Play golf? I’ll be hanged if I will! (5)
I believe the answer is:
swing
'play' is the definition.
(swing is a kind of play)
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for swing that I've seen before include "be hanged?" , "Brandish" , "Move from side to side" , "Big band jazz" , "style of music" .)
