GOLF TIPS FROM THE PROS Left-arm swing Although the potential reasons for a duck-hook are numerous, the following drill can help in avoiding the left side of the golf course. Try swinging the golf club with the left arm only. After a few free swings, try hitting golf balls with the left-arm swing, with the intent of taking away an over-active right side. Chip 'em low Next time you're practicing the chip shot, try this drill. Lay your golf bag in front of the hitting area and try to chip the ball low enough to hit the bag. Once you can do this without trouble, take the bag away and chip at the hole. This will allow you to get the ball started correctly on the bump-and-run shot. Keep your chin up The frequently given, but rarely asked for, advice of "keep you head down" is misleading. More accurately, keep your head behind the ball at impact, and keep your chin up. This provides a pivot point from which to generate leverage. And by keeping your chin up, your shoulders will rotate more easily, thereby creating a powerful coil.
