Equivalent of pstricks command \psecurve in tikz

Question

What is the equivalent of the pstricks command \psecurve in tikz?

The yellow line is the \psecurve. It's basically the same as the \pscurve: the curve is defined by all the named points, but is not drawn to the end points.

\documentclass{article}
\usepackage{pstricks}
\pagestyle{empty}
\begin{document}

\begin{pspicture}(0,-3)(5,5)
   \pscurve[linewidth=5pt,arrows=<->](0,0)(2,3)(4,-3)(2,5)(1,0)
  \psecurve[linewidth=1.5pt,linecolor=yellow](0,0)(2,3)(4,-3)(2,5)(1,0)
\end{pspicture}

\end{document}

Answer 1

You can use my style between style (from TikZ: Thick curve segment in a curve):

\documentclass[margin=2mm]{standalone}
\usepackage{tikz}
\usepackage{ifthen}
\usetikzlibrary{decorations.pathreplacing,decorations.markings}
\newcounter{pos}
\tikzset{
  initcounter/.code={\setcounter{pos}{0}},
  style between/.style n args={3}{
    postaction={initcounter, decorate,
      decoration={show path construction, curveto code={
          \addtocounter{pos}{1}
          \pgfmathtruncatemacro{\min}{#1 - 1}
          \ifthenelse{\thepos < #2 \AND \thepos > \min}{
            \draw[#3]
            (\tikzinputsegmentfirst) .. controls
               (\tikzinputsegmentsupporta) and (\tikzinputsegmentsupportb)
            .. (\tikzinputsegmentlast);
          }{}
        }
      }
    },
  },
}
\begin{document}
\begin{tikzpicture}[line join=round]
  \draw[line width=5pt,<->]
  (0,0) to[out=70,in=180] (2,3) to[out=0,in=180] (4,-3)
  to [out=0,in=0] (2,5) to[out=180,in=100] (1,0);

  \path [style between={2}{4}{line width=1.5pt,yellow}]
  (0,0) to[out=70,in=180] (2,3) to[out=0,in=180] (4,-3)
  to [out=0,in=0] (2,5) to[out=180,in=100] (1,0);
\end{tikzpicture}
\end{document}
