Chicago, perhaps, takes charge of game (7,6)
I believe the answer is:
musical chairs
'game' is the definition.
(musical chairs is a kind of game)
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for musical chairs that I've seen before include "Game one can't stand to win" , "Traditional party game" , "Party game where children stand to lose!" , "Party activity" , "at the end, there's no score" .)
