But somehow I got frustrated. I forget exactly what it was, but it frustrated me. It was about annotating the games, somehow the syntax requirements that \textsf{skak} imposed were too cumbersome when an analysis had many variations and subvariations. + +So I simply didn't do it in \TeX---I think I didn't do it at all. Until one day I got a game that I wanted to publish. So I went to Word---yes, yes, I'm sorry, but I had no option. Besides, the editors of the \emph{Pennswoodpusher} certainly used Word, so a Word file would be better. + +I commented my game, and `translated' it into a more readable format to send it to my friends. I wanted figurines instead of initials for the pieces (I used a True~Type for this), I wanted the main game to be separated from the commentary by paragraph breaks, sub-variations to be indicated differently, etc. The contents of the game, and even the analyzed variations, were of course the same. I started looking at several books to see their chess-formatting habits. + +And I figured that being able to transcribe a game from format to format without having to edit the input is, clearly, a task for \TeX\dots + +\TeX mate is the result. The emphasis is on the formatting of annotated games of chess. \textsf{skak}'s focus seems to be more graphical: beautiful tools for diagrams (the package itself even keeps track of the position according to the moves in the game---which of course is the deep reason why it's not really flexible about variations and alternative lines---those confuse it). + +Commented code is in the file \texttt{texmate.dtx}. A user's manual required using the package, so it comes as this one separate file. + +\section{A note on installation} +Installation is straightforward: the packages is made of a `source' (\texttt{texmate.dtx} and \texttt{texmate.ins}), which generate a `tex' (\texttt{texmate.sty}) and a `doc' (\texttt{texmate.dvi}) with the commented code. In addition, there is this extra `doc,' \texttt{texmatesample.tex}. + +But the fonts of the \textsf{skak} package have to be installed. The easiest would of course install \textsf{skak} itself. I have included the fonts. There are \texttt{.mf} files (`source'), \texttt{.fd} files (`vf') and a \texttt{.map} file. + +\section{Basic conventions} +The moves are input with the (short) algebraic system of notation. + +\begin{description} +\item[Pieces] Default is English piece initials (Rook, kNight, Bishop, Queen, King). But this can be changed with \verb"\pieceinitials"\DescribeMacro{\pieceinitials}. In fact, \TeX mate itself uses this command to initialize the default: \verb"\pieceinitials{PRNBQK}". The argument is the initials to be used, respectively, for pawn and then left to right in White's initial position. The initial for pawn is given only for diagrams---in game notation the pawn is not indicated. + +\item[Move Numbers] \TeX mate keeps track of the move number. Inputting the numbers is totally optional to the user, and although it may be helpful for later edition of the document, sometimes the variations and sub-variations are so complicated that one loses track of them. If the user does indeed input the number, it will override \TeX mate's count. + +\item[Delimiters] Moves (and move numbers) are delimited by spaces, periods, or semicolons. None of these will be typeset directly, since \TeX mate takes care of all formatting and punctuation. Of course, this is customizable. + +\makebarother +\item[Chess mode] All this is done within `chess mode:' just as \verb"$" changes to math mode, \verb+|+ changes to chess mode. Sometimes (notably tables) you need \verb"|" for other things, so you can turn its chess meaning off with \DescribeMacro{\makebarother}\DescribeMacro{\makebarchess}\verb"\makebarother". To turn it back on, \verb"\makebarchess". + +\item[Checks] should be input (with \verb"+"), even if you don't like them to be typeset. There is a \verb"\checksign" command (default `\checksign') that you could redefine as nothing. + +\item[Captures] too should be input, with \verb"x", even if not intended to be visible. The command \verb"\takes" holds the sign that will be used for them (default a space-trimmed \verb"\times"). + +\item[Mate] is done through \verb"\mate". Alternatively, of course, \verb"\#". + +\item[Promotions] are