Concedes, at three points to nil (4)
I believe the answer is:
owns
'concedes' is the definition.
'three points to nil' is the wordplay.
'three points' becomes 'wns' ().
'to' is a charade indicator (letters next to each other) (I've seen this in other clues).
'nil' becomes 'O' (O resembles 0).
'wns' after 'o' is 'OWNS'.
'at' is the link.
(Other definitions for owns that I've seen before include "Has possession of by right" , "Belongs to" , "Confesses" , "Possesses" , "uses" .)
