It's played with much love (4)
I believe the answer is:
faro
'it's played' is the definition.
I can't judge whether this definition defines the answer.
'with much love' is the wordplay.
'with' says to put letters next to each other.
'much' becomes 'far' (I've seen this in other clues).
'love' becomes 'o' (love means zero in tennis).
'far'+'o' is 'FARO'.
Can you help me to learn more?
(Other definitions for faro that I've seen before include "Portuguese seaport" , "Algarve seaport" , "Card game - Algarve port" , "Portuguese city" , "Portuguese, 22 [RESORT]" .)
