FEN 中的星号符号

Question

如何在 FEN 符号中放入星号？我无法在 DiagTransfer 3.0.1 中做到这一点。

我写道（没有星号）：

\documentclass{article}
\usepackage[utf8]{inputenc}
\usepackage{xskak}

\begin{document}

\centering
\newchessgame[setfen=8/8/8/8/4K3/8/8/8 w - - 0 1]
\showboard

\end{document}

感谢 Ulrike Fischer！我做了这个：

\documentclass{article}
\usepackage[utf8]{inputenc}
\usepackage[LSB3,T1]{fontenc}
\usepackage{xskak}
\usepackage{chessboard}
\usepackage{mathabx}
\makeatletter
\cbDefineNewPiece{white}{C}
  {\raisebox{\depth}{\cfss@whitepiececolor
   $\bigstar$}}
  {\BlackEmptySquare%
   \makebox[0pt][r]{\cfss@whitepiececolor
   \raisebox{\depth}{%
   \makebox[1em]{$\bigstar$}}}}
\cbDefineNewPiece{black}{c}
  {\raisebox{\depth}{\cfss@blackpiececolor
   $\bigstar$}}
  {\BlackEmptySquare%
   \makebox[0pt][r]{\cfss@blackpiececolor
   \raisebox{\depth}{%
   \makebox[1em]{$\bigstar$}}}}
\makeatother

\begin{document}

\setchessboard{
  addpieces={},addwhite=Ke4,
  addblack={Cd3,Cd4,Cd5,Ce3,Ce5,Cf3,Cf4,Cf5},showmover=false}
\chessboard

\end{document}
