe.
-
-One way to do this is to use the \command{hidemoves} command like
-this:
-
-\begin{LTXexample}
-\newgame
-\mainline{1.e4 e5 2. Nf3 Nc6 3.Bb5}
-
-\showboard
-\end{LTXexample}
-
-\begin{LTXexample}
-\mainline{3...a6} blah blah
-
-\showboard
-
-\end{LTXexample}
-
-\begin{LTXexample}
-\newgame
-\hidemoves{1.e4 e5 2. Nf3 Nc6 3.Bb5}
-\mainline{3...Nge7} blah blah
-
-\showboard
-\end{LTXexample}
-
-This is, admittedly, a labourious way of doing it, but the example
-shows how \command{hidemoves} can fast-forward you to any point in a game.
-
-
-\package{skak} offers you ways of storing game positions
-\begin{itemize}
-\item in memory or
-\item in a file.
-\end{itemize}
-
-The former is done using the \command{storegame} and
-\command{restoregame} commands like this:
-
-\begin{LTXexample}
-\newgame
-\mainline{1.e4 e5 2. Nf3 Nc6 3.Bb5}
-\storegame{game1}
-\mainline{3...a6 4.Ba4 b5}
-
-\showboard
-\restoregame{game1}
-
-\mainline{3...Bd7}
-\showboard
-\end{LTXexample}
-
-
-Saving and loading to/from a file is the same just with the commands
-\command{savegame} and \command{loadgame}.
-
-
-\section{Ornaments}
-\label{sec:ornaments}
-
-
-
-\subsection{Showing the Board}
-\label{sec:showing-board}
-
-We have already seen \command{showboard} in action, but is is possible
-to alter the way the board looks like.
-
-With the \command{mover}\footnote{\command{mover} only works if the \package{skak} is loaded with the ps option.} command one can request that a little marker
-is shown next to the board indicating who is to move next.
-
-\begin{LTXexample}
-\newgame
-
-\showboard
-
-\end{LTXexample}
-
-\begin{LTXexample}%9 okay
-
-\mainline{1.d4}
-
-\showboard
-\end{LTXexample}
-
-This can be turned off with \command{moveroff}. You can also remove
-the notation around the board using \command{notationoff} which gives
-this appearance:
-
-\begin{LTXexample}
-\newgame
-\notationoff
-\showboard
-
-\end{LTXexample}
-
-The notation is added again after one has issued
-\command{notationon}. \notationon
-
-A more elaborate explanation of how the appearance of the notation
-around the board is configured can be found in \cite{chessnfss}.
-
-Although it is rarely seen is chess books \package{skak} offers
-the possibility of showing the board from black's perspective
-using the
-\command{showinverseboard} command.
-
-\begin{LTXexample}
-\newgame
-\showboard
-
-\end{LTXexample}
-
-If you are writing about an opening from black's point of view this
-command/feature could be a welcome refreshment in presentation style.
-
-
-\subsection{Handy Commands}
-\label{sec:handycommands}
-
-By requst of users and own usage a couple of handy commands have been
-added to \package{skak} that you might find useful too.
-
-\command{wmove\{\emph{move}\}} typesets a single move, whereas
-\command{bmove\{\emph{move}\}} does the same only with leading
-ellipses (see \ref{sec:advanced-usage}for in-depth explanation). This
-is useful for short remarks like:
-
-\begin{LTXexample}
-\bmove{Nd4} would have been better.
-\end{LTXexample}
-
-
-\command{lastmove} is a shorthand for commenting on the last move made:
-
-\begin{LTXexample}
-\newgame
-\mainline{1.a3}
-
-\lastmove{} is bad.
-\end{LTXexample}
-
-%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
-\section{Advanced Usage}
-\label{sec:advanced-usage}
-
-This section will describe some features of the \package{skak} package
-that allows you to control a lot with regards to the typesetting of
-moves as well as how the board is shown.
-
-Furthermore, we will take a look at how the board is set up in
-arbitrary positions and how the input language can be changed.
-
-
-\subsection{Tailoring of the Board Appearance}
-\label{sec:tail-board-appe}
-
-In additon to the ornaments and showing the board upside down
-described in \ref{sec:intermediate} one can choose to show only a
-subset of the pieces actually on the board.
-
-The simple commands \command{showonlywhite} and \command{showonlyblack} shows
-only one colour on the board:
-
-\begin{LTXexample}
-\newgame
-\mainline{1.e4 e5 2. Nf3 Nc6 3.Bb5}
-
-\showonlywhite
-\showboard
-
-\end{LTXexample}
-
-\begin{LTXexample}
-\showonlyblack
-\showboard
-\end{LTXexample}
-
-
-This is often used when describing openingswhere one wants to focus on
-the merrits of the piece set-up on one side without considering how
-the other side is positioned.
-
-In addition to the commands for showing only one colour it is also
-possible to show any subset of the pieces on the board using the
-\command{showonly} command that takes a comma sperated list of piece
-names as argument:
-
-\begin{LTXexample}
-The pawn structure is
-now like this:
-
-\showonly{P,p}
-\showboard
-\end{LTXexample}
-
-The piece names are the standard English name with the addition that
-white pieces are denoted by upper case and black's by lowercase. Pawns
-are P and p.
