Cut in a card game (7)
I believe the answer is:
abridge
'cut' is the definition.
('abridge' can be a synonym of 'cut')
'a card game' is the wordplay.
'card game' becomes 'bridge' (bridge is a kind of card game).
'a'+'bridge'='ABRIDGE'
'in' acts as a link.
(Other definitions for abridge that I've seen before include "Crop" , "Reduce the length of" , "Cut short" , "Abbreviate, shorten" , "Condense, summarise" .)
