Problems by and from Ivar Andersson

DDC Home Problem Archive First Andersson problem Last Andersson problem

Sweden's Ivar Andersson collected hundreds of problems during the first half of the twentieth century and in fact contributed all of the 201 double dummy problems appearing in George Coffin's "Sure Tricks" (1948).  These 201 include several ingenious miniatures composed by himself.  Unfortunately, it appears that Andersson did not faithfully record the authorship of all the problems in his collection.  Like George Coffin, I use "by Ivar Andersson" for problems actually composed by him and "from Ivar Andersson" for those he collected, whose composers must alas remain as anonymous as they were when Coffin published these problems in 1948.

Steve Bloom, U.S.A., became a composer of D.D. problems after discovering this web site.  He is a retired professor of mathematics, "with a bent toward the theoretical and impractical".  He adds, "This applies in bridge as well."  Many years ago he wrote a series of articles for Bridge Today, called "The Tell Principle", discussing a lot of really off-beat bidding ideas, such as transfers in competitive auctions, that have since gained some currency.

Tim Bourke is an Australian bridge player and writer. He is internationally renowned as a collector and composer of bridge hands, or deals, having composed most of those in David Bird's "Abbot" series since 1996. He also owns one of the world's largest collections of English-language bridge books, magazines and memorabilia.  As a player, he has won nine Australian national titles.  He has a degree in mathematics and is an expert in the obscure computer programming language APL and has written extensive bridge odds-calculating routines in that language as well as many bridge-related formatting routines. He is widely regarded as one of the world's most fertile composers of original single-dummy bridge problems.

Dr Ian Budden of England contributed some good problems in the 1980s and recently returned to the art.  He was for many years a senior administrator and legal adviser at the University of London, from which he retired at the end of 2012.  He started to play bridge at school in the 1960s, but had really learnt the rudiments of the game much earlier by playing in whist drives with his grandfather.  His interest in double dummy problems was kindled in the late 1970s by Hugh Darwen’s column in Bridge Magazine, and he readily acknowledges his debt to other authors, especially Terence Reese, and to Ottlik and Kelsey’s Adventures in Card Play.

DDC Home Problem Archive First Darwen problem Last Darwen problem

Hugh Darwen of England ... that's somebody I know rather more about than any other composer, but I'd better not say too much.  I have been composing D.D. problems since 1964.  My competition column in the UK monthly Bridge Magazine started in 1966 when I took over on the death of Ernest Pawle.  It subsequently moved several times to other British magazines and finally closed altogether in July, 2004.  My book, Bridge Magic, mainly a collection of puzzles from Bridge Magazine, was published in 1972.  As a composer, I have a special penchant for novel gambit plays.  (A gambit is the sacrifice of a winner.)

Problems by Paolo Treossi

Paolo Treossi one of Italy's leading bridge teachers.  He learned the game in 1981 but quit after playing rubber bridge for less than one year.  He returned to the game in 1991, playing at his local club in Faenza.  He eventually discovered my D.D. column, at that time in Bridge Magazine, and also became fascinated by Luigi Caroli's Exchange and Win puzzles, which inspired him to compose some himself.  He later moved to Forlì and in 2002 started a partnership with the strongest player at his new bridge club, which led to "drastic improvement" in his own standard.  In 2004 he was a member of the San Marino national team at the European Championships in Malmoe.  He is now president of the Forlì bridge club, whose bridge school, now with four teachers in addition to himself, is one of the most successful in Italy.

Problems by W.H Whitfeld

DDC Home Problem Archive First Whitfeld problem Last Whitfeld problem

Prof. W.H. Whitfeld of Cambridge, England, was a noted mathematician, some of whose problems appeared in the very first book of double dummy problems, Double Dummy Bridge by Ernest Bergholt, published by De La Rue in 1906, 20 years before the invention of the game, contract bridge, that was to supersede the "auction bridge" that had been invented in 1903 or 1904, in turn superseding something called "bridge whist".  Whitfeld was composing double dummy problems before the turn of the twentieth century.  Of course, double dummy problems are equally applicable to all versions of bridge, and also to whist, because the rules of card play are the same in each case.

I am most grateful to Wolf Klewe, who sent me the entry for Whitfeld, which I have copied here, from William Butler's Whist
