Goes and cheers up son after draw (8)
I believe the answer is:
attempts
'goes' is the definition.
'cheers up son after draw' is the wordplay.
'cheers up' becomes 'at' (I've seen this in other clues).
'son' becomes 's'.
'after' says to put letters next to each other.
'draw' becomes 'tempt' (I've seen this before).
's' put after 'tempt' is 'tempts'.
'at'+'tempts'='ATTEMPTS'
'and' is the link.
(Other definitions for attempts that I've seen before include "Endeavours, tries" , "Efforts, endeavours" , "Makes a stab at" , "Has a go at" , "Tries, makes an effort" .)
