Pursue this writer's chief in game (6-2-6)
I believe the answer is:
follow-my-leader
'game' is the definition.
(I've seen this before)
'pursue this writer's chief' is the wordplay.
I cannot quite see how this works, but
'pursue' could be 'follow' (I've seen this before) and 'follow' is present in the answer.
'writer's' could be 'my' (belonging to the person who set the crossword) and 'my' is found within the answer.
'chief' could be 'leader' (I've seen this in another clue) and 'leader' is found within the answer.
This accounts for all the letters.
This explanation may well be incorrect...
'in' is the link.
Can you help me to learn more?
(Another definition for follow-my-leader that I've seen is " Mimicking game".)
