Cheat and win in a doctored sled (7)
I believe the answer is:
swindle
'cheat' is the definition.
(synonyms)
'win in a doctored sled' is the wordplay.
'in' indicates putting letters inside.
'a doctored' indicates anagramming the letters.
'sled' with letters rearranged gives 'sdle'.
'win' going inside 'sdle' is 'SWINDLE'.
'and' is the link.
(Other definitions for swindle that I've seen before include "Fraudulent scheme" , "Trick" , "Ramp" , "Rip off" , "Cheat (out of money)" .)
