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.

Daylongs cost 39 cents, 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.

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. This game is Not Best Hand.

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. If you’d like to get an idea of how you got on before then, you can check the provisional leaderboard in the list of Completed Tournaments.

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 (not everyone gets the same board 1, board 2 etc). This helps to prevent cheating.

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 see the meaning of any bid by clicking on the bid in the bidding diagram. When it’s your turn to bid, you’ll see an explanation of each bid (as your GIB partner will understand it) by moving your mouse over the possible bids. These explanations can be somewhat cryptic, but reading them carefully before you bid will help avoid misunderstandings with your GIB partner.
