Problem
I would like the arrow in the diagram
to extend farther to the right, so that it doesn't overlap with the long formula I have in the middle.
Current code
I am using the bend right
option:
\begin{equation*}
\begin{tikzcd}
A
&
\\
BBBBBBBBB \ar{u}
&
\\
C \ar{u}\ar[uu,"f^*",bend right=90,swap]
&
\end{tikzcd}
\end{equation*}
Attempted solution
I attempted to use a control:
\begin{equation*}
\begin{tikzcd}
A
&
\\
BBBBBBBBB \ar{u}
&
\\
C \ar{u}\ar[uu,"f^*",to path={..controls +(2.5,1.5) .. (\tikztotarget)},swap]
&
\end{tikzcd}
\end{equation*}
This produces a diagram that looks like:
It's not overlapping anymore, but it doesn't look great, and more importantly the label $f^*$ disappeared.
