Score on the off side? Get away! (3,3,3)
I believe the answer is:
cut and run
'score on' is the definition.
I don't know anything about this answer so I cannot tell whether this works.
'off side? get away' is the wordplay.
I cannot really see how this works, but
'side?' could be 'cut' (side is a kind of cut) and 'cut' is present in the answer.
'get' could be 'run' (running is a kind of getting) and 'run' is found in the answer.
'away' could be 'a' (abbreviation as used in sports fixtures) and 'a' is located in the answer.
This may be the basis of the clue (or it may be nonsense).
'the' is the link.
Can you help me to learn more?
(Other definitions for cut and run that I've seen before include "Make a rapid escape" , "How to deal with short ball" , "Exit a thorny situation rather than deal with it" , "A batsman may" , "Escape quickly from a difficult situation" .)
