Select game for old opener (10)
I believe the answer is:
drawbridge
'old opener' is the definition.
The definition and answer can be both man-made objects as well as being singular nouns.
Perhaps they are linked in a way I don't understand?
'select game' is the wordplay.
'select' becomes 'draw' (I can't justify this - if you can you should give a lot more credence to this answer).
'game' becomes 'bridge' (card game).
'draw'+'bridge'='DRAWBRIDGE'
'for' acts as a link.
Can you help me to learn more?
(Other definitions for drawbridge that I've seen before include "Removable access to castle" , "Barbican may defend this" , "Castle defence" , "form of security" , "that's raised by defenders" .)
