Dodging Nakamura's opening, Carlsen is a wise man (5)
I believe the answer is:
magus
'wise man' is the definition.
(I've seen this in another clue)
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for magus that I've seen before include "astrologer" , "eg Melchior" , "Sorcerer" , "Priest" , "Magician, wise man" .)
