See below for details. + +Changed Code: As \cs{longmoves} doesn't work with \cs{variation} +anyway \cs{variation} now use always \cs{shortmoves}. + +Bug correction: \skaksty forgets to store comments after castling +moves. Code to correct this has been added to \xskak. + +Bug correction: \xskak didn't print check and mate symbol after +castling moves due to wrong position of braces. + +\item[2008-07-28 (Version 1.1)] +Bug correction: Added the code for the promotion piece to the SAN and +LAN notation. + +Bug correction: Remove some spurious spaces. + +\end{description} + + +\section{Introduction} + +\Xskak\footnote{License: \LaTeX\ Project Public License} is an extension for \skaksty -- and as \xskak is an extension +(and not a replacement) the main work is still done by \skaksty so +please read first the documentation of \skaksty as I'm not explaining +the \packagename{skak} commands in this documentation. + + +\Skaksty is a package from Torben Hoffmann which can parse and print +chess games given in (a subset of) the PGN notation. + +The main features of \packagename{xskak} are: + +\begin{itemize} +\item \packagename{xskak} can handle an extended set of PGN. + +\item \packagename{xskak} +can parse and store an arbitrary number of chess games in PGN. The +games can be exported and imported and all positions and moves can be +retrieved at anytime. + +\item \packagename{xskak} can +handle an arbitrary number of printing styles to distinguish +the different variations levels. + +\end{itemize} + +\minisec{Extended PGN handling} + +When handling a PGN chess parsers at first have to split the notation +in different chunks. I will call this step the \emph{PGN parser}. +As an example\\[1ex]\mbox{}\quad {\ttfamily 15.Ne5!+ +\$3 \{This breaks the black defense\} (15.Re1? Kg8!)}\\[1ex] contains as +chunks a \emph{move number} (\texttt{15.}), a \emph{move} +(\texttt{Ne5}), \emph{short move comments} (\texttt{!+}), a +\emph{NAG} (\texttt{\$3}), a \emph{comment} (\texttt{\{This breaks +the black defense\}}) and a \emph{variation} (\texttt{(15.Re1? +Kg8!)}). + +Neither \packagename{skak} nor \packagename{xskak} can handle all +legal PGN's. \Skaksty can only handle PGN's which contains move +numbers, moves and short comments. \packagename{xskak} can +additionally handle NAG's and a special form of comments. None of the +packages can currently parse PGN's with variations. + + +\minisec{Storing moves} + +After the splitting of the PGN the chunks are processed further. +Depending on the type of the chunk different actions are taken. The +most important subprocess is the \emph{move parser}. It takes the +move, retrieves from somewhere the current (FEN-)position of the game +and tries to figure out what the move is exactly doing. + +In \packagename{xskak} only the commands \cs{mainline} and +\cs{hidemoves} calls the move parser, \cs{variation} uses only the +PGN parser. + +The main difference between \packagename{xskak} and +\packagename{skak} is how they handle the information gathered by +the move parser: \Skaksty uses the results of the move parser mainly +to update the board and after the move throws almost all other +information away -- including previous positions. \xskak saves all +information about the moves for later use. Here a simple example: + +\begin{LTXexample} + \newchessgame + \mainline{1. e4 e5 2. Nf3 Nc6 3. Bb5 a6 4. Ba4 Nf6} + + \xskakset{moveid=2w}% + \chessboard[setfen=\xskakget{nextfen}]\\[1ex] + Position after 2.\,\xskakget{lan} +\end{LTXexample} + +So in short you start a game with \cs{newchessgame}, you enter moves +with \cs{mainline} (or \cs{hidemoves}), you set the move for which +you want to retrieve data with \cs{xskakset}, and then you retrieve +the data with \cs{xskakget}. + + +The storing of the moves and positions is not restricted to the main +game. You can store and retrieve as much variation levels you want. + + +\minisec{Printing styles} + +The following example shows how to use different styles for different +variation levels. But it also shows the problems: It can be quite +tiresome to get a good printing result. You must pay attention to the +levels and the spaces after commands, and for each variation you have +to start a new game and resume older games if you go back to them. + +\begin{LTXexample} +\longmoves \xskakset{style=UF} +\newchessgame[id=main] +\mainline{1.e4 e5} +% + (Alternatives are + \newchessgame[newvar=main,id=var1]% + \mainline[invar]{1... d5} which is answered by + \mainline{2. exd5 Qxd5} + % + \newchessgame[newvar=var1,id=var1-1] + (\mainline[invar]{2... Nf6}) + % + or + \newchessgame[newvar=main,id=var2] + \mainline[outvar]{1... e6 2. d4}) +% +\resumechessgame[id=main]% +\mainline[outvar]{2.Nf3} + +\chessboard +\end{LTXexample} + + + +\bigskip + +In the following sections I will describe the finer points. This +includes +\begin{itemize} +\item how to handle more than one game at a time, +\item how to retrieve the data faster, +\item what data you can retrieve, +\item how to loop through a game, +\item how to export the data, +\item