Please see my short-game article below in the July 2011 Golf Punk magazine (中文版：世界高尔夫2011年7月总第64期, 切杆技巧原则)。
Not all of our chips will be from the perfect lie on the fringe, so we need to make sure we practice out of a variety of lies. Next time you practice your chipping, drop your ball in some rough and try to recreate more realistic lies. Here are a couple things you should change in your chipping when you encounter a tough lie in the rough:
Use more a little more loft then you normal, the extra loft makes it a little easier to get down to the ball and to get the ball up and out of the rough.
Feel like your backswing is more to the outside, this helps us get a little steeper angle of attack back down to the ball
Keep the weight left—this is important for all chip shots, but an absolute must when we get into a tough lie.
