Good player after women times header in effortless turn (9)
I believe the answer is:
pirouette
'turn' is the definition.
(I know that pirouette is a type of pivot)
'good player after women times header in effortless' is the wordplay.
'good' becomes 'pi' (old-fashioned term for pious).
'player after women' becomes 'roue' (old-fashioned term for a womaniser).
'header' indicates taking the first letters (in a down clue, the letter at the top of the word).
'in effortless' becomes 'te' (I can't explain this - if you can you should believe this answer much more).
The initial letter of 'times' is 't'.
'pi'+'roue'+'t'+'te'='PIROUETTE'
(Other definitions for pirouette that I've seen before include "Balletic whirl" , "Rapid spin of the body on the toes in ballet" , "Twirl like a ballerina" , "Dancer's twirl" , "Spin on one foot" .)
