Consider the minimal working example (from here):

\documentclass{book}
\usepackage{filecontents}
\begin{filecontents}{chapterref.dbx}
\DeclareDatamodelFields[type=field,datatype=literal]{
  shortdesc,
}
\DeclareDatamodelEntryfields{shortdesc}
\end{filecontents}

\usepackage[backref, refsegment=chapter, datamodel=chapterref, 
style=trad-alpha, % https://tex.stackexchange.com/a/69706/38244
minalphanames=3,maxalphanames=3 %https://github.com/moewew/biblatex-trad/issues/22
]{biblatex}
\usepackage[colorlinks]{hyperref}


\begin{filecontents}{\jobname.bib}
@misc{A01,
  author    = {Author, A. and Duthor, D.},
  year      = {2001},
  title     = {Alpha},
  shortdesc = {Conference1},
}


@misc{N02,
    author = {Nuthor, C.},
    title = {New title},
    year = {2001},
}


@misc{N03,
    author = {Nuthor, C},
    title = {More new title},
    year = {2000},
}


@misc{badum,
    author = {ba  Du  Tssh},
    title = {No new title},
    year = {2010},
}


\end{filecontents}


\addbibresource{\jobname.bib}


\begin{document}
  \chapter{First Chapter}
  Some more text \cite{A01}. More citation \cite{N02} and again \cite{N03}


Here is Ba-dum-tssh \cite{badum}.




\printbibliography
\end{document}

The problem I could not solve can be seen from the image:

Basically, there is an extra space between the author name's 3 characters and the year (possibly as the author name contains two spaces?). I want to get rid of the extra space, like this [bDu10].

    It's based on regular expressions, e.g., adding \s{} to the default nolabel definition (biblatex manual p 219) \DeclareNolabel{ % strip punctuation, symbols, separator and control characters \nolabel{\regexp{[\p{P}\p{S}\p{C}\s{}]+}} gives [DuT10]. – Cicada Sep 14 '20 at 11:27
