Deceived by a cunning old foe (6)

Ross

I believe the answer is:

fooled

'deceived' is the definition.
(fooling is a kind of deceiving)

'a cunning old foe' is the wordplay.
'a cunning' is an anagram indicator.
'old'+'foe'='oldfoe'
'oldfoe' is an anagram of 'FOOLED'.

'by' acts as a link.

I've seen this clue in the Evening Standard.
