Beat at golf, maybe? (4)
I believe the answer is:
flog
'beat' is the definition.
(I know that flog is a more specific form of beat)
'golf maybe?' is the wordplay.
'maybe?' indicates an anagram (I've seen 'maybe' mean this).
'golf' anagrammed gives 'FLOG'.
'at' acts as a link.
(Other definitions for flog that I've seen before include "Hit - sell" , "Beat with a whip or rod" , "-- Hitler" , "Whip severely" , "Keep hitting" .)
