You top the ball, hit it thin or fat when chipping due to an excessive wrist action. You might even notice the back of your forward hand collapse during impact.
You need to chip over the rough while facing a sidehill, downhill shot about 40 feet away from the pin.
You lose distance and make large divots because you are cocking your wrists too much when using your lob wedge.
You need a lot of spin to help the ball land on a narrow green or a sharply inclined green. You might need just the opposite, less spin with extra roll because you are unable or it is unsafe to aim at the pin directly.
It is too windy to risk chipping onto the green. You might be afraid the ball will roll too much away from the hole because the grass is cut too short, the ground is firm, and dry.
A skulled chip or pitch due to hitting the ball on the bottom of the club instead of the clubface. The clubface makes contact below the equator on the ball and causes a low line drive. Anxiety will cause you to want to look up too soon and cause poor contact with the ball.
Poor chipping and iron play from just off the green.
Unable to determine how to play your ball when in the fringe.
Needing maximum amount of spin with a lot of loft.
Wedge shots that fly short and unpredictably.
