Bishop taken in and defeated (6)
I believe the answer is:
beaten
'defeated' is the definition.
(similar in meaning)
'bishop taken in' is the wordplay.
'bishop' becomes 'B' (abbreviation for bishop in chess).
'taken in' becomes 'eaten' (take in can mean to eat).
'b'+'eaten'='BEATEN'
'and' acts as a link.
(Other definitions for beaten that I've seen before include "Vanquished" , "Stuffed" , "Formed or made thin by hammering" , "Baffled" , "Worsted" .)
