Many thanks for your reply, Hans.

Hyphenation is the same in both documents.

Page break is wrong when any of the three values (brokenpenalty,
widowpenalty or clubpenalty) is 0 or above 9999.

I replacing \subsection with \section gives the right page break:

    \showframe\showgrid
    \setuplayout[setups=*lessstrict]
    \startsetups[*lessstrict]
        \setup[reset]
        \widowpenalty=10000
        \clubpenalty=10000
        \brokenpenalty=0
    \stopsetups
    \setupbodyfont[pagella, 12.6pt]
    \starttext
    \chapter{Quotes}
    \section{Zapf}
    \dorecurse{4}{\input zapf\par}
    \section{Knuth}
    \input knuth
    \stoptext

Why does \subsection cause a different page break than \section?

Many thanks for your help,


Pablo
