Like an alarm to fail in shabby dive? (5,4)
I believe the answer is:
belly flop
'shabby dive?' is the definition.
'belly flop' can be an answer for 'dive?' (I have seen 'Unfortunate dive' mean 'belly flop' so perhaps 'dive' could also mean 'belly flop'). I'm unsure of the 'shabby' bit.
'like an alarm to fail' is the wordplay.
'like an alarm' becomes 'belly' (I can't justify this - if you can you should believe this answer much more).
'to fail' becomes 'flop' (flopping is a kind of failing).
'belly'+'flop'='BELLY-FLOP'
'in' is the link.
Can you help me to learn more?
(Other definitions for belly flop that I've seen before include "Clumsy dive" , "unattractive dive" , "Awkward dive" , "Ungainly sprawling dive" , "Unfortunate dive" .)
