Important match suspended, interrupted by fool turning and shooting wildly? (3,4,7)
I believe the answer is:
big game hunting
'shooting wildly?' is the definition.
(hunting and shooting wild animals)
'important match suspended interrupted by fool turning' is the wordplay.
'important match' becomes 'biggame' (I've seen this before).
'suspended' becomes 'hung' (I've seen this before).
'interrupted by' is an insertion indicator.
'fool' becomes 'nit' (I've seen this before).
'turning' says the letters should be written in reverse.
'nit' reversed gives 'tin'.
'hung' enclosing 'tin' is 'hunting'.
'biggame'+'hunting'='BIG GAME HUNTING'
'and' acts as a link.
(Another definition for big game hunting that I've seen is " risk to pride?".)
