While preparing to play the shot, solve the problem (4,3)
I believe the answer is:
iron out
I'm afraid I can't even guess how this answer relates to the clue.
Can you help me to learn more?
(Other definitions for iron out that I've seen before include "Get sorted" , "Solve (one's differences?)" , "Clear up (problems)" , "what golfer needs on tee" , "Settle (problems)" .)
