Faced with expert (3)
I believe the answer is:
ace
'expert' is the definition.
(ace can informally mean very good)
'faced with' is the wordplay.
'with' indicates the answer is hidden within the clue.
'ACE' is hidden within 'faced'.
(Other definitions for ace that I've seen before include "Brilliant" , "'wicked'!" , "Crack" , "Top card or winning tennis serve" , "Possibly a diamond" .)
