Successful results when chipping, especially from a tight lie, rely on us using the bounce on our wedges correctly. By this, we mean gliding the club underneath the ball using the loft on the club to get the ball in the air.
So in your pre-shot routine, try to both hear and feel your wedge skidding along the ground. The goal is to then replicate this feeling on the shot, rather than focusing too much on the ball. Do this, and the strike will take care of itself.
