To cheat can involve bowing and scraping! (6)
I believe the answer is:
fiddle
'to cheat' is the definition.
(I've seen this before)
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for fiddle that I've seen before include "Stringed instrument - cheat" , "Violin; falsify (figures)" , "Fraudulent instrument?" , "do crookedly with books" , "Toy - string instrument - cheat" .)
