Skilful, shrewd (5)
I believe the answer is:
canny
I believe this clue is a double definition.
'skilful' is the first definition.
'shrewd' is the second definition.
(both can mean having good judgement)
(Other definitions for canny that I've seen before include "Astute" , "Shrewd, clever" , "Fly" , "Shrewd like Scotsman" , "Shrewd, knowing" .)
