Knowing there will be a fight to gain the point (5)
I believe the answer is:
aware
'knowing' is the definition.
(I've seen this before)
'a fight to gain the point' is the wordplay.
'fight' becomes 'war' (warring is a kind of fighting).
'to gain' is a charade indicator (letters next to each other).
'the point' becomes 'E' (E is an example).
'a'+'war'+'e'='AWARE'
'there will be' is the link.
(Other definitions for aware that I've seen before include "Cognizant" , "fly" , "Conscious or having knowledge of" , "Alert, conscious of" , "Attentive" .)
