Stretch xskak chessboard to the width of a multicol column (inside a twocolumn article itself)

Question

With the following code :

\documentclass[a4paper,twocolumn]{article}
\usepackage{xskak}
\usepackage{lipsum}
\usepackage{parskip}
\usepackage{multicol}
\begin{document}
\lipsum[5]
\begin{multicols}{2}
\chessboard[setfen=8/8/5K2/2p3Bk/2P1R3/8/8/8 b - - 0 1,tinyboard,margin=false,showmover=false]\footnotesize{\lipsum[1]}
\end{multicols}
\lipsum[5]
\end{document}

I get the following result :

I would like the chessboard to span the entire width of the column, and the text that follows not to bite into the a-h letters of the chessboard files...

I would also like the 1-8 rank numbers of the chessboard not to be shifted to the left but to be aligned with the left side of the column...

I have not managed to achieve this ... Your help is welcome! Thank you!

Answer 1

I am not sure that using a multicols environment inside a twocolumn layout is a good idea (and the package issues a warning, so I guess, you should be very careful), but you can actually make use of the good ideas from this nice answer to your previous question and do something like the following:

\documentclass[a4paper,twocolumn]{article}
\usepackage{xskak,adjustbox}
\usepackage{lipsum}
\usepackage{parskip}
\usepackage{multicol}
\renewcommand{\adjboxvtop}{1ex}
\begin{document}
\lipsum[5]
\begin{multicols}{2}
  \begin{minipage}[t]{\linewidth}
    \hfill%
    \adjustbox{width={\linewidth-0.5em},valign=t}{%
      \chessboard[%
        setfen=8/8/5K2/2p3Bk/2P1R3/8/8/8 b - - 0 1,
        tinyboard,
        margin=false,
        showmover=false
      ]}%
  \end{minipage}\par%
  \footnotesize
  \lipsum[5]
\end{multicols}
\lipsum[5]
\end{document}
