No knight, evidently, taking queen in game (5)
I believe the answer is:
roque
'no knight evidently' is the definition.
I can't judge whether this defines the answer.
'queen in game' is the wordplay.
'queen' becomes 'qu' (abbreviation for queen).
'in' means one lot of letters goes inside another.
'game' becomes 'roe' (I am not sure about this - if you are sure you should believe this answer much more).
'qu' inserted within 'roe' is 'ROQUE'.
'taking' acts as a link.
Can you help me to learn more?
(Another definition for roque that I've seen is " US court game".)
