Energy needed by snooker player possibly in decline (2,2,3)
I believe the answer is:
go to pot
This clue might be a double definition.
'energy needed by snooker player possibly' is the first definition.
I know that 'snooker' relates to this answer.
'decline' is the second definition.
(I've seen this before)
'in' is the link.
Can you help me to learn more?
(Other definitions for go to pot that I've seen before include "Fall into neglect" , "Approach snooker table" , "If you want a cup of tea" , "Fall into ruin" , "Decline" .)
