Officer deceives board (9)
I believe the answer is:
constable
'officer' is the definition.
(a police officer)
'deceives board' is the wordplay.
'deceives' becomes 'cons' (I've seen this in another clue).
'board' becomes 'table' (both can mean food).
'cons'+'table'='CONSTABLE'
(Other definitions for constable that I've seen before include "Flatford Mill painter" , "Copper - artist" , "In England, a great painter or lowly policeman" , "English landscape painter for a policeman" , "Policeman - landscape artist" .)
