Winners of a case, perhaps (4)
I believe the answer is:
aces
'winners' is the definition.
The answer and definition can be both people as well as being plural nouns.
Maybe there's a link between them I don't understand?
'a case perhaps' is the wordplay.
'perhaps' indicates anagramming the letters.
'case' is an anagram of 'ACES'.
'of' is the link.
Can you help me to learn more?
(Other definitions for aces that I've seen before include "wartime pilots?" , "Playing cards with single pips on their faces" , "Unreturnable services" , "never come back" , "Two will make deuce" .)
