The Zenith Daylong Reward is where serious bridge meets your schedule. You get 16 boards, scored in matchpoints and you can play anytime over 24 hours. It’s the most respected daylong on BBO, with bragging rights and BB$ prizes on the line. More players means more to win — so jump in, play your best, and find out where you stand.

Format

• 16 boards, Matchpoints scoring
• 52% payback in prizes distributed to the top 40% finishers
• Win BBO Points and BB$ Prizes

Each human player sits South, partnering an advanced robot, and plays against two robot opponents. Everyone competes under the same conditions — with the same partner and opponents — making this format a true test of individual skill.

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. You can also see your provisional results as soon as you finished playing your boards, and check back for updates in the list of Completed tournaments.

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.

About BB$
