Firstly, any particularly bad holes, where you play more than 2 or more over your awarded shots, you score 0. Bad holes do count against you because you score no points, but if you played +10 over you are not penalised like in Stroke Play.
Secondly, by awarding players shots on certain holes, everyone, whatever their standard can play together. It’s the total points of the round which determines the winner and not the number of strokes.
Thirdly – It’s a great way to improve your game. For example, on a difficult Par 5 hole, an 18 handicap player will know that he can play +1 (6 shots) to score 2 points and therefore, they can pretend it’s a Par 6, and play 4 to reach the green. For the same player, a long Par 3 could be played as a Par 4 and still get 2 points. It helps treat the more difficult holes with more respect and can help the way we approach each hole and our game
