Goal in question dividing speculation (6)
I believe the answer is:
basket
'goal' is the definition.
(basket is a kind of goal)
'question dividing speculation' is the wordplay.
'question' becomes 'ask'.
'dividing' is an insertion indicator.
'speculation' becomes 'bet' (bet is a kind of speculation).
'ask' inserted into 'bet' is 'BASKET'.
'in' acts as a link.
(Other definitions for basket that I've seen before include "Container with handles" , "Container of woven twigs etc" , "Wicker carrier" , "Woven receptacle" , "Shopper may have this" .)
