Following is a description of various events which may be held. Events not specifically listed may be approved on an experimental basis by the ACBL Tournament Department.
A. OPEN EVENT
There are no restrictions on age, gender or masterpoint holding on players either individually or collectively as members of a pair or team in open events.
For the purpose of computing masterpoints, open events may receive credit for tables entered in a concurrent same type event that is restricted. See Chapter 2, Section Three.
B. FLIGHTED EVENT
Individual, pair or team events may be subdivided into two or three “flights” having designated upper masterpoint limits. Approved masterpoint limits are listed at the end of this Chapter.
Participants may enter any flight for which they are eligible, playing only against players in their own flight. Masterpoints are awarded based on the number of tables in the flight entered added to the number of tables in all lower flights. These events may be playthrough or qualifying. However, it is recommended that only the top flight be run as a qualifying event. Flight C events may also be stratified.
C. STRATIFIED EVENT
Individual, pair or team events may be subdivided into two or three strats with specific lower and upper masterpoint limits. Participants enter the lowest strat for which they are eligible as they compete for awards in their own strat and all higher strats. Awards are based on the number of tables in the strat entered added to the number of tables in all lower strats. Stratified events may be run as playthroughs only.
In stratified events, the stratification level of a team or pair may be based, at sponsor option, on the average masterpoint holding of the team or pair. This option may be exercised in both club or unit games, and tournaments but not in qualifying events.
D. STRATIFLIGHTED EVENT
A stratiflighted event is a combination of flighted and stratified. The first group would have no masterpoint restrictions, unless the sponsoring organization chooses to stratify the top flight into strats (up to three, A-1, A-2, A-3). When the top flight has two or three strats the A-1 strat will have no masterpoint restriction while the A-2 or A-3 strat would have no lower masterpoint limit and an upper masterpoint limit of 1250, 1500, 2000, 3000 or 5000 (at least 500 points higher than the lower flight) at sponsor option.
The second group would be subdivided into two or three strats with specific lower and upper masterpoint limits. Participants may enter either the unrestricted group or the lowest strat for which they are eligible in the second group. Only the unrestricted group may be run as a qualifying event. At a sectional tournament the A and B flights can be combined into a group to play together with the C flight playing separately.
In stratiflighted and limited pair and team events, once the flight of the pair or team is determined, stratification within each flight may be based, at sponsor option, on the average masterpoint holding of the team or pair.
E. HANDICAP EVENT
Matchpoints or IMPs are given to participants as handicap points based on a predetermined scale for the type of event. Information for methods of computing handicaps may be obtained from the ACBL Tournament Department, the area Field Representative, or the director assigned to be in charge of the tournament.
F. BRACKETED EVENT
Knockout Team and Swiss Team events are divided into groups based on either the average or total masterpoints of the top two masterpoint holders or on the average masterpoints of the entire team. The tournament director-in-charge may be consulted for further information.
G. MASTERPOINT-RESTRICTED EVENT
All masterpoint-restricted events having an upper masterpoint limit require that all entrants be below that masterpoint limit. If an event has a lower masterpoint limit, one member of each partnership must meet or exceed the minimum limit. In an event designated as a Life Master event, all entrants must have attained their ACBL Life Master status. Exceptions may be made for entrants from other recognized organizations.
H. SIDE GAME SERIES
A side game series may be held as a pair game only. It is a series of at least three one-session games which may not be restricted by age, gender or masterpoint holding. The event may be stratified for side game session awards only, and may not be flighted. Participants may enter as many scheduled sessions as they wish, playing with the same or different partners each session. Overall ranking is done on an individual basis by computing the sum of each participant’s two best games. Awards are computed on the average number of tables entered in the two largest sessions. Gold points are awarded at regionals to overall winners at 80% of an open pair event. Gold points are awarded for section top placing only to participants who enter at least two sessions of the same event. Each session of the side game series will award single session side game overall awards (red points only). Each individual session may be stratified.
I. CHOICE PAIRS EVENT
A Choice Pairs event may be held as a pairs event only. It is an event scheduled for three sessions during one calendar day (morning, afternoon and evening) and a pair must choose to play in only two of the three sessions.
J. COMPACT KNOCKOUT EVENT
A bracketed knockout event in which each match is half the normal length (i.e., at least twelve and probably not more than fourteen boards) is an approved tournament event. This event is permitted at sectionals, for silver points, and at regionals for red and gold points (a minimum of nine teams is necessary to award gold points).
