如何在不同框架的 LaTeX 投影机中添加棋盘图 \xskakloop？

Question

\documentclass[aspectratio=169]{beamer}
\hypersetup{pdfpagemode=FullScreen}
\renewcommand{\familydefault}{\rmdefault} 
\usepackage{tikz}

\usepackage[LSB2,LSBC4,T1]{fontenc} % use fontenc before chessboard
\usepackage{skak,xskak,chessboard,texmate}
\setbeamertemplate{navigation symbols}{}
\makeatletter
\providecommand\xskak@beforecomment{} %ups a bug, definition is missing
\makeatother

\begin{document}
\newcommand\getmovestyle[1]{%
\ifthenelse
{\equal{#1}{N}}%knight move
{\def\mymovestyle{[clockwise=false,style=knight]curvemove}}%
{\ifthenelse
{\equal{#1}{}}% castling
{\def\mymovestyle{curvemove}}%
{\def\mymovestyle{straightmove}}}}%

\begin{frame}
\newchessgame
\mainline{1. e4 d5}\\  
\setchessboard{boardfontsize=19.7pt,labelfontsize=12pt,labelfont=\rmfamily,moverstyle=circle,restorefen=current}

 \setboardfontcolors{blackfieldmask=green!60}
 \xskakloop{%
 \getmovestyle{\xskakget{piecechar}}%
 \chessboard[boardfontencoding=LSBC4,  pgfstyle=\mymovestyle, color=blue!50, markmoves=\xskakget{move}, pgfshortenend=0.3em, arrow=to,     coloremph, color=red!50, markstyle=circle, markfield=\xskakget{movefrom},emphfields=\xskakget{moveto}, setfen=\xskakget{nextfen}]\\
\xskakget{opennr}
\xskakget{lan}
\xskakget{nag} 
\par            
 }
\end{frame}
\end{document} 

当我使用 \xskakloop 按顺序排版棋图时，它会向下移动而不是嵌入到 LaTeX 投影机的不同框架中。
