rank formating not optimal when setting peculiar boards.

[Karpeth]

Tamerlane chess and others require some weird things to typeset.

The following is what I use.

\def\timurfile{\ifthenelse{\equal{\value{filelabel}}{12}}{}{\alph{filelabel}}}
\def\nyrank{\hfill\makebox[0pt][r]{\arabic{ranklabel}\hspace{1ex}}}
\chessboard[%hlabelformat=\nyrank,
margin=false,smallboard,vlabelformat=\timurfile,border=false,zero=true,pgfstyle=color,color=white,markregion={Z2-Z8,Z10-Z10, `l4-l10},pgfstyle=border,markregion={Z1-l10},maxfield=m10,printarea={Z1-l10},pgfstyle=bottomlefttopborder,linewidth=0.04em,color=black,markregion={Z9-Z9},pgfstyle=leftborder,markregion={a2-a8},pgfstyle=rightborder,markregion={k3-k9},pgfstyle=toprightbottomborder,markregion={l2-l2},pgfstyle=lefttoprightborder,markregion={a10-k10},pgfstyle=rightbottomleftborder,markregion={a1-k1},pgfstyle=toprightbottomborder,markregion={l2-l2},showmover=false,%addpieces={Ea1,Ek1,ea10,ek10,Ra2,Rk2,ra9,rk9,Nb2,Nj2,nb9,nj9,Fe2,Kf2,Vg2,fg9,kf9,ve9,Gd2,Gh2,gd9,gh9,Cc1,Ci1,cc10,ci10,De1,Dg1,de10,dg10,Hc2,Hi2,hc9,hi9,Ia3,ik8,Jb3,jj8,Lc3,li8,Od3,oh8,Se3,sg8,Tf3,tf8,Ug3,ue8,Wh3,wd8,Xi3,xc8,Yj3,yb8,Zk3,za8}
]`
\end{minipage}\begin{minipage}[t][][b]{.5\textwidth}

without nyrank, the ranks gets overwritten by a blank white square. timurfile (and others in the project) surpresses the letters at 0 and the final square.

It would be nice not to work around the package. :)

You have a very short memory: https://github.com/u-fischer/chessboard/issues/11#issuecomment-1934143627 I'm closing this as unclear.

I am sorry.

Here including my code, with the preamble.

\documentclass[titlepage,a4paper,oneside]{report}
\usepackage{chessboard}
\begin{document}
\def\timurfile{\ifthenelse{\equal{\value{filelabel}}{12}}{}{\alph{filelabel}}}
\def\nyrank{\hfill\makebox[0pt][r]{\arabic{ranklabel}\hspace{1ex}}}
\chessboard[%hlabelformat=\nyrank,
margin=false,smallboard,vlabelformat=\timurfile,border=false,zero=true,pgfstyle=color,color=white,markregion={Z2-Z8,Z10-Z10, l4-l10},pgfstyle=border,markregion={Z1-l10},maxfield=m10,printarea={Z1-l10},pgfstyle=bottomlefttopborder,linewidth=0.04em,color=black,markregion={Z9-Z9},pgfstyle=leftborder,markregion={a2-a8},pgfstyle=rightborder,markregion={k3-k9},pgfstyle=toprightbottomborder,markregion={l2-l2},pgfstyle=lefttoprightborder,markregion={a10-k10},pgfstyle=rightbottomleftborder,markregion={a1-k1},pgfstyle=toprightbottomborder,markregion={l2-l2},showmover=false,%addpieces={Ea1,Ek1,ea10,ek10,Ra2,Rk2,ra9,rk9,Nb2,Nj2,nb9,nj9,Fe2,Kf2,Vg2,fg9,kf9,ve9,Gd2,Gh2,gd9,gh9,Cc1,Ci1,cc10,ci10,De1,Dg1,de10,dg10,Hc2,Hi2,hc9,hi9,Ia3,ik8,Jb3,jj8,Lc3,li8,Od3,oh8,Se3,sg8,Tf3,tf8,Ug3,ue8,Wh3,wd8,Xi3,xc8,Yj3,yb8,Zk3,za8}

\end{document}

ranks above 10 will not play nice unless the alignment is changed, as with nyrank.

You are not working around the package. The default settings are for normal 8x8 chessboards. If you setup a weird board you have to adapt the settings, and the keys hlabelformat and vlabelformat etc are provided for this.
