Fix the postion of tikzpicture

Question

I have a trouble in fixing the position of a tikzpicture when there is overlay. In the example, due to the overlay of the texts below the picture, the picture will float a bit. However, I would like the picture to be fixed at the exact position, such that when I scroll the pages the effect looks like only the text is changing but the picture doesn't move at all.

Here is my example:

\documentclass[10pt,xcolor={dvipsnames}]{beamer}
\usepackage{tikz}
\begin{document}
    \begin{frame}{title}
        \begin{center}
            \begin{tikzpicture}
                    \tikzset{
                round node/.style={circle,draw,inner sep=1.5}
                                    }
                \node [round node] (1) {1};
        \end{tikzpicture}
        \end{center}
\begin{itemize}
    \only&lt;1&gt;{ \item By convention, we do not draw the information sets that contain a single node
        \item Therefore, any uncircled (or unlinked) decision node should be understood as a \textbf{singleton} information set}
    \item&lt;2&gt; In Figure (b), \textbf{player 2 has two singleton information sets}:
    \begin{itemize}
        \item The left one: player 2 knows that player 1 has chosen H
        \item The right one: player 2 knows that player 1 has chosen T
    \end{itemize}
\end{itemize}
\end{frame}

\end{document}

Remark: I don't use \uncover or \onslide because I don't want to leave blank space.

The easiest way to avoid any potential jumping is to use a top aligned frame:

\documentclass{beamer}
\usepackage{tikz}
\begin{document}
\begin{frame}[t]{title}
    \begin{center}
        \begin{tikzpicture}
                \tikzset{
            round node/.style={circle,draw,inner sep=1.5}
                                }
            \node [round node] (1) {1};
    \end{tikzpicture}
    \end{center}

\begin{itemize}
    \only&lt;1&gt;{ \item By convention, we do not draw the information sets that contain a single node
        \item Therefore, any uncircled (or unlinked) decision node should be understood as a \textbf{singleton} information set}
    \item&lt;2&gt; In Figure (b), \textbf{player 2 has two singleton information sets}:
    \begin{itemize}
        \item The left one: player 2 knows that player 1 has chosen H
        \item The right one: player 2 knows that player 1 has chosen T
    \end{itemize}
\end{itemize}
\end{frame}

\end{document}

Alternatively, you could use an overlayarea of suitable height:

\documentclass{beamer}
\usepackage{tikz}
\begin{document}
\begin{frame}{title}
    \begin{center}
        \begin{tikzpicture}
                \tikzset{
            round node/.style={circle,draw,inner sep=1.5}
                                }
            \node [round node] (1) {1};
    \end{tikzpicture}
    \end{center}

\begin{overlayarea}{\textwidth}{.5\textheight}
\begin{itemize}
    \only&lt;1&gt;{ \item By convention, we do not draw the information sets that contain a single node
        \item Therefore, any uncircled (or unlinked) decision node should be understood as a \textbf{singleton} information set}
    \item&lt;2&gt; In Figure (b), \textbf{player 2 has two singleton information sets}:
    \begin{itemize}
        \item The left one: player 2 knows that player 1 has chosen H
        \item The right one: player 2 knows that player 1 has chosen T
    \end{itemize}
\end{itemize}
\end{overlayarea}
\end{frame}

\end{document}

Wow, it is so cool!! I have tried dozens of super complex methods and none of them worked. Didn't expect such an easy solution. Thank you very much!!!! — PiHal, Apr 12 '23 at 11:23
The second solution is even better! Because my actual tikzpicture is more complex, if I use top aligned frame, the position still changes a bit. But the second approach completely solved my problem. Thanks again! — PiHal, Apr 12 '23 at 11:32
