What are ABA Daylong Tournaments?

ABA daylongs are the American Bridge Association sactioned variation of our popular daylong tournaments. You can register, play at your own pace, leave the table, then resume the game later during the day without losing your results. You'll get the final results the next day in a BBO mail, and in the list of Completed tournaments.

Game specifics:

• 8 boards, Matchpoints or IMP scoring
• ABA daylongs utilize advanced robots
• Once you begin, you have until midnight US Eastern Time to complete the tournament.
• American Bridge Association masterpoints and BBO points awarded.

Each table consists of a single human player, sitting South, and three robot players sitting in the other three seats.

Results
Results will be sent to your BBO Mailbox or they can be accessed in Recent Tournaments, in the History tab, once the Daylong is completed.

Best Hand
The human player is usually dealt the "best hand" (defined as the hand with the most high card points) at the table unless otherwise stated. Always having a good hand makes bridge more exciting and fun for most players!

Human Declares
The human player is switched into the North (Robot) seat whenever North is the declarer. The human player then declares the hand. When the hand is over, the human is switched back to his original seat.

Deal Pool
For every board in a Daylong tournament, we deal multiple instances. (ie Not everyone gets the same board 1, board 2, etc.) This is an anti cheating measure.

About the robots
The robots used on BBO are called GIB (Ginsberg's Intelligent Bridgeplayer). You can find out more about GIB's bidding system by clicking here.

The GIBs used in BBO play a relatively simple and natural 2/1 bidding system. You can find out the meaning of any bid by clicking on that bid as it appears in the bidding diagram. Furthermore,when it is your turn to bid, moving your mouse over the buttons for the various possible bids will cause an explanation of the bid you are considering (as your GIB partner will understand it) to be displayed. These explanations can be somewhat cryptic, but reading them carefully before you bid will help you to avoid misunderstandings with your GIB partner.
