In game of cards Jack drops, followed by Queen, to give easy decision (2-7)
I believe the answer is:
no-brainer
'easy decision' is the definition.
(I've seen this in another clue)
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for no-brainer that I've seen before include "That which must be done, obviously" , "Something requiring little thought" , "Something involving little or no mental effort" , "Obvious choice" , "Something requiring no mental thought" .)