how to improve the printing of the games, +\item and some other changes/additions I made to \packagename{skak}. +\end{itemize} + + +\subsection{Warnings} + +\minisec{\packagename{xskak} and \packagename{skak}} + +\Xskak doesn't only define some new commands, it also changes some +quite central internal commands of \skaksty. This means +\begin{itemize} + \item it can break standard commands of \skaksty, + + \item it will possibly not work together with future versions of + \skaksty, + + \item loading \packagename{xskak.sty} can lead to problems with + packages like \packagename{texmate} which use internally + \packagename{skak}. +\end{itemize} + +\minisec{Local and global commands} + +In the package \packagename{chessboard} almost every setting is local +to the board. This was a quite natural decision as a board is a +confined space. In \packagename{xskak} the situation is quite +different: As a start \packagename{skak} already sets and saves some +information globally and the data saved by \packagename{xskak} +during the parsing must be saved globally or they wouldn't never +escape the \cs{mainline}. And secondly, as I wanted to use +\packagename{beamer} and \packagename{animate} a lot of data +must be preserved from one frame/picture to the next. So I decided to +use in most cases global commands unless -- like in the cases of +styles -- I could see a real advantage in keeping a setting local. + +So please be aware that settings made e.g. in a figure environment +can affect the following text. + + +\subsection{Some history} + +While the commands \cs{mainline} and \cs{hidemoves} parse a chess +game \skaksty updates an internal board and so can always show the +current position. Sadly a lot of the data gathered during the +parsing are thrown away after \packagename{skak} has updated the +board and has go on to the next move and so can not be used by the +user. E.g. there is no way to get the field a piece came from or to +store easily all positions of a game. + +Some years ago I tried to find out how to print a game in long +algebraic notation and I realized quite fast that I need some of +these lost data to be able to do it, and that it would be necessary +to patch some internal commands of \skaksty to save the data. At the +same time I also tried to insert some code that allows the parsing of +standard PGN-comment signs. Due to lack of time the whole project +didn't got very far but I had a working beta. Then a new version of +\skaksty came. It had even a -- sadly at the time not fully working -- command \cs{longmoves}% + \index{longmoves=\verb!*+\longmoves+>}% + \index{shortmoves=\verb!*+\shortmoves+>} +(and the counterpart \cs{shortmoves}) to switch to the long algebraic +notation. But I hadn't the time to test and adjust my package. + + \index{longmoves=\verb!*+\longmoves+>}% + \index{shortmoves=\verb!*+\shortmoves+>}% + +Then in 2006 I wrote \pchessboard and during the tests also tried to +make animated pdf's which show all positions of a game. That worked +fine but the input was so tiresome that I restarted the +\packagename{xskak}-project: Like in the case of the long algebraic +notation the main problem was the loss of previous positions. + + +\subsection{Bugs and errors} + +I'm quite sure that they are bugs and errors in the package. + +If you have questions ask them in the newsgroups +\nolinkurl{comp.text.tex}, \nolinkurl{de.comp.text.tex} or +\nolinkurl{fr.comp.text.tex} or at \url{http://tex.stackexchange.com/}. +I'm reading these groups regularly and +I'm much better in answering there than in answering e-mails. + +If you find errors in this text (this includes wrong english) or in +the package, you can write me a bugreport at +\nolinkurl{chess@nililand.de} or -- better -- add an issue to the github site +\url{https://github.com/u-fischer/xskak/issues/}. A bugreport should contain a complete, +running, \emph{minimal} example and the log-file of the pdf\LaTeX\ +run (that means the engine that makes a pdf!). + + +\subsection{Requirements} + +\Xskak uses some primitives of e\TeX. It needs version 1.4 or version +1.5 of \skaksty, a recent version of \chessfss (chess font selection) +and \packagename{xkeyval} (\textit{key=value}-syntax), version 1.5 of +\packagename{chessboard} (which in turns needs \packagename{pgf}) and +\packagename{xifthen}. + + +\subsection{Installation} + +Run \filetype{xskak.ins} through \LaTeX\ and then put the +\filetype{*.sty} where \LaTeX\ finds them. +(\path{<texmf>/tex/latex/xskak/} is a good place.) Update the +filename database. + + +\subsection{Loading and package options} + +Loading of the package is done with \verb+\usepackage{xskak}+. +Currently the package has only one option: \texttt{nopdfmatch}.