Approaches snooker table but loses form? (4,2,3)
I believe the answer is:
goes to pot
'loses form?' is the definition.
(both can mean to decline in success or quality)
I cannot understand how the remainder of the clue works.
(Other definitions for goes to pot that I've seen before include "cracks up" , "Approaches the snooker table" , "Become ruined" , "Becomes bad" , "Prepares to follow snooker player" .)
