Evaluate light for game (4,5)
I believe the answer is:
test match
'game' is the definition.
(type of cricket game)
'evaluate light' is the wordplay.
'evaluate' becomes 'test' (I've seen this in another clue).
'light' becomes 'match' (match is a kind of light).
'test'+'match'='TEST MATCH'
'for' is the link.
(Other definitions for test match that I've seen before include "Big game in India?" , "Lord's international?" , "International fixture" , "international - with 29a" , "Ashes tie, perhaps" .)
