It's played centre stage (3)
I believe the answer is:
tag
'it's' is the definition.
(playground catching game)
'centre stage' is the wordplay.
'centre' says to take the centre.
The middle letters of 'stage' are 'TAG'.
'played' acts as a link.
This may not be right. It may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for tag that I've seen before include "Identity disc" , "day in Berlin" , "dog" , "Identity badge" , "Children's chasing game" .)
