Which holes you get shots on, what score makes two points, and when to put the ball in your pocket.
Two points is par plus your shots: hole out in that many for two Stableford points, one fewer for three, one more for one. Pick up after that many strokes if the ball isn't in the hole: the next one scores nothing. Shaded holes are where you get your extra shot.
Lengths are metres off the yellow tees, as on the club's card, and the posts on the course are in metres too. These are your shots in the individual Stableford. The team match has its own, shown in the badges in the Captains' Room.
