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 can't justify this - if you can you should give a lot more credence to this answer).
'and' is a charade indicator (letters next to each other).
'right' becomes 'r' (common abbreviation).
'winning' means one lot of letters goes inside another (some letters win or obtain others).
'at last' indicates one should take the final letters.
The last letter of 'hole' is 'e'.
'porter' after 'r' is 'rporter'.
'rporter' going around 'e' is 'REPORTER'.
'about' acts as a 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" .)
