Photo - card game (4)
I believe the answer is:
snap
This clue is a double definition.
'photo' is the first definition.
(I know that snap is a type of photo)
'card game' is the second definition.
(simple card game)
(Other definitions for snap that I've seen before include "Photograph - card game" , "Be irritable at the card game" , "game of cards" , "Crack - shot" , "Crack; bite" .)
