Crossword Genius

Brilliant as one at cards? (3)

Ross

I believe the answer is:

ace

I believe this is a triple definition!

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

'as' acts as a link.

'one' is the second definition.
(ace has a value of one in some card games)

'at' acts as a link.

'cards?' is the third definition.
(thesaurus)

(Other definitions for ace that I've seen before include "Entertain" , "star" , "unit > of highest quality" , "Player who excels" , "Playing card with single spot" .)

I've seen this clue in The Sun.
