Be impartial and note this crooked receiver (3,2,3,5)
I believe the answer is:
sit on the fence
'be impartial' is the definition.
I don't know anything about this answer so I can't tell whether this works.
'note this crooked receiver' is the wordplay.
'crooked' is an anagram indicator.
'receiver' becomes 'fence' (I've seen this before).
'note'+'this'='notethis'
'notethis' is an anagram of 'sitonthe'.
'sitonthe'+'fence'='SIT ON THE FENCE'
'and' is the link.
Can you help me to learn more?
(Other definitions for sit on the fence that I've seen before include "Remain undecided" , "Don't commit oneself" , "Decline to commit oneself" , "Prevaricate" , "pin down criminal" .)
