Teacher poses for shot with Queen (9)
I believe the answer is:
professor
'teacher' is the definition.
(thesaurus)
'poses for shot with queen' is the wordplay.
'shot with' is an anagram indicator.
'queen' becomes 'r' (r is abbreviation regina. e.g. in ER ).
'poses'+'for'='posesfor'
'posesfor' anagrammed with 'r' gives 'PROFESSOR'.
(Other definitions for professor that I've seen before include "Fellow" , "High-ranking academic" , "One affirming faith" , "University lecturer" , "Senior university teacher" .)
