One of the most common problems that people who tend to push their shots to the right is that when they set up they are tilted too much to the right. The right side is too low, the left side is tilted back so as they swing the path of their swing tends to go too much to the right. So what you want to try to do is raise your right shoulder so that as you set up your spine is more or less up and down. A good drill to help you do that is what I call the Tripod Drill. You should set up so that both of your legs are at the same angle coming down from your torso; you should not have one straight up and down and the other angled back. Then take the club right out in front of your body, parallel to the ground, and without leaning one way or the other just bend over until the club touches the ground. Flex your knees so that you have what would look the appearance of a tripod. So remember, both legs at the same angle, club in front, tilt over like a tripod and there is your set up to eliminate that in to out path which produces that push shot.
