Hi Tuesday, Boomerang and Dutchy
I have the same cryptic answers as Dutchy:
14D. He directs from back seat during race = Jockey
25A. Codes = Cyphers (variant spelling of 'ciphers')
at first = the 'first letter of each word in the clue spells out the answer
Codes You Produced Had Everyone Really Stumped
Post again if you get stuck Tuesday and we'll do our best to help you.
Happy New Year to you all!
Regards, Butterfly
