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 explain this - if you can you should believe this answer much more).
'and' means one lot of letters go next to another.
'right' becomes 'r' (common abbreviation).
'winning' indicates putting letters inside (some letters win or obtain others).
'at last' indicates one should take the final letters.
The last letter of 'hole' is 'e'.
'porter' put 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" .)
