If you have a bad takeaway, you will hit a bad shot. Most problems in the golf swing, if your set up is right, can be traced back to the takeaway. If you get your set up and takeaway right, your swing will take care of itself and you will have a great looking golf swing.
A lot of professional players will spend all of their practice time grooving their takeaway. Golfers such as New Zealand player Michael Campbell does a couple of takeaway rehearsals when he standing over the ball before beginning his swing. He does this to ingrain the right move in his muscle memory.
If you take the club away closed, you club will "shut" at the top of the backswing. On the other hand, if you open the clubface too much on the backswing, your club will be open at the top and you will likely hit a lot of slices.
First, let's get our definitions right - "take" suggests using the hands and wrists to start the backswing. What you want to do, rather, is move the club away with your shoulders and your torso rather than the hands and wrists. You want the left arm to rotate slightly in and the right forearm to rotate slightly out. The butt end of the club won't have moved a long way but the club head will have moved more.
Make an effort to start your swing slowly. The club should gather speed gradually and many bad backswings start with the golfer "snatching" the club away from the ball.
Considering all aspects of a golf course you’ve never played before takes a bit of time. But you will reap the rewards of that effort during play. Your final score will surprise your opponents who thought they had one up on you because of their familiarity with the course. So take the time and do your homework. Making a habit of doing so will improve your game immensely. Golf is, after all, as much about strategy as it is about skill.
