In the best position possibly not to go to work (2,3)
I believe the answer is:
on top
'in the best position' is the definition.
I don't know anything about this answer so I cannot judge whether this works.
'not to go to work' is the wordplay.
I cannot really see how this works, but
an anagram of 'not' is 'ont' which is within the answer.
'work' could be 'op' (common abbreviation for 'opus') and 'op' is found within the answer.
No letters remain.
This may be the basis of the clue (or it may be nonsense).
'possibly' is the link.
Can you help me to learn more?
(Other definitions for on top that I've seen before include "Leading" , "Winning" , "In a dominant position" , "At the summit or in superior position" .)
