Smart trick (5)

Ross

I believe the answer is:

sting

I believe this is a double definition.

'smart' is the first definition.
(both can mean to burn or hurt)

'trick' is the second definition.
(sting can mean a cheat or trick)

(Other definitions for sting that I've seen before include "Con: leader singer of Police" , "Entrapment operation; sharp pain" , "The pain caused by bee or nettle" , "Wound from wasp" , "Sharp tingling pain" .)

I've seen this clue in The Times.
