# Don't show initials in short version of author with same last name in biblatex windy city style

Currently in the windycity style of biblatex, authors with the same last name will show initials when their short form is called. The Chicago Manual of Style, however, is unclear on whether this is needed when it can easily be determined which author is intended. I would like to remove this behaviour for my document. Ideally on a case by case basis, and otherwise for all entries. How can this best be done?

MWE:

\documentclass{article}
\usepackage[style=windycity]{biblatex}
\begin{filecontents}{biblio.bib}
@book{book1,
title = {First Book},
author = {Author, The},
location = {Place},
publisher = {Publisher},
date = {1980},
}
@book{book2,
title = {Second Book},
author = {Author, Another},
location = {Place},
publisher = {Publisher},
date = {2020},
}
\end{filecontents}
\bibliography{biblio}
\begin{document}
\cites{book1}{book2}

\cites{book1}{book2}
\end{document}


gives for the second citation:

T. Author, First Book; A. Author, Second Book.

but the second citation to produce:

Author, First Book; Author, Second Book.

This is caused by the uniquename feature, which tries to ensure unique label names. The feature can be turned off globally with the option uniquename=false,. See also biblatex, authoryear style: In-text citations display first name initials for certain bibliography entries.

With newer versions of biblatex, it is also possible to give the uniquename option on a per-entry basis, which may or may not be more convenient for you. Note that turning off uniquename for one entry may affect other entries as well, since a disambiguation is no longer required if a particular name entry is ignored by the feature.

\documentclass{article}
\usepackage[style=windycity]{biblatex}
\begin{filecontents}{\jobname.bib}
@book{book1,
title     = {First Book},
author    = {Author, The},
location  = {Place},
publisher = {Publisher},
date      = {1980},
}
@book{book2,
title     = {Second Book},
author    = {Author, Another},
location  = {Place},
publisher = {Publisher},
date      = {2020},
options   = {uniquename=false},
}
\end{filecontents}
