# openright option for \part and not for \chapter

I need in a book class document to open the \part in an odd page. The option \documentclass[twoside, openright]{book} is very convenient.

Unfortunately, I want to keep my \chapter opening on any pages.

Here a MWE:

\documentclass[twoside, openright]{book}
\begin{document}
\part{1st part begin in an odd page, perfect}
\chapter{chapter begin in an odd page and not on anypage}
\end{document}


How can I fix that? Declaring

\makeatletter\@openrightfalse
\chapter{Chapter begin in any page}
\@openrighttrue\makeatother


for each chapter is not a good solution for me... Same for the reverse method if I should redefine openright on each part.

Sorry for my english.

simplest, assuming you don't have many parts is to use openany and start each part with

\cleardoublepage
\part


if you do not want the \cleardoublepage to be explicit then just use \part and put

\let\oldpart\part
\def\part{\cleardoublepage\oldpart}


in the preamble of your document

• The first solution is not exactly what i was looking for. The second one works perfectly and fits exactly with what i wanted ! Thanks a lot ! – Piroooh Sep 29 '18 at 15:08
