Where good drivers may be handicapped (4,6)
I believe the answer is:
golf course
'where good drivers' is the definition.
Although both the answer and definition are singular nouns, I don't see how one could define the other.
'be handicapped' is the wordplay.
I cannot quite understand how this works, but
'be' could be 'go' (going is a kind of being) and 'go' is found within the answer.
This may be the basis of the clue (or it may be nonsense).
'may' acts as a link.
Can you help me to learn more?
(Other definitions for golf course that I've seen before include "Possibly links" , "area for drivers" , "Royal Troon or Carnoustie, for example" .)
