Worked out fast, avoiding first chance after some thought? (10,4)

Ross

I believe the answer is:

calculated risk

'chance after some thought?' is the definition.
(a risk or chance that has been thought about)

'worked out fast avoiding first' is the wordplay.
'worked out' becomes 'calculated' (I've seen this before).
'fast' becomes 'brisk' (I've seen this in another clue).
'avoiding first' means to remove the first letter.
'brisk' with its initial letter removed is 'risk'.
'calculated'+'risk'='CALCULATED RISK'

I've seen this clue in The Times.
