Game withdrawing place for quiz buff (3,2)
I believe the answer is:
rub up
'buff' is the definition.
(buff can mean to rub or polish)
'game withdrawing place for quiz' is the wordplay.
'game' becomes 'RU' (rugby union).
'withdrawing' shows that the letters should be reversed in order.
'place for quiz' becomes 'pub' (venue for a pub quiz).
'pub' written backwards gives 'bup'.
'ru'+'bup'='RUB UP'
(Other definitions for rub up that I've seen before include "shine" , "Polish" .)