% + \index{nopdfmatch (package option)} +The option will disable the use of the experimental \cs{pdfmatch} +used in the processing of the style levels (see section +\ref{sec:usestyles}). \packagename{xskak} will load \skaksty without +option (and won't pass options to it). So, if you want to load +\packagename{skak} with options, you must do it before loading +\xskak. + +\subsection{Adaption to \skaksty version 1.5} + +Above I warned that \xskak can break with newer versions of \skaksty. +When the version 1.5 of \packagename{skak} appeared +promptly a lot of things broke so I had to adapt and change my code. +Version 1.2 of \xskak will work with both versions of +\skaksty. + +In version 1.5 of \skaksty some fundamental things have changed. At +first \cs{longmoves} works now correctly, even as you can see for the +\cs{variation} command: + + +\LTXinputExample[label=ex:longmovesnew, + graphic={[trim=3cm 24cm 9cm + 4cm,clip]{skak-longmoves-test-new}}, + caption={The new + longmoves implementation of + \skaksty}]{skak-longmoves-test-new} + + +The more important change (from the point of my package) is that +\cs{variation} now parse the moves too (that's why it can show the +long algebraic notation). To achieve this the author of \skaksty, +Torben Hoffman, stores now the position before a move so that he can +go back to this position and start the variation from there. + +The main problem with this approach is that it imposes restrictions +on the move numbers of variations: All variations must start with the +move number of the last move in a \cs{mainline} command. So +separating two moves of a variation by some text is no longer +possible: + +\begin{lstlisting} + \documentclass{article} + \usepackage{skak} %=skak version 1.5 + \begin{document} + \newgame + \mainline{1.e4 e5 2. Nf3} + \variation{2. d3 d6} %works + \variation{2. c3} %works + and then + \variation{2...c6} %error + \end{document} +\end{lstlisting} + +To tell the truth, I'm not sure that this a very good idea. In any +case: \xskak overwrites the responsable definitions of \skaksty. With +\xskak \cs{variation} currently doesn't parse games (and so also +can't show moves in long algebraic notation -- if you want this you +will have to start with the commands described later in this +documentation a new game with another id). So the above example works +fine with \xskak. + + + + + +\subsection{The example} + +Almost all examples use as starting point a new game. But in some +cases the following position is used, which allows to show almost all +special cases (like enpassant, promotion, capture, castling, +ambiguous moves). The position is stored under the name «example» and +so can be retrieved e.g. with the key \key{restorefen=example} from +\packagename{chessboard} or the command +\lstinline+\restoregame{example}+ of the package +\packagename{skak}\footnote{One could also use key \key{tag} to +store the position and key \key{reffen} to retrieve it.}: + +\begin{LTXexample}[caption={The standard example position},width=.7\textwidth] + \newchessgame[id=example, + castling=Q, + setwhite={pa2,pc7,pg5,ph2,pe4, + ke1,ra1,bg4}, + addblack={pb4,ph7,pd5, + ke8,rh8,bh3,nf6,ne5}, + storefen=example]% + + \mbox{\Xskakexampleinitfen} + + \chessboard +\end{LTXexample} + + +\section{Improved parsing of comments}\label{sec:diagrams} + + \Skaksty can handle comments in the input if they follow +directly the move, if the commands are robust and if the spaces that +separate moves and numbers are not swallowed by a command. + +\LTXinputExample[label=ex:comments, + graphic={[trim=3cm 24cm 9cm + 4cm,clip]{skak-comment-test}}, + caption={comments in \skaksty}]{skak-comment-test} + + +This is quite okay for a few small comments in a small number of +games, but a bit tiresome if you want to handle a lot of games that +you have annotated with a chess application. The PGN export of such +games uses NAG's for short comments and curly braces for longer +comments. + + +With \xskak the commands \cs{mainline}, \cs{hidemoves} and +\cs{variation} now can parse NAG's and longer comments if the input +meet the following conditions: +%\end{document} +\begin{itemize} + \item There must be spaces between the moves, each NAG and the + comments. + + \item Text comments must be written as + \verb+\xskakcomment{+\meta{Text}\verb+}+% + \footnote{Braces are so frequent in \TeX\ that is simply not + possible to identify the comments simply by looking for a brace + -- at least not without a lot of complicated hacks.} + +\end{itemize} + +While parsing the comments the spaces before and between them will be +swallowed. If you want a space you must add it to the text. The +NAG's (\$1, \$2 etc) are translated following the definitions in +\filetype{xskak-nagdef.sty}. The list there is neither complete nor +definite. For quite a lot NAG's I hadn't the faintest idea what do. +I'm open for suggestions/corrections. + +There exist two «fake» NAG's: \$d and \$D. If used in a \cs{mainline} +or \cs{hidemoves} both will save the identification of the current +move in an internal list and print whatever they have been defined +to. (Currently \$D will print \cs{chessdiagramname} which is defined +as \verb+\ (Diagram)\ +, \$d is +empty). This can be used to refer to diagrams printed later.% + \footnote{It is not a accidental that there is a similar command + «\cs{toD}» in \packagename{texmate}.

