The “Great 88” Conspiracy

The first 88 problems in Double Dummy Bridge, all five-card endings, were an attempt to illustrate all the possible endplay techniques. Dubbed the “Great 88,” these mini-problems were divided into five “Tribes” according to the kind of endplay, though the categorization was a bit fuzzy and Coffin chose to fudge with his title of Tribe 5. Nonetheless, the work is a significant contribution to card-play theory and its classical status is deserved.

Here are some curious facts:

Being a puzzler at heart, I won’t reveal the culprits; but I have presented the “Great 88” here for your examination. Or, perhaps I should say, the “Great 85” plus three impostors. These are exactly as in the book, however, I corrected a few obvious typos in duplicated spot cards. Each ending is given a name to describe the technique involved (the terminology is Coffin’s, which may be archaic today), and you are told which suit is trumps (or notrump), the number of tricks North-South must win, and the player on lead.

So, if you have nothing better to do, you might want to play bridge detective. Can you find the three bogus endings? I won’t tell you the answer here, but I’ll give you a hint: Start from the end and work backwards. If you think you have found them, or gave up trying, you can e-mail me for the answer.

[Addendum, March 2001. Thanks to Jonathan Weinstein for discovering the second ending that is illegal (unreachable without a revoke). Originally, I had only noticed one.]
