Deceives, swindles (6)
I believe the answer is:
cheats
This clue is a double definition.
'deceives' is the first definition.
(cheating is a kind of deceiving)
'swindles' is the second definition.
(I know this)
(Other definitions for cheats that I've seen before include "Deceivers" , "Doesn't play fair" , "Chaste sort of swindlers" , "Doesn't follow the rules of the game" , "Dishonest dealers" .)
