Chipping is a whole 'nother situation. Notice the guy behind me, looks like he's trying to "scoop" the ball up in the air with his right hand. Then his left wrist buckles. The timing has to be perfect each time, otherwise he'll get inconsistent contact. I try to imagine hitting down on the ball with my right index finger and make sure my left wrist stays flat past the ball...or the back of my left palm hits an imaginary wall two feet in front of where my hands are at address.
