Finest — and worst? (4)
I believe the answer is:
best
I believe this clue is a double definition.
'finest' is the first definition.
('best' can be similar in meaning to 'finest')
'worst?' is the second definition.
(both can mean to beat someone)
'and' acts as a link.
(Other definitions for best that I've seen before include "Optimal" , "Most outstanding" , "Peerless" , "Cream of the crop" , "at 16 down [MAN UNITED] ?" .)
