Try to win women’s love on more than one occasion (3)
I believe the answer is:
woo
'try to win' is the definition.
'women's love on more than one occasion' is the wordplay.
'women' becomes 'w'.
'love' becomes 'o' (In tennis, 'love' means 'zero').
'on more than one occasion' indicates the doubling of some letters.
'o' duplicated is 'oo'.
'w'+'oo'='WOO'
(Other definitions for woo that I've seen before include "Court, romance" , "Try to get the girl?" , "Court a lady" , "Do courting" , "Try to attract" .)
