Soren Hansen is only the 2nd player from Denmark to play for the European side, while making his debut at the 2008 Ryder Cup. He has a nice simple swing, with some great fundamentals, which are illustrated very well in the video above.
The first thing to watch is his backswing. He makes a nice smooth motion during his takeaway, but it his position at the top that is so solid. The key to this position is how short his arm swing is. Notice how his hands fall short of his shoulders. Yet his club is still parallel to the ground. This is a great position. He can create a lot of power from here, and also keep his swing easy to repeat.
In order to create this position you must make a body turn backswing. Turn your chest away from your target. When you stop turning your chest you should also stop your arms from moving. This keeps them together. It is important to know that it is your turn, and the proper hinging of your wrists that will get your club to the top of your backswing, and not your arms.
The second thing to watch for is his head during his downswing. If you look closely you can see how the right edge of his hat is in line with the instep of his right foot when he gets to the top of his backswing. Watch how as he swings down to hit the ball his head and hat stay in the same position until well after impact. The key learning here is not that his head stayed ‘down’ but that it did not slide towards his target. If your head starts sliding towards your target as you make your downswing then you are going to come into your ball too steep and hit a lot of shots high right. Keep your head back for longer and straighter shots.
