About to yield and draw back (6)
I believe the answer is:
recede
'draw back' is the definition.
(I know that draw back can be written as recede)
'about to yield' is the wordplay.
'about' becomes 're' ('re' means regarding or about).
'to yield' becomes 'cede' ('cede' can be a synonym of 'yield').
're'+'cede'='RECEDE'
'and' is the link.
(Other definitions for recede that I've seen before include "Withdraw" , "Move backward" , "Become more distant" , "Decline" , "Go back, ebb" .)
