An ACBL-wide event is a one-session game that has a sectional open pair rating. Most of these games utilize computer-generated hands. When computer-generated hands are used they are played simultaneously at numerous sites through out the entire ACBL territory. Non-participating bridge experts study these hands (but do not alter them) and predict the probable results from playing them. ACBL publishes these predictions and the analyses on which they are based. This information is available to all contestants upon completion of the game. All open games receive sectional-rated masterpoints.
ACBL-wide special games may not be conducted during any month that is designated as a special fund month. Currently, the months of January (Junior), April (Charity), May (Grass Roots) and September (International) are designated as special fund game months.
