I'm a little stuck... Click here to teach me more about this clue!

This clue could be a double definition.

'approach snooker shot' is the first definition.
I know that 'snooker' relates to this answer.

'fail completely' is the second definition.
'go to pot' can be an answer for 'fail' (thesaurus). I am unsure of the 'completely' bit.

'and' acts as a link.

Can you help me to learn more?

(Other definitions for go to pot that I've seen before include "as stakes do" , "If you want a cup of tea" , "Fall into ruin" , "Fall into neglect" , "Decline" .)
