Most of the cheats making pounds (6)
I believe the answer is:
throbs
'pounds' is the definition.
(throbbing is a kind of pounding)
'most of the cheats' is the wordplay.
'most of' means to remove the last letter.
'cheats' becomes 'robs' (robbing is a kind of cheating).
'the' with its final letter taken off is 'th'.
'th'+'robs'='THROBS'
'making' is the link.
(Other definitions for throbs that I've seen before include "Pulsates like heart" , "Pulsates, with pain perhaps" , "Beats like the heart" , "Pounds" , "Beats with persistent rhythm, as heart does" .)