Currently + about 30 commands for each halfmove is saved plus about 30 commands + for each game. A lot of games with individual game identifications + can use a lot of memory. But in practice that shouldn't be a problem + as it is seldom necessary to use a lot of different game + identifications.} +data about the moves and the state of the game while parsing +the game. + +There are two sorts of data: Information related to the game as a +whole (e.g. the names of the players and the start position) and +information related to the moves. Both type of information use a +\meta{GameId} in the names of the commands to identify the game they +are referring to, the move data use additionally a \meta{MoveId}. + +\begin{shaded} +\minisec{Exkurs 1} + +It is important to understand one difference between the use of +\meta{GameId} and \meta{MoveId}: There is only \emph{one} command +that holds the current \meta{GameId}. The \meta{GameId} is a concept +specific to \xskak. The current value \meta{GameId} is stored in a +command and will be used (and can be changed) by all the commands +that store information \emph{and} by all the commands that retrieve +information. So if you are parsing a game in bits you should be +careful to use the same \meta{GameId} for each part. + +On the other sides there are \emph{three} different places where move +data are set or used: \skaksty uses in \cs{mainline} and +\cs{hidemoves} a counter called «\texttt{move}» and a boolean to keep +track of the current move and player. \Xskak has two internal +commands which are used to set up the start moves of games and to +retrieve the stored move data, and \cs{chessboard} has two keys that +set move data in FEN's. This can be sometimes a bit +confusing. \Skaksty will not like it if its move counter is changed +while parsing a game, but it is normally not a problem to change the +\packagename{xskak} move commands e.g. to retrieve data about +previous moves -- as long as you don't use commands like +\cs{newchessgame} that affects also the \packagename{skak} move +counter. +\end{shaded} + + +\begin{shaded} +\minisec{Exkurs 2} + +In chess we speak quite as often about the last move and the last +position than about the next move and the next position: A position +can be described as the one \emph{after} the \emph{last} move, the +result of a move. But it can also be described as the one +\emph{before} the \emph{next} move. + +The keys and commands described later reflect this: Given a move +number you can access e.g. the position \emph{before} the move +through the key word \key{pastfen} and the position \emph{after} the +move through the key word \key{nextfen}. Given a \emph{tag} -- that +is a label between two moves, you can refer to the move +\textit{before} the tag through keys with the prefix \key{past} and +to the move \emph{after} the tag through keys with the prefix +\key{next}. + +In short: \key{past} looks back and \key{next} looks forward. + +The first position of a game and the first move have the prefix +\key{init}. The last position (after the last move) and the last move +have the prefix \key{last}. + +\end{shaded} + + +\subsection{Initialization of the game} + +\DescribeMacro{\newchessgame}% +When using \xskak you should start a new game with +\cs{newchessgame}\keyoarg{} instead of \cs{newgame}.

The user interface supports an unlimited +number of levels: Each style is a bundle of \emph{levels} where the +look on each level is describe by a \emph{style item}\index{style +item} and some optional commands.

