The Auckland International badminton tournament will be used as a guinea pig, testing a new points system for the first time.
The tournament, starting tomorrow, is also the start of a three-month trial in which the sport will shift from a best of three sets, first-to-21 points system to best of five and first to 11 points.
Every point will count, instead of only those scored when a player is serving.
Also gone is the rule under which at 20-all, a player must win by two points. Instead, at 10-all the next point will win the set.
The total number of points in a match drops from 42 in a straight sets win to 33 over three games.
