Dodge Oscar in Strand (4)
I believe the answer is:
ploy
'dodge' is the definition.
(thesaurus)
'oscar in strand' is the wordplay.
'oscar' becomes 'o' (phonetic alphabet: alpha, bravo, charlie etc.).
'in' is an insertion indicator.
'strand' becomes 'ply' (ply is a kind of strand).
'o' going inside 'ply' is 'PLOY'.
(Other definitions for ploy that I've seen before include "'Stratagem, gambit (4)'" , "Ruse, stratagem" , "Cunning tactic" , "Cunning plan" , "Game manoeuvre" .)
