Explain the Handicap System to a New Golfer

You have started playing golf and everyone talks about handicaps as if it is obvious, which it is not. This explains the World Handicap System practically: what a handicap is, what it lets you do in competition, and roughly how the index is worked out, without the maths. Good for a new golfer who wants to follow the conversation and enter a club competition without bluffing.
