In
2014 and earlier editions, the championship was a single elimination
match play event. A new format was introduced in
2015, and the championship now starts with pool play, with 16 groups of four players playing
round-robin matches, on Wednesday through Friday. The top 16 seeded players are allocated to the 16 groups, one in each group. The remaining 48 players are placed into three pools (seeds 17–32, seeds 33–48, seeds 49–64). Each group has one player randomly selected from each pool to complete the group. All group play matches are limited to 18 holes with one point awarded for a
win and one-half point for a
halved match. Only one player advances to the weekend from each of the 16 groupings. After all 3 rounds are played, if 2 or more players are tied for first place in their group, then they play a sudden-death
stroke play playoff, beginning on hole 1 and moving beyond if necessary. The winners of each group advance to a single-elimination bracket on the weekend, with the round of 16 and quarterfinals on Saturday, and the semi-finals, finals, and consolation match on Sunday.
