Expert (4,6)

Ross

'expert' is the definition.
(ace can informally mean very good)

This is the entire clue.

(Other definitions for ace that I've seen before include "Very good; playing card" , "reason for point of no return" , "One; A1" , "Top card or winning tennis serve" , "Crack" .)

I've seen this clue in the Penny Press, The Sun, the King Feature Syndicate, The New York Times, The Telegraph, The Wall Street Journal, The Star Tribune, the Evening Standard, the LA Times, The Times, the Universal, The Mirror and the USA Today.
