King that's opposed to the city (4)
I believe the answer is:
kiev
'the city' is the definition.
(Kiev is an example)
'king that's opposed' is the wordplay.
'king' becomes 'K' (abbreviation for king in chess).
'that's' becomes 'ie'.
'opposed' becomes 'v' (abbreviation for versus).
'k'+'ie'+'v'='KIEV'
'to' acts as a link.
(Other definitions for kiev that I've seen before include "place in eastern Europe" , "FC Dynamo/chicken ___" , "Capital city of the Ukraine" , "Ukraine's largest city" , "Ukraine's capital - way of cooking chicken" .)
