Cheat to provoke scorn (8)
I believe the answer is:
contempt
'scorn' is the definition.
(I know that scorn can be written as contempt)
'cheat to provoke' is the wordplay.
'cheat' becomes 'con' (con is a kind of cheat).
'to provoke' becomes 'tempt' (tempting is a kind of provoking).
'con'+'tempt'='CONTEMPT'
(Other definitions for contempt that I've seen before include "Disregard for the rules of a court of law" , "Disobedience to the rule of court of law" , "The feeling of despising someone" , "ridicule" , "Disobedience to the rules of a court of law" .)
