Most rounds of golf will produce abnormal lies. Handling these situations is not that difficult if you approach your shot with a positive mental attitude and adjust your swing accordingly.
Uphill lie. Take a normal stance, standing perpendicular to the slope. Take the club back parallel to the slope and swing easily. Balls hit from uphill lies tend to hook. Aim right to compensate.
Downhill lies. This is the most difficult lie to hit from. Stand perpendicular to the slope and play the ball back in your stance. Follow the slope on the backswing and stay down through the impact zone. Dont lift your head!
Ball above the feet. Choke down on the club. Play for a hook. Ball below the feet. Bend the knees and waist and stay down through the shot. Play for a slice.
