What are Daylong Tournaments?

Daylongs are a new type of robot tourney 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.

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

Game Variations

There are different types of Daylong tournaments.

• MP daylongs are scored in MP.
• IMP daylongs are scored in IMP.
• Just Declare daylongs have predealt, prebid hands with players as declarers always. Just Declare Daylongs are not Best Hand.
• Multi-day survivor daylongs
• Multi-session daylongs
  

BBO Daylong Tournaments
BBO Daylongs are 8-board long and cost a small entry fee in BB$. They use advanced robots and award BBO Points if you do well. With no cap on the number of players, the BBO points awarded are much higher than in other tournaments.

What is "Just Declare"?
Just Declare is a special game format that tests declarer ability to the utmost. You are the declarer in every board, with hands predealt and prebid by robots. Play your best, your result is duplicated. Just Declare tournaments are Not Best Hand.

Free Daylong Tournaments

• We offer one Free Daylong every day (alternating between game formats). The Free Daylong uses basic robots and does not award BBO Points.
• Free multi-session daylong events are also available every weekend. Look for the Free Weekend Survivor, or the Free 2-Day Weekend Evente very Saturday.
  
• On Sundays, you can play the Free Super Sunday Daylong, which is open for registrations the entire week.

Tournament features

• Most daylongs are Best Hand: The human player receives the hand with the most high-card points at the table or tied for the most high-card points. (Best-hand is defined solely by high-card points and does not take into account hand pattern.)
• All daylongs are Human Declares: The human player declares for his robot partner when their side wins the contract.
• Daylongs may utilize Deal Pools: Not everyone will be dealt the same boards. This is a security measure.
  

Results
A provisional leaderboard is available while the game is in progress, in the list of Completed tournaments. Your final results will be sent to your BBO Mailbox or they can be accessed in Recent Tournaments, in the History tab, after the Daylong is completed.

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.
