Admit to dishonest scheme and surrender (7)
I believe the answer is:
concede
'admit' is the definition.
(conceding is a kind of admiting)
'dishonest scheme and surrender' is the wordplay.
'dishonest scheme' becomes 'con' (I can't justify this - if you can you should give a lot more credence to this answer).
'and' is a charade indicator (letters next to each other).
'surrender' becomes 'cede' (synonyms).
'con'+'cede'='CONCEDE'
'to' is the link.
Can you help me to learn more?
(Other definitions for concede that I've seen before include "Allow - give up" , "Make admission" , "Make concession" , "Admit something is true" , "Admit; surrender" .)
