Central Europe takes satisfactory man on board (4)
I believe the answer is:
rook
'man on board' is the definition.
(man can mean a chess piece)
'central europe takes satisfactory' is the wordplay.
'central' means to look at the middle letters.
'takes' is a charade indicator (letters next to each other).
'satisfactory' becomes 'ok' (similar in meaning).
The central letters of 'europe' are 'ro'.
'ro'+'ok'='ROOK'
(Other definitions for rook that I've seen before include "embattled man" , "journalist Jean" , "Castle -- bird" , "Defraud; bird; chessman" , "Chesspiece otherwise known as a castle" .)
