There is a procedure for each swing. First, you explore the course to see where you are heading. Next, you choose one of the 13 golf clubs. They all have a different strengths and some are specifically to be used to get out of a bunker or past trees. While aiming, you have to take the direction and the force of the wind into account, as shown in the top right corner. The force of the hit is determined by pressing a button at the right time while a cursor is hovering over the power bar, and you do the same to choose the desired effect.
Once you get on the green, a close-up is shown and only a single club is available. At this point, you can still choose the direction, force and effect, but you no longer have to consider the wind, only the slope. Some courses allow for hole-in-ones.
