If you are faced with a high bunker, take this one for example, the lip is as high as my head, I need to get the ball up real quick and stop it quick. If I have a lob wedge that would be a good club for this because it is not that long a bunker shot. If you do not carry a lob wedge and you use a sand wedge, you want to open the face more on the high bunker shots. As you open the face you want to stand a little farther from the ball so that when you bend over you are a little wider and your hands are lower. In that position you have the best chance of hitting the high bunker shot. Wider stance, hands low, face well open. It looks something like this. The ball is forward, almost off my left instep, my hands are low, I am farther from the ball and wider. The swing looks like this. Notice how that ball got up very high, landed very soft, rolled very little. That is necessary when you have this situation where the bunker is over your head. It takes a pretty big swing, that was almost a full swing, but that club slipped right under the ball taking the right amount of sand and producing the exact shot I wanted.
