This is the scoring format used in all Ryder Cup matches.
It means that each hole is decided in isolation, rather than strokeplay, which is the cumulative scoring method used in most golf tournaments, including all four Majors.
In other words, the scores from every hole are not added together to make up a player's total score in matchplay.
The holes are played individually and whoever takes the fewest shots, wins that particular hole.
If the players on opposing teams have the same low score, the hole is halved.
Once the match is completed, a point is awarded to the winning team. Where matches finish all-square with no-one leading, a half point is awarded to each side.
