Legitimate target in coconut shy, possibly? (4,4)
I believe the answer is:
fair game
I believe this clue is a double definition.
'legitimate target' is the first definition.
(I've seen this before)
'coconut shy possibly?' is the second definition.
(game played at a fair)
'in' is the link.
(Other definitions for fair game that I've seen before include "hoopla, perhaps?" , "Aunt Sally, for example" , "coconut shy?" , "Legitimate object for attack or ridicule" , "Legitimate target in equitable contest" .)
