Mysteries

These oddball or unusual problems are open questions, old or new, in search of new or better solutions. Fans have already provided answers or improvements on earlier results in several of those published here. You can try your own detective skills, then compare with what others have done. Perhaps you will be a new record-setter yourself.
To propose a solution, add information, or contribute to the discussion, read the accumulated discussion, then send e-mail to: editor@bridgeworld.com

We will present the discussion of progress in solving the mystery as it occurs, and results and discussion of each mystery will be summarized one year after it is presented, on New Year's Eve, when the next mystery is presented.
