One of the biggest mistakes that happens in the short game for chipping is the break down of the left wrist, where the right hand tries to scoop the ball up. Ask your pro and he will tell you that is the one that happens the most often.
#1 Chipping Mistake
People try to elevate the ball when actually if they would simply let the club elevate the ball they would be a lot better off. Sometimes I have told people to imagine that they are swinging and they are going to deloft the club a little bit. Get the feeling that they are coming in with their right wrist cupped backwards than forwards. We have tools to help you with this.
Improve Chip Shot: How to Use the Tac Tic Tool
One of the most fun tools is Tac Tic, you put it on the left wrist and when your right hand tries to flip the club this is what happens, listen, it clicks. You get instant feedback, when your left wrist breaks down you feel it and you can hear it. Wonderful, fun little device. I teach with it and I put it on people and I turn my back when I am working with someone else and I hear this click, and I say uh-oh, you made a bad swing. So it gives you feedback which you need.
You can also use a training device like this one; it is a wonderful tool for full swing as well as chipping and pitching. It is the key, you put it on your right hand and strap it around and it will give a little bit but it won't allow you to force your hand through where you scoop the ball. These are little products from Golf Around The World that will help you with your chipping and short game by keeping you from doing one of the most obvious and worst of all the mistakes in chipping, and that is left wrist breakdown.
