Captured also with king (4)
I believe the answer is:
took
'captured' is the definition.
(take can mean to capture or get control of)
'also with king' is the wordplay.
'also' becomes 'too' (synonyms).
'with' is a charade indicator (letters next to each other).
'king' becomes 'K' (abbreviation for king in chess).
'too'+'k'='TOOK'
(Other definitions for took that I've seen before include "Purloined" , "Small stem of flowers" , "Seized" , "Captured" , "removed from chessboard" .)
