Repeat dance for man on board (6)
I believe the answer is:
bishop
'man on board' is the definition.
(chess)
'repeat dance' is the wordplay.
'repeat' becomes 'bis' (musical direction meaning 'play again').
'dance' becomes 'hop' (hop is a kind of dance).
'bis'+'hop'='BISHOP'
'for' acts as a link.
(Other definitions for bishop that I've seen before include "Chess piece and one of the clergy" , "Senior church minister" , "Church dignitary" , "Church leader" , "Senior cleric" .)
