Acceptable target in 'Test Your Strength' or 'Hook a Duck'? (4,4)
I believe the answer is:
fair game
'acceptable target' is the definition.
(I've seen this before)
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for fair game that I've seen before include "Hoop-la may be" , "Legitimate objects for attack" , "Suitable target" , "Fear magi with legitimate target" , "Legitimate target like blonde animal" .)