kind of an exception. Due to how \TeX mate works, the particle `\verb"c8N"' will produce literally `c8N,' instead of `c8\knight.' I did not think it was worth to change the whole nature of the system just for this, so I will ask the user to use piece-name commands for promotions: `\verb"c8\knight"' (or `\verb"c8=\knight",' as some people do). +\end{description} + +\makebarchess +\section{Formatting and punctuation} +The output will be consistent as to punctuation marks. All of the following input streams:\makebarother + +\verb"|1. e4 e5; 2. Nc3 Nf6; 3. Bb5 a6|", + +\verb"|1 e4 e5 2 Nc3 Nf6 3 Bb5 a6|", and even + +\verb"|1 e4 e5 Nc3 Nf6 ; Bb5 a6|", + +\noindent will produce, with default settings, \makebarchess`|1 e4 e5 2. Nc3 Nf6; 3 Bb5 a6|.' This format can be changed redefining the following commands: + +\makebarother +\begin{center} +\begin{tabular}{|lp{.8\textwidth}|}\hline +\verb"\afterno" & What comes after the number (\verb".~" by default)\\ +\verb"\afterw" & What comes between white's and black's moves (\verb*" ")\\ +\verb"\afterb" & What comes between black's move and the next number (\verb*"; ")\\ +\verb"\beforeb" & What comes before black's move when it's resuming the variation (\verb*"\the\move.\ \dots~")\\ +\verb"\beforeno" & What comes before the number.\\\hline +\end{tabular} +\end{center} +\makebarchess + +The character that symbolizes each pieces (by default the figurines) is contained in the commands \verb"\rook", \verb"\knight", \verb"\bishop", \verb"\queen", and \verb"\king", and can be changed at any moment. These piece-name commands, as well as those for chess symbols, can be used in running text. Or in chess mode, for that matter. + +\section{Commentary} +Within chess mode, the character \DescribeMacro{[}\DescribeMacro{]}\verb"[" opens a commentary. \TeX mate will then expect a move that is an alternative to the one in the text. For example: + +\makebarother +\verb"|34. Nd5? [Ne4!] Bxd5! [Qxd5? 35. Re1!\wBetter]|" +\makebarchess +\newgame + +|34. Nd5? [Ne4!] Bxd5! [Qxd5? 35. Re1!\wBetter]| + +\smallskip + +Commentaries can be nested: + +\makebarother +\verb"|35. Re1 [cxd5?! Qxd5 [Kh8? dxc6\wbetter [c3!?]]\; Kh1]|" +\makebarchess + +|35. Re1 [cxd5?! Qxd5 [Kh8? dxc6\wbetter [c3!?]]\; Kh1]| + +\smallskip +As you see, \TeX mate takes care of punctuation and fonts. But before going about modifying \DescribeMacro{\[}\DescribeMacro{\]}this things, there is an alternative way of commentary: \emph{control~sequences} \verb"\[" and \verb"\]". They are intended for freer commentary: they do not insert any punctuation, and the user has total control over the way the commentary is typeset. + +\DescribeMacro{\ifont}\DescribeMacro{\iifont}\DescribeMacro{\iiifont}\DescribeMacro{\ivfont}All of this can be modified. The samples that follow later in this document are probably the best way to learn about this. But here is the abstract explanation: the main game (boldface by default) is `level' 1. There are 4 levels, and their fonts are controlled by \verb"\ifont", \verb"\iifont", \verb"\iiifont", and \verb"\ivfont". They can be defined as standard commands like \verb"\bfseries", but there's one caveat: this doesn't apply by itself to the chess font. Changing levels 3 and 4 is easy; for levels 1 and 2, look at the code of \TeX mate. + +\DescribeMacro{\iopen}\DescribeMacro{\iclose}\DescribeMacro{\iiopen}\DescribeMacro{\iiclose}\marginpar{\hfill$\vdots$\quad\null}The symbols that mark the opening and closing of the commentaries are typeset by the commands \verb"\iopen", \verb"\iclose", \verb"\iiopen", \verb"\iiclose", etc. These are called by the characters \verb"[" and \verb"]". The control sequences \verb"\[" and \verb"\]" call for \verb"\iopent", \verb"\icloset", etc.