Standard chip techniques say to use an open stance and play the ball back of center to promote a descending strike. This may work for most golfers, but many have problems skulling or chunking the ball and also have poor distance control with this method because the ball takes off too low and too hot. Here is an alternate method for those experiencing this type of trouble:

Try a closed stance with a ball position forward of center, and use a pronounced forward press. This allows a descending strike with less chance of skulling or chunking. For distance control try using the same comfortable backswing all the time (maybe 2 or 3 feet long), but just change clubs depending on the desired distance.
