Great tennis playing to capture the point (7)
I believe the answer is:
intense
'great' is the definition.
(I've seen this before)
'tennis playing to capture the point' is the wordplay.
'playing' indicates an anagram.
'to capture' indicates putting letters inside.
'the point' becomes 'E' (compass point).
'tennis' with letters rearranged gives 'intnse'.
'intnse' enclosing 'e' is 'INTENSE'.
(Other definitions for intense that I've seen before include "Deeply emotional" , "Acute difficulty" , "Strong in degree or emotion" , "Concentrated, serious" , "Strongly felt" .)