\ (`\verb"t"' for `text'). If you are going to change these, remember that the first level of commentary is level~2 (1 is the game itself). + +Text can be inserted in commentaries, simply by using the \makebarother\verb"|" character properly. Examples in the next sections illustrate. + +\subsection{Additional commenting tools} +\DescribeMacro{\dummy}\DescribeMacro{\ddummy}With \verb"\dummy" and \verb"\ddummy" you can insert `dummy' moves. If \TeX mate was expecting White's move number 32, \verb"\dummy" will make it expect Black's move number 32 (half a move is skipped). With \verb"\ddummy", it will expect White's move number 33 (a entire move was skipped). Remember that you can change the move number at any moment simply by typing the new number in the input. + +\DescribeMacro{\white}\DescribeMacro{\black}With \verb"\white" you force \TeX mate to handle the next move as one by White. \verb"\black" forces it to handle it as one by Black. With these commands, \TeX mate does not try to keep track of the move number, and so they should be used in connection with numbers. Both \verb"| 34 \black| " and \verb"|\black 34|" work in the same way: \TeX mate will expect Black's move number 34. + +\DescribeMacro{\steplevel}\DescribeMacro{\backlevel}If you want to use the fonts of another level without actually invoking a commentary, you can use \verb"\steplevel" and \verb"\backlevel". The former increases the level by 1, the latter decreases it by 1. Both then load the corresponding font for the level. + +Remember that the main game is level 1, the last level of commentary is level 4. + +\DescribeMacro{\threat<...>}With the \verb"\threat" macro you can introduce threats. This command has an argument, enclosed within \verb"<" and \verb">"; the argument is set \emph{as regular text} (i.e., not in chess mode). Before it, though, the sign \withidea\ is appended. For example: + +\verb"|17. Nce5!\threat<h4!\wBetter\attack> Ne8! h4? f5!|" + +\makebarchess +|17. Nce5!\threat<h4!\wBetter\initiative> Ne8! h4? f5!| +\makebarother + +\section{Diagrams} +Producing the diagrams is really straightforward, more so than trying to explain it in words. Here are two examples that should make it really clear already: + +\noindent\diagram{r1r1k/pp1qn2p/5pp/3p2N/% +6Q/8/PP3PPP/2R1R1K}\hfill{\pieceinitials{PTCADR}\diagram{t4tr/1d2ppap/a2p2p/2pc//1P4P/P3PPAP/1TADTCR}} +\begin{verbatim} +\diagram{r1r1k/pp1qn2p/5pp/3p2N/% \diagram{r4rk/1q2ppbp/b2p2p% + 6Q/8/PP3PPP/2R1R1K} 2pn//1P4P/P3PPBP/1RBQRNK} +\end{verbatim} + + + +\DescribeMacro{\diagram}The diagram is typeset from the top board file to the bottom one, and from left to right. Numbers mean consecutive empty squares; lowercase letters mean black pieces; uppercase letters are white pieces. \verb"/" finishes a line. \TeX mate will fill any empty squares at the right of the last piece in the file. + +For the pieces you use the letters defined by \verb"\pieceinitials" (default \texttt{PRNBQK}). + +\DescribeMacro{\diagramsize}The default size for the diagram (each of its squares) is 18pt. It can be changed modifying the \LaTeX\ length \verb"\diagramsize". + +\DescribeMacro{notfilling}The diagrams don't have to be $8\times8$. If you choose the \texttt{notfilling} option to \TeX mate, it will not fill up the remaining squares in incomplete files, so you can have $4\times4$ boards, for example. The \DescribeMacro{\SquareNo} \verb"\SquareNo" variable holds the number of squares per line, and it can be modified. + +\section{Samples} + +The following are examples from real life. Modifying a few commands, I was able to mimic the formats of two books, and I present a game from each. Looking at the code for these samples must be the best way to learn how to use \TeX mate. + +\subsection{A famous study} +But first comes a beautiful position. I used almost the default formatting of \TeX mate, except redefining +\begin{verbatim} +\renewcommand\afterb{ } +\renewcommand\iiclose{\leavevmode\unskip] } +\end{verbatim} +\noindent so that there is no semicolon between black and white moves. I chose this because there are alternatives in the text-scarce commentaries, and they are separated by ;. + +\newgame +\bigskip +\centerline{\diagram{8/8/1KP/3r/8/8/8/k}} + +\medskip +This position has been associated to the name of a Spanish amateur, Saavedra. Its history is interesting: it seems that a similar endgame was reached in a game toward the end of the 19\textsuperscript{th} century, and called a lot of attention. Zukertort published an analysis of it---almost complete, but not quite. And then it was left to Saavedra to find, while reading Zukertort's article, a move that must be counted among the most amazing chess tricks to be found anywhere. + + +\renewcommand\afterb{ } +\renewcommand\iiclose{\leavevmode\unskip] } +\makeatletter +\makebarchess +\newgame +|1. c7 Rd6+\onlymove 2.
