The rules
Every golfer plays his own ball. Each group is a team of four, and the teams play against the rest of the field. On each hole two scores make the team score.
The organiser can set the anchor to play off net or gross. Whichever it is, the best of the other three is taken the same way.
The anchor order
The group agrees the order on the first tee, and it repeats every four holes. It doesn’t have to match the order you tee off in. Once the first score is in on the 1st, the order is locked.
Eighteen holes don’t divide by four, so the first two golfers anchor five holes and the last two anchor four. Groups usually put their steadiest golfers first. To even it out, the organiser can drop the anchor on the last two holes.
Holes 17 and 18
The organiser picks one of three finishes before the round.
Scoring and the money
Scoring it without a spreadsheet
Halved tracks the anchor for every group: who anchors each hole, which net counts with him, and where every team stands.
Everyone knows whose hole it is.
Free for the field. Halved tracks every group’s anchor, picks the counting net, and pays the winning team.
