Most bridge sessions played at both club and tournament level of affiliated clubs, are played for Master Points. If you finish in approximately the top third of your field, you will receive Master Points. Master Points are only awarded to events run by an affiliated Club, Region, or NZ Bridge. There are 3 categories of Master Point awards:
Awarded to players who finish in the top placings of approved A point tournaments along with winners of all session of Pairs Tournaments and fractional A points to the winners of each match in Match-Play (teams).
Awarded to players who finish in the top placings of approved B point tournaments along with winners of all session of Pairs Tournaments. B points cannot be converted into A points.
Awarded to players who finish in the top placings of approved one session C point events. C Points are converted to B Points in the ratio of 100 C Points to one B Point.
