Deceleration while chipping could result in a fluffed or stubbed chip shot and this will result in extra strokes. The trick is not to accelerate the golf club with your hands. Using your hands will only ruin the rhythm of any golf stroke and the results are usually not very good

How to get acceleration
Center your swing motion about two feet past impact to achieve the kind of smooth acceleration evident in golf swings of better players. In other words, imagine producing maximum arm extension and maximum club head speed two feet past the ball. In order to do this, your backswing will be shorter than your follow-through. This will automatically produce smooth acceleration through impact. Acceleration through impact is a good thing. A smooth acceleration is what you need to hit the consistently solid shots you desire.

What to do with an open face? Accelerate!
If you need to create a high-lofted lob shot that will fly to the hole and stop, use an open stance and clubface use a three-quarter backswing and a full finish. The club head MUST accelerate through impact for any open face shot. How do you guarantee you will accelerate the club head? Your follow through must be longer than your backswing was.

Set your golf shot plan
You first need to plan the type of golf shot you will be able to execute the majority of the time. Your golf shot plan should include where the golf ball lands on the putting green. This spot should be as flat as possible. If you attempt to land your golf ball on a hill, any mistake that make will be amplified. If you land it short of your target into a hill, obviously the ball will be stopped sooner and will not roll out as far.

The opposite is true if your mistake is past your target. Your golf ball will bound forward and roll out farther than you had calculated in your golf shot plan. If you have to land your golf ball on an uneven slope, it is better to use a valley or a swale. This terrain would have the opposite effect and would help any mistake that you make.
