A chip shot involves precision to control the correct yardage and distance to leave the shortest possible putt. Because this shot involves a relatively short swing, there is little time for compensations, therefore the set-up and the fundamentals need to be correct.  The key is to find a way to control the clubhead with the body, not the hands, while hitting the ball the correct distance.  Here are a few fundamentals to help you with your chipping technique:

Less air time, more roll – example: roll balls can control roll more than air
Feet close together-Keeps body more quiet
Weight towards front leg-hands pressed forward
Ball position is in the center or towards back foot depending on the lie
Use a putting stroke-straight back and through
Try to achieve a slight downward brush
Use slightly tighter grip pressure
Hold finish-don’t let wrists flips