An input like + \verb+\mainline{1. e4}+\verb*+ \variation{1.e5}+ will already insert a + space so avoid to insert another one through e.g. \key{opencommands}. + + +\item It is possible to open a group (with +\cs{begingroup}) or a environment in one command and close it in +another command. If you do this check carefully that you have +balanced groups in all four combinations of white/black opening and +ending the game! Check also if everything works if you have only one +move. + +\item You don't have to give a definition for all keys/commands. +Unused keys are set to empty. + +\item If you want to force a style (or a style item) to use the long +or the short algebraic notation you can add +\cs{longmoves}/\hspace{0pt}\cs{shortmoves} to \key{opencommands}. + \index{longmoves=\verb!*+\longmoves+>}% + \index{shortmoves=\verb!*+\shortmoves+>}% +\end{itemize} + + +\item[\meta{beforeNAG}=\meta{commands}, \meta{beforecomment}=\meta{commands}] + +\packagename{xskak} puts around each NAG and comment given by +\cs{xskakcomment} a group and before each NAG's and comment a +formatting command.

If you e.g. want sometimes to add braces +through \key{opencommands} you could define variants $n$a, $n$b etc +of the involved variation level. + + + +\item While it is easy to define style items and styles it is not +easy sort and bundle them in a sensible way. + +\end{itemize} + + +\subsection{Using the styles}\label{sec:usestyles} + +The names of the commands \cs{mainline} and \cs{variation} give the +impression that you should use the first for the main game and the +second for the variations. But at my opinion this impression is +wrong: You should use + \begin{itemize} + \item \cs{mainline} if you want to parse \emph{and} print chess moves, + \item \cs{variation} if you want only to print chess moves, + \item \cs{hidemoves} if you want only to parse moves and + \item \cs{printchessgame} (described later) if you want to + (re)print a previously parsed game. + \end{itemize} + +This means that each of the printing commands can be used for the +main game and for variations.

One of the +problems that prevents better solutions is that there is no clear +description what should be the result of a conversion from PGN to +\LaTeX. In this section I will make some remarks about what I think +would be a good output from such a converter for +\packagename{xskak}\footnote{\packagename{texmate} needs another +output.} and where I see problems. The description should also help +you to enter or convert complicated games manually. + + +\minisec{The PGN-infos} + +The «tag pair» section of a chess game in PGN shouldn't pose problems +to a converter. The tags should be simply converted to the equivalent +keys of a \cs{newchessgame}: + +\begin{lstlisting} + [Round "29"] + [White "Fischer, Robert J."] + [Black "Spassky, Boris V."] + [Result "1/2-1/2"] +\end{lstlisting} +% +\begin{lstlisting}[escapechar=/] + \newchessgame[id=/\meta{GameId}/, %see below + round={29}, + white={Fischer, Robert J.}, + black={Spassky, Boris V.}, + result={1/2-1/2}] +\end{lstlisting} + +\xskakset{style=UF}% +If the game use a \texttt{SetUp} and a \texttt{FEN} tag to set an +alternative starting position, the converter will have to extract the +start move from the FEN and set it with the key \key{moveid}. + +\minisec{The \meta{GameId}} + +While it is probably possible to give each game an unique +\meta{GameId} I don't think that it is sensible or really necessary. +I would suggest, that each game gets uses\\ +\verb+\newchessgame[id=main\xskakaddtoid,...]+ where +\cs{xskakaddtoid} is empty by default but can be redefined to allow +some automatic numbering. + +\minisec{The parsing command} + +As you will probably sometimes use \cs{mainline} and sometimes +\cs{hidemoves} it is probably best if the converter use an general +\cs{parsechessgame} which can be \cs{let} to both commands. + +\minisec{NAG's} + +Most NAG's don't need any special handling as \packagename{xskak} can +parse them. + +But some chess applications seems to put NAG's \emph{after} a move to +denote a symbol that should go \emph{before} the move. E.g. + \verb+1. e5 $142+ +% +should become \betteris\variation{1. e5}. + +Putting such symbols before a move number is in most cases only +possible at the start of a \cs{mainline} or \cs{variation} so the +converter will have probably to split the input and add the symbol +either directly or through a style. A converter will need a list of +all this special cases and good rules how to handle them. + + + + +\minisec{Long comments} + +Longer commands (in the PGN in curly braces) could be handled either +by adding a \cs{xskakcomment} at the begin of the comment or by +ending the parsing and starting it again after the comment. The first +method has the advantage that one can use styles to format to some +extend the comments (or gobble them) but can cause problems if the +comment contains something that isn't allowed in the argument of a +command. + +I think some real examples are needed to decide what is the best way. + + +\minisec{The content of long comments} + +I don't think that is possible to handle all possible contents +automatically and get a suitable result for \LaTeX. You will either +have to follow some rules while inputing the comments or tidy them up +later. + +But a converter will probably be able to identify moves like +\texttt{4.