How to check light is satisfactory for cricket game?
I believe the answer is:
test match
'light is satisfactory for cricket game?' is the definition.
I can't tell whether this defines the answer.
'how to check' is the wordplay.
'how' becomes 'match' (I can't justify this - if you can you should believe this answer much more).
'to' is a charade indicator (letters next to each other) (I've seen this in other clues).
'check' becomes 'test' ('test' can be a synonym of 'check').
'match' after 'test' is 'TEST MATCH'.
Can you help me to learn more?
(Other definitions for test match that I've seen before include "Lord's international?" , "International fixture" , "Strike a light!" , "International sports event" , "Cricket contest between countries, usually one of a series" .)
