Faced with a specialist (3)
I believe the answer is:
ace
'a specialist' is the definition.
The answer and definition can be both people as well as being singular nouns.
Maybe there's a link between them I don't understand?
'faced with' is the wordplay.
'with' indicates a hidden word.
'ACE' is hidden within 'faced'.
Can you help me to learn more?
(Other definitions for ace that I've seen before include "single > club > champion" , "One or 11 in cards" , "Tennis serve that the opponent can't reach" , "Playing card with a single symbol" , "strained" .)
