I'm quite new to LaTeX and I'm trying to replicate this using Tikz:

Possible ways to place 4 queens on a 4 x 4 chessboard

I know there is some chess-related things I can include, but it diesn't seems to be adapted for something like this.

\documentclass{book}

\usepackage[utf8]{inputenc}


\usepackage{tikz}


\begin{document}


\begin{tikzpicture}
\draw[xstep=0.75cm,ystep=0.5,color=gray] (0,0) grid (3,2);
\matrix[matrix of nodes,
inner sep=0pt,
anchor=south west,
nodes={inner sep=0pt,text width=.75cm,align=center,minimum height=.5cm}
]{
  & ♕ &   &    \
  &   &    & ♕ \
♕&   &    &    \
  &   & ♕ &    \
};
\end{tikzpicture}


\end{document}

This is my best attempt while trying to reproduce it. However this yield an error because the unicode character of the queen is not included in the utf-8 inputenc I guess, and I couldn't find how to include a special character or a picture in a Tikz grid...

I am not english and I am new to this forum, so the post might contain few mistakes. Sorry for the inconvenience, and thanks in advance for your help !

    Let's break it down. First, you need to use \DeclareUnicodeCharacter to declare that you are going to use the unicode character ♕ in your document. Say you map ♕ to a command \KelkunQueen. Then you want to define KelkunQueen to be a command that enters a tikzpicture and draws a queen. – Symbol 1 Jul 28 '21 at 21:00

So I finally found how to solve the problem after some additionnal searches on special characters. For anyone who would have the same problem, the package skak seems to be perfect:

\documentclass{book}

\usepackage{skak}
\usepackage{tikz}
\usetikzlibrary{matrix}


\begin{document}


\begin{tikzpicture}
\draw[step=0.5cm,color=gray] (-1,-1) grid (1,1);
\matrix[matrix of nodes,nodes={inner sep=0pt,text width=.5cm,align=center,minimum height=.5cm}]{
  & \symqueen &   &   \
  &   &   & \symqueen \
\symqueen &   &   &   \
  &   & \symqueen &  \};
\end{tikzpicture}


\end{document}

Thanks for the replies!

    \symqueen is provided by the chessfss package (which is loaded by skak), so \usepackage{chessfss} will work too. – Ulrike Fischer Jul 28 '21 at 21:20
