How to use the "mover" command in Skak

Question

I teach after school chess, and installed LaTeX on my computer just to make chess worksheets. I'm using skak.

My documents start:

\documentclass[12pt]{article}
\usepackage{chess-workshop-symbols}
\usepackage{skak}
\usepackage[margin=0.2in]{geometry}
\begin{document}

and then have the problems I want to give the kids, like so:

% one solution, three checks
\fenboard{5rk1/pp3N1p/4P3/2P5/3Q1PK1/P7/1Pr3pq/R3R3 w - - 0 0}
\showboard

I would love to have the worksheets show whether it is black's move or white, but I haven't been able to get the command \showmoverOn to work (nor \showmover or \moverOn or \mover). Any idea what I'm doing wrong?

When I try it, the console output says something like:

! Undefined control sequence.
\ShowMoverBlackNormal ->\pscustom 
                                  [fillstyle=solid,fillcolor=gray]{\skak@tra...
l.23 \showboard

? 

Answer 1

As kahen wrote, skak relies on pstricks for some of the "decoration". I suggest to use chessboard instead:

\documentclass{article}
\usepackage{chessboard}

\begin{document}
\chessboard[setfen=5rk1/pp3N1p/4P3/2P5/3Q1PK1/P7/1Pr3pq/R3R3 w - - 0 0,
            showmover]
\end{document}

If you want to print/parse moves you can use either skak or xskak, both will work together with chessboard. You don't need chess-workshop-symbols: the symbols it defines are nowadays defined by the chessfss package used internally from all the three packages.

My psychic debugging powers tell me that you're trying to compile your document with pdflatex. skak makes use of pstricks for drawing things, so you'll either need auto-pst-pdf or just compile with latex.
