Photograph; card game (4)
I believe the answer is:
snap
I believe this is a double definition.
'photograph' is the first definition.
(I know that snap is a type of photograph)
'card game' is the second definition.
(simple card game)
(Other definitions for snap that I've seen before include "Collapse" , "Break suddenly with cracking sound" , "Break sharply - a simple card game" , "game of cards" , "Become unhinged" .)
