Bunkers
If you find yourself in one of the numerous deep bunkers on these courses, use the high-sand lob on the Shot Designer screen to get out. These are evil bunkers, and just getting out is a tough job. You'll also find the "bump-and-run" shot very useful on St. Andrews--especially on windy days.
Get the hang
When first playing the game, start with the Novice level at St. Andrews. This is a much easier driving course than Royal Troon, and you won't have to spend all day in the rough while you get the hang of the swing mechanism.