\,\,Nf3} and to surround them by suitable +\verb+\variation[style=...,level=...]{...}+. + +\minisec{Diagrams} + +Some chess applications let you put markers at places where you would +like to print a diagram. E.g. chessbase put +\texttt{Diagramm~\#}\footnote{I don't know if «Diagramm» is language +dependent. Probably yes.} in a comment. + +A converter should also be able to recognize such markers for +diagrams. But it is not easy to decide what should be done with this +markers. In some cases you would probably not want to print boards at +all. Sometimes the game should be interrupted and the diagram printed +directly. Sometimes it should float. And I recall that someone once +tried to put all diagrams in the order there were mentioned in the +margin. If such markers are used it is probably the best if the +converter sets a tag and sets one of the fake NAG's \texttt{\$D} and +\texttt{\$d}. Then \cs{printchessgame} and the list of diagrams could +be used to print the moves and the diagrams in the intended order +(but it will probably need some coding to get the right results). The +tag and the NAG should be move outside of the comment as the comment +isn't processed in all cases. + +\begin{lstlisting}[caption={Input and suggested output for diagram +markers}] + 10. c3 e5 $1 {Diagramm # Die energische und konsequente + Fortsetzung, Schwarz öffnet das Zentrum, um seine Figuren zu + aktivieren.} 11. h3 +\end{lstlisting} + +\begin{lstlisting} + \mainline{10. c3 e5\xskakset{tag=dia1} $d $1 + \xskakcomment{ Die energische und konsequente Fortsetzung, + Schwarz öffnet das Zentrum, um seine Figuren zu aktivieren. } + 11. h3} +\end{lstlisting} + + + + +\minisec{Variations} + +Here starts the real problems. Even if we forget for the moment the +parsing of moves and diagrams it is not easy to describe a suitable +output. The main problems come from the fact that styles and good +typesetting are involved: E.g. PGN code two variations in a row as +\texttt{(1...~e5) (1...~e6)}. But you would probably print this as +(\variation{1... e5}; \variation{1... e6}). + +So the converter will have to look ahead and use suitable «open», +«middle», «close» and «single» styles in the different combinations. + +If you make long analyzes you will probably want to use numbered list +for the variations -- but not every variation is so important that +it need its own number. In this case there must be a marker that +tells the converter to handle this variation differently. + +I haven't solved all this problems but I think that the following +code could be used as starting point for further discussion about a +\LaTeX-chess input\footnote{If one really wants to parse all +variations a better naming for the nodes is needed.}: + +\begin{lstlisting} + \newchessgame[id=main, ...] + \mainline{...} + %new var level + \newchessgame[newvar=main,id=var1a]% + \mainline[level=1open]{.....} + %same var level + \newchessgame[newvar=main,id=var1b]% + \mainline[level=1close]{....} + %new var level + \newchessgame[newvar=var1b,id=var2a]% + \mainline[level=2single]{....} + %% return to var1b: + \resumechessgame[id=var1b] + \mainline[level=1open]{....} +\end{lstlisting} + + +\minisec{Initialization and title} + +Until now I have only discussed the game itself. But you would +probably want to print titles, make table of contents and other +lists. So one should also add some generic commands or environments +like \verb+\begin{chessgame}+/\hspace{0pt}\verb+\end{chessgame}+ and +\verb+{\chessgameheader}+ to each game. + + + + + + +\section{Compability issues} +\subsection{\texorpdfstring{\packagename{xskak} and +\packagename{texmate}}{xskak and texmate}}\index{texmate} + +It will probably work fine to use both packages in one document. + +\cs{newchessgame} and \cs{resumechessgame} will both internally issue +a \cs{fenposition} command that will setup the games also for +\packagename{texmate}. This naturally means in return that both +commands interfere with \packagename{texmate}! + +You can't benefit of the extended input possibilities for NAG's and +comments. \packagename{texmate} has its own parsing method. + +Btw: If you are using \packagename{texmate} you should always indent +your input as the package doesn't recognize new lines as spaces. + +\subsection{\texorpdfstring{\packagename{xskak} and +\packagename{beamer}}{xskak and beamer}}\index{beamer} + +When making presentations with \packagename{beamer} you should +remember two things: First you can't use verbatim material or other +commands that relies on catcode changes in the +\texttt{frame}-environment or -command.
