This possible lay of the cards was first analyzed and named by Mr. George Sturgis Coffin, born in Waltham, Massachusetts, United States, on September 8, 1903, and died on March 12, 1994. He was the author of more than 100 publications about the game of bridge. He was a graduate of Harvard in the year 1928 and, as an avid bridge player and theorist, was awarded the winner of The Bridge World international problem solving contest in the year 1931, which is when the game of duplicate bridge was in its infancy.

Mr. George Sturgis Coffin was not only an author on the game of bridge, but also a publisher and a distributor of bridge publications, even bridge equipment such as cards, tables, etc. His devotion to the solving of particularly difficult play techniques such as double double problems, coups, eliminations, and especially squeezes earned him the nickname of Endplays Coffin.

Note: Any additional information about Mr. George Sturgis Coffin, especially photographs, would be greatly appreciated.

Note: The student of Mr. George Sturgis Coffin can review a collection of his double dummy problems and participate in their solution on the website of Mr. Hugh Darwen. This collection was last modified as of the date of June 24, 2007.

The following publication, authored by him, is perhaps his best achievement, This book was published many times owing to its expert presentation. The photograph is of the publication printed in the year 1981 and is the 6th Edition as published by Dover Publications, ISBN: 0486242307, LC: 81069898.


Example of a Hexagon Squeeze

The designation of a double guard squeeze refers to a play technique, in which each of the three menaces is protected by both opponents.


South, as the declarer, leads the Ace. In this position West must discard a Spade, otherwise West unguards his Heart suit and/or Diamond suit. South discards the Diamond from the dummy.

However, East is squeezed in all three suits. If East discards the Ace, then South can win a trick with Queen in dummy, since West has discarded the King. If East discards the Queen, then South successfully finesses West for the King.

If East discards a small Diamond, then the two-card Diamond holding of South become automatic winners. Whatever East discards, the declarer is assured of the last four remaining tricks.
