Ship’s officer with another moving victory (6,4)
I believe the answer is:
second mate
'ship's officer' is the definition.
(another term for the second officer of a ship)
'with another moving victory' is the wordplay.
'with' is a charade indicator (letters next to each other).
'another' becomes 'second'.
'moving victory' becomes 'mate' (victory with chess moves).
'second' put next to 'mate' is 'SECOND MATE'.
(Other definitions for second mate that I've seen before include "Craftsman, perhaps" , "Naval officer" , "one involved in bigamy?" .)
