Follow suit with thrust: that precedes victory in court (5,5)
I believe the answer is:
match point
'follow' is the definition.
Although both the answer and definition are singular nouns, I can't see how one could define the other.
'suit with thrust that precedes victory in court' is the wordplay.
I cannot really see how this works, but
'suit' could be 'match' (both can mean to go together) and 'match' is present in the answer.
'in' is found in the answer.
The remaining letters 'pot' is a valid word which might be clued in a way I don't understand.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for match point that I've seen before include "Decisive moment in game" , "could lead to victory in court" , "may secure victory in court" , "a single ace away from victory" , "that may bring victory" .)
