The place in which that woman punches partners (5)
I believe the answer is:
where
'the place' is the definition.
(I've seen this in another clue)
'that woman punches partners' is the wordplay.
'that woman' becomes 'her' (her refers to a woman).
'punches' is an insertion indicator (some letters punch a hole in others).
'partners' becomes 'we' (West and East are partners in the game bridge).
'her' placed inside 'we' is 'WHERE'.
'in which' is the link.
(Other definitions for where that I've seen before include "enquiry" , "A question of place?" , "a question of location" , "At which point" , "In which position?" .)
