Cheat at every turn? (5)
I believe the answer is:
twist
This clue might be a double definition.
'cheat' is the first definition.
(I've seen this before)
'every turn?' is the second definition.
'twist' can be an answer for 'turn?' ('twist' can be a synonym of 'turn'). I am not certain of the 'every' bit.
'at' acts as a link.
Can you help me to learn more?
(Other definitions for twist that I've seen before include "Spin - pervert" , "Misrepresent - dance" , "bread" , "Request for another card" , "Embellishment to plot" .)
