If your ball is sitting down in high rough, you will have to chop it out. In order to chop it out, you will need to create a steep angle into the ball by making a steep back swing. Use your most lofted wedge. Open the club face then position the ball in the front of your stance and put more weight on your front foot. The more you open your stance, the less the ball will roll out once it is on the green. Use a firm grip with your forward hand so you can power through the grass. Hinge the club straight up with your wrists on the back swing then pull the club down.It's OK to hit it a touch fat, just make sure the heel of the club leads the toe to the ball. It's a crisp chop with a firm top hand. Swing on your toe line with very little follow-through.
