Wimbledon champion on comeback nets key point in game (4,6)
I believe the answer is:
real tennis
'game' is the definition.
(real tennis is a kind of game)
'wimbledon champion on comeback nets key point' is the wordplay.
I cannot really understand how this works, but
'on' could be 're' (regarding) and 're' is found in the answer.
'key' could be 'alt' (the Alt keyboard button) and 'alt' is found within the answer.
'point' could be 's' (South) and 's' is present in the answer.
This explanation may well be incorrect...
'in' is the link.
Can you help me to learn more?
(Other definitions for real tennis that I've seen before include "ancient game" , "In which court member served" , "Old sport" , "Game played in court" , "Early form of Wimbledon's game" .)