-
-It is also possible to do the opposite of \command{showonly} using
-\command{showallbut}:
-
-\begin{LTXexample}
-\showallbut{P,p}
-\showboard
-\end{LTXexample}
-
-
-\subsection{Setting up the Board}
-\label{sec:setting-up-board}
-
-So far we have only looked how to start a new game, but you can also
-set up the board in \emph{any} position using the command
-\command{fenboard}:
-
-Forsyth-Edwards Notation (FEN) is a standard used to describe chess
-positions. It starts with a description of the contents of the ranks
-on the board. The ranks are separted by a slash starting with the
-eighth row, so if you want to write down the FEN of a
-position you should be seated as white and work your way dow the
-board. The pieces are designated using the stardard English piece
-names.
-
-After the position of the pieces the following information is given
-separated by spaces:
-\begin{itemize}
-\item who it is to move (w or b).
-\item castling options left for white. - for none, and K and Q for
-  options to castle kingside or queenside for white and k and q for black
-\item en passant square, if applicable otherwise a -.
-\item number of halfmoves since the last capture.
-\item the move number.
-\end{itemize}
-
-
-\begin{LTXexample}
-\fenboard{r5k1/1b1p1ppp/p7/1p1Q4/
-2p1r3/PP4Pq/BBP2b1P/R4R1K w - - 0 20}
-
-\mbox{}
-\bigskip
-
-\showboard
-
-
-\mainline{20.Qxb7 Rae8 21.Qd5}
-
-\end{LTXexample}
-
-
-\subsection{Typesetting Style}
-\label{sec:typesetting-style}
-
-There are a couple of ways to configure how the move are typeset as
-described in the following.
-
-
-\subsubsection{\command{styleA}}
-\label{sec:stylea}
-
-The \command{styleA} will switch the typesetting to the way it has
-been the standard in Denmark and --- I believe --- Germany.
-
-\begin{LTXexample}
-\newgame
-\styleA
-
-\mainline{1.e4 c5 2.Nf3 Nc6} 
-\end{LTXexample}
-
-
-\subsubsection{\command{styleB}}
-\label{sec:styleb}
-
-The style selected by \command{styleB} is the default one.
-
-\begin{LTXexample}
-\newgame
-\styleB
-
-\mainline{1.e4 c5 2.Nf3 Nc6} 
-\end{LTXexample}
-
-
-\subsubsection{\command{styleC}}
-\label{sec:styleb}
-
-The style selected by \command{styleC} is an elaboration on
-\command{styleB}: it typesets the moves line by line for each move for
-the mainline but on the same line for variations --- this style is
-used in many books these days, but look the best in a two-column
-setting where the linewidth is small.
-
-\begin{LTXexample}
-\newgame
-\styleC
-
-\mainline{1.e4 c5 2.Nf3 Nc6} 
-
-Interesting how \variation{2...d6} is blah blah.
-\end{LTXexample}
-
-\styleB
-
-
-\subsubsection{\command{variationstyle} and  \command{mainlinestyle}}
-\label{sec:variationstyle}
-
-Configuration of these commands allows for total control of the
-typesetting of the mainline and variations, they default to:
-
-\begin{verbatim}
-\def\mainlinestyle{\bfseries}% could also contain
-                             % definitions of the
-                             % various style options
-\def\variationstyle{}% as with mainlinestyle
-\end{verbatim}
-
-They are used by \command{styleC} to control the switching back and
-forth between a tabbed environment and normal typesetting:
-
-\begin{verbatim}
-\def\mainlinestyle{\styleC\bfseries}
-\def\variationstyle{\styleB}
-\end{verbatim}
-
-
-
-\subsubsection{\command{longmoves} and \command{sanmoves}}
-\label{sec:commandlongmove}
-
-The \command{longmoves} command will ensure that the full move, i.e., including the from
-square is typeset. This is also know as \emph{algebraic} notation ---
-can be quite handy when writing about chess for children or other
-newcommers to chess notation.
-
-\begin{LTXexample}
-\newgame
-\longmoves
-
-\mainline{1.e4 c5 2.Nf3 Nc6} 
-\end{LTXexample}
-
-\shortmoves
-
-The \command{shortmoves} command returns things to normal.
-
-
-\subsection{Input Language}
-\label{sec:input-language}
-
-The \package{skak} package by default uses the English letters for the
-pieces, i.e., K for King, Q for Queen, R for Rook, B for Bishop, N for
-Knight and P for Pawn.
-
-The \command{newskaklanguage} command makes it possible to define
-other languages than English, e.g., suppose I want to use the Danish
-piece letters:
-
-\begin{LTXexample}
-\newskaklanguage{danish}{KDTLSB}
-
-\skaklanguage[danish]
-
-\newgame
-\mainline{1.e4 c5 2.Sf3 Sc6} 
-\end{LTXexample}
-
-
-
