Fly out of bounds, doomed (2-3)
I believe the answer is:
no-win
'doomed' is the definition.
I know nothing about this answer so I cannot judge whether this works.
'fly out of bounds' is the wordplay.
'fly' becomes 'knowing' (I've seen this before).
'out of bounds' says to take the centre (the bounds or edges of the word are removed).
The central letters of 'knowing' are 'NO-WIN'.
Can you help me to learn more?
(Other definitions for no-win that I've seen before include "Denoting situation in which success is impossible" , "Certain to end in failure" .)
