Nearly trick chess champion, making exchanges (7)
I believe the answer is:
trading
'champion making exchanges' is the definition.
Although both the answer and definition are singular nouns, I can't understand how they can define each other.
'nearly trick chess' is the wordplay.
'nearly' means to remove the last letter.
'trick' becomes 'trap' (I've seen this in another clue).
'chess' becomes 'ding' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'trap' with its last letter taken away is 'tra'.
'tra'+'ding'='TRADING'
Can you help me to learn more?
(Other definitions for trading that I've seen before include "Buying and selling" , "Exchanging; a word used in the first ever 2 dn" , "In business" , "Commercial activity" , "in the marketplace" .)
