No luck in unusually good opening (9)

Ross

I believe the answer is:

unlocking

'opening' is the definition.
(unlocking is a kind of opening)

'no luck in unusually good' is the wordplay.
'unusually' indicates anagramming the letters.
'good' becomes 'g' (abbreviation).
'no'+'luck'+'in'='noluckin'
'noluckin' with letters rearranged gives 'unlockin'.
'unlockin'+'g'='UNLOCKING'

(Another definition for unlocking that I've seen is " Releasing".)

I've seen this clue in The Telegraph.
