Sneaky maneuver (4)
I believe the answer is:
ploy
'sneaky maneuver' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for ploy that I've seen before include "Clever tactic" , "Ruse, stratagem" , "Game manoeuvre" , "Tactical scheme" , "Cunning manoeuvre to gain advantage" .)
