Played annually, this special open server event is named in Herbert W. Gustafson's honor. When Mr. Gustafson passed away in 2008, he left a bequest to CCLA to support chess events like this, a semi-class event with sections of four players with two games per opponent. All games will be by server, with no chess engines allowed. The tournament is open to all residents of the United States and its territories, with no CCLA membership requirement and no entry fee. The prize for winning a section will be a $20 credit that can be used only for CCLA membership dues or, for CCLA members, as entry fees to CCLA events. Section prize is split in the event of a tie. Games also count towards your annual Grand Prix score.

Time limit: 10 moves/30 days.
