Coy about games played in plantation (9)
I believe the answer is:
shrubbery
'plantation' is the definition.
(where shrubs are grown)
'coy about games played' is the wordplay.
'coy' becomes 'shy' (I've seen this before).
'about' means one lot of letters goes inside another.
'games played' becomes 'rubber' (rubber can mean a group of matches).
'shy' placed around 'rubber' is 'SHRUBBERY'.
'in' acts as a link.
(Other definitions for shrubbery that I've seen before include "Garden site of small woody plants" , "collection of plants" , "Bushy part of garden" , "Bushy garden area" , "Rosemary's place" .)
