Daylongs are robot tourneys where you get up to 24 hours to complete your game. You can register, play at your own pace, leave the table, then resume the game any time during the day without losing your results. You'll get the final results the next day in a BBO mail.
Daylongs utilize advanced robots and award BBO Points if you do well. With no cap on the number of players, points awarded are also correspondingly much higher than in other tournaments.
Each table consists of a single human player, sitting South, and three robot players sitting in the other three seats.
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.
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!
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.
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).
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.
