Double Dummy Corner was started in January 2001 for the benefit of people interested in double dummy bridge problems. Its main purposes are
It is updated every Sunday, in principle, subject to the vagaries of the webmaster's personal life.
As a matter of policy I provide solutions only to Competition Problems (usually shortly after the closing date), but you can send me a solution to any problem and I will reply (not always immediately!) telling you if you are right or, if you are not, where your solution goes wrong. If you are right and it is your first attempt at the problem in question, then I add your name to the list of solvers for that problem.
Nowadays these problems can be solved by computer programs; indeed, I use such a program myself to check all the problems that appear here and to check submitted solutions. I assume unless you tell me otherwise that your solutions result from your own mental efforts, not assisted by any computer program.
My archive of previously published problems is divided into two sections.
The first section currently has 501 problems and consists mainly of problems that appeared in solving competitions British bridge magazines from 1949 to 2005. (The highest problem number is currently 512, but there are some gaps and there are some duplicates that came to light after their appearance here.)
The second section, consisting of problems collected by George S. Coffin during the middle of the 20th century, is complete and has 304 problems. Every problem is checked by a computer, which has so far caused me to discard 212 as being "cooked" (though in many cases nobody seemed to notice when they were first published). I found 77 cooked problems in George Coffin's two books, out of 413. Several of these cooked problems are given high accolades by Coffin. Of the 635 problems published in my magazine column and, before me, Ernest Pawle's, 135 were cooked. It all goes to show just how tricky this business is!
In addition to the main repository, there is a section entitled Mistakes From The Media giving some interesting examples of incorrect double dummy analysis by prominent bridge writers. Yet another section, Exchange & Win Problems, is devoted to a comparatively new, intriguing kind of problem invented by Luigi Caroli.
Click on Competition Problem #1 if you want to have a go at one of the toughest problems ever composed. During the period at the beginning of 2001 when I had no magazine column, I started to place "competition problems" here. I only got as far as #2 (though much later added #3). In 2005 I lost my magazine column again and restarted competitions here with #4. Correct solutions to #1, #2, #3 and the current one on this page, sent by e-mail, earn D.D. Master Points.
Richard Pavlicek has composed some nice problems that you can find at his web site.
