Qualification and format.
The leading 18 available players from different countries in the Official World Golf Ranking on 11 September 2006 qualified automatically. These 18 players then selected a player from their country to compete with them. The person they pick had to be ranked within the top 100 on the Official World Golf Ranking as of 11 September 11. If there was no other player from that country within the top 100, then the next highest ranked player would be their partner. World qualifiers were held in October 2006. Six countries earned their spot in this way, four from the Asian qualifier and two from the South American qualifier.
The tournament was a 72-hole stroke play team event with each team consisting of two players. The first and third days are fourball play and the second and final days are foursomes play.
