Card cheat of old (5)

I believe the answer is:

knave

This clue is a double definition.

'card' is the first definition.
(I know that knave is a type of face card)

'cheat of old' is the second definition.
(I've seen this before)

(Other definitions for knave that I've seen before include "A swindler" , "Villain - jack" , "Jack - rotter" , "Jack (card); base fellow" , "Yet he may be a diamond" .)

I've seen this clue in The Sun.
