Prepare to shoot for goal (3)
I believe the answer is:
aim
I believe this is a double definition.
'prepare to shoot' is the first definition.
(as in aiming a gun)
'goal' is the second definition.
(aim is a kind of goal)
'for' is the link.
(Other definitions for aim that I've seen before include "Point towards a target, or have ambition" , "Purpose, intention" , "intent" , "Goal, objective" , "Attempt" .)
