Don't worry too much about what you think the ball should do...practice to get the feel and so you'll know what the ball will do. Notice your lie (lower right of screen), especially in the rough. The heavier the lie the harder the swing. And try hitting as close to a full swing as possible and swing harder than you think you should. To make a fuller swing, try different shots like full, flop, punch or pitch. Remember, Its better to be on the green then have another shot in the rough.
