Hack about, left and right, winning hole at last (8)
I believe the answer is:
reporter
'hack' is the definition.
(informal term for a journalist)
'left and right winning hole at last' is the wordplay.
'left' becomes 'porter' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'and' says to put letters next to each other.
'right' becomes 'r' (abbreviation).
'winning' is an insertion indicator (some letters win or obtain others).
'at last' says to take the final letters.
The last letter of 'hole' is 'e'.
'porter' after 'r' is 'rporter'.
'rporter' going around 'e' is 'REPORTER'.
'about' is the link.
Can you help me to learn more?
(Other definitions for reporter that I've seen before include "He gives details" , "Newsman" , "One may write a column" , "Journo" , "Hack" .)
