Fixes problem revealed by clubs (5,3)
I believe the answer is:
irons out
'fixes problem' is the definition.
The answer and definition can be both to do with contact as well as being verbs in their -s form.
Perhaps there's a link between them I don't understand?
'revealed by clubs' is the wordplay.
'revealed' becomes 'out' (as in news which is out).
'by' says to put letters next to each other.
'clubs' becomes 'irons' (iron is a kind of club).
'out' put after 'irons' is 'IRONS OUT'.
Can you help me to learn more?
(Another definition for irons out that I've seen is " Settles".)
