Crossword Genius

Awkward person playing charades (4,4)

Ross

I believe the answer is:

'awkward person' is the definition.
(term for a stubborn or tough person)

'playing charades' is the wordplay.
'playing' is an anagram indicator.
'charades' with letters rearranged gives 'HARD CASE'.

(Other definitions for hard case that I've seen before include "Intractable person", "challenge to legal team?", "Tough guy", "Brief problem, perhaps", "Tough person to deal with".)

I've seen this clue in The Guardian.
