Clubface opens at impact or needing a low trajectory.
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.
Difficulty deciding how to play based on the specific conditions of each shot.
Trees, bushes, or other obstacles that can prevent you from addressing the ball. This is great if you would rather get the ball out and a little further away than you would if you had to take an unplayable lie.
You need to bounce the ball to the green when a bushes or trees are obstructing the lob shot or if a bump and run would leave the ball in the long rough. The Texas Turn Down can land the ball short of the green with enough over spin to bounce forward and run close to the pin.
You are worried about getting a strong downhill roll.
Restricting your swing while chipping, not enough loft, or easing into the ball.
The range of error for a forty yard wedge shot is huge because you can finish your shot between thirty five yards short of the target or sixty yards past it.
