章节标题中的特殊内容

Question

我正在尝试使用 skak 国际象棋包设置一篇文章，并在章节标题中包含符号：

\documentclass[a4paper]{article}
\usepackage{skak}
\begin{document}
    \section{Open Games (\newgame\mainline{1.e4 e5})}
\end{document}

这给出了一长串错误列表，首先是Undefined control sequence. ...on{Open Games (\newgame\mainline{1.e4 e5})}

我知道标题适用特殊规则，但我不明白它们——如何将符号放入章节标题中？（我知道在这种情况下我不需要 skak，因为生成的符号看起来就像纯文本，但情况并非总是如此，有时它会涉及棋子的符号。而且 skak 对移动的有效性的检查也很有用——我第一次输入它时输入了 1.e4 44。）

编辑-根据 DG' 的回答，我的新 MWE 是：

\documentclass[a4paper]{book}
\usepackage{xskak}
\usepackage[inline]{enumitem}
\begin{document}
    \chapter{First Group}
    \section{Open Games (\protect\newchessgame\mainline{1.e4 e5})}
    \subsection{Centre Game}
    (\newchessgame\mainline{1.e4 e5 2.d4})
    
    \newchessgame\styleC\mainline{1.e4 e5 2.d4 exd4 3.Qxd4 Nc6 4.Qe3     Nf6\wbetter}\storegame{centregame1}
    
    \begin{enumerate}
        \item \mainline{5.e5 Ng4 6.Qe4}
        \mainline{6...d5 7.exd6 Be6 8.dxc7 Qd1+ 9.Kxd1 Nxf2 10.Ke1     Nxe4}
        \item \restoregame{centregame1}\mainline{5.Nc3 Bb4 6.Bd2 O-O 7.O-O-O Re8 8.Bc4}\storegame{centregame2}

    \begin{figure}
        \centering
        \caption{Position after White's 8\textsuperscript{th} Move}
        \chessboard
    \end{figure}

    \begin{figure}
        \centering
        \caption{Position after White's 13\textsuperscript{th} Move}
        \chessboard
    \end{figure}

这会导致以下几个错误：

! LaTeX Error: Something's wrong--perhaps a missing \item.

See the LaTeX manual or LaTeX Companion for explanation.
Type  H <return>  for immediate help.

If that doesn't work, type  X <return>  to quit.

I've inserted something that you may have forgotten.
(See the <inserted text> above.)
With luck, this will get me unwedged. But if you
really didn't forget anything, try typing `2' now; then
my insertion and my current dilemma will both disappear.

! Missing } inserted.

如果我将棋步从标题移开，问题就会消失 - 但公平地说，如果我改变几乎任何其他东西，包括删除一些 lorem ipsum 文本，问题仍然会消失，所以我不再确定问题出在哪里。

在这种情况下，使用xskak代替skak并保护命令是\section可行的。但我不知道它是否适用于更复杂的游戏。

\documentclass[a4paper]{article}
\usepackage{xskak}
\begin{document}
    \section{Open Games (\protect\newgame\mainline{1.e4 e5})}
    \section{Open Games 2 (\protect\newgame\mainline{1. e4 e5 2. Nf3 Nc6 3. Bb5 a6 4. Ba4 Nf6})}
\end{document}

如果您想使用hyperref，您可能需要编写如下包装器：

\documentclass[a4paper]{article}
\usepackage{xskak}
\usepackage{hyperref}

\DeclareRobustCommand\GameLine[1]{%
    \texorpdfstring{\newgame\mainline{#1}}{#1}}

\begin{document}
    \section{Open Games (\GameLine{1.e4 e5})}
    \section{Open Games 2 (\GameLine{1. e4 e5 2. Nf3 Nc6 3. Bb5 a6 4. Ba4 Nf6})}
\end{document}
