Old defence area not fiddled with in high-scoring draw? (8,4)
I believe the answer is:
antonine wall
'area not fiddled with in high-scoring draw?' is the definition.
I don't know anything about this answer so I cannot judge whether it can be defined by this definition.
'old defence' is the wordplay.
'old' becomes 'antonine' (I can't explain this - if you can you should believe this answer much more).
'defence' becomes 'wall' (wall is a kind of defence).
'antonine'+'wall'='ANTONINE WALL'
Can you help me to learn more?
(Other definitions for antonine wall that I've seen before include "defence system" , "Roman fortification between the Forth and Clyde" .)
