1977 Bermuda Bowl

One of the objectives of the Vugraph project is to present great matches of the past in .lin or .pbn format, matches that were played long before computers became ubiquitous and whose hand records only existed so far in printed form.

The user must be aware of a fundamental difference of the reconstructed lin files as opposed to the regular Vugraph files: namely, regular Vugraph files are an accurate record of the bids and the cards played, down to the last spot card; on the other hand, records in books almost always are vague as to spot cards. Hence, when the book says "Declarer drew trumps in two rounds", we usually do not know if he played the ace first or the king, or if the defenders followed with this or that low card; and usually it does not matter. When it matters, sources usually provide the relevant information.

There is also another difference, concerning the scoring; in the 1977 match the pre-1987 scoring was used. The main difference from today is that the penalty for non-vulnerable undertricks was lighter: 100-300-500-700 and so on. In our presentation the modern scoring is used to score the individual boards but the carry-over reflects the actual score of the match.

For the 1977 Bermuda Bowl our source was the official book published courtesy of the ACBL. For the moment we provide only the final match between USA I (the Defenders) and USA II (the Challengers). In fact, this was the unique time in a Bermuda Bowl where two teams from the same country have met in the final -as this was deemed awkward, a rule has been promulgated whereby if two teams of the same country are present in the semifinals they have to play each other.
The two US teams had qualified 1st and 2nd respectively from a six team round robin - the other teams being Sweden, Argentina, Australia and Taiwan. The Defenders had a 31 IMP carry over (actually 30.5 IMP) from the RR and looked as if they would retain the title after 64 boards as they led by 44 IMPs. But the Challengers really came alive after that and outscored the holders by 73 IMPs over the final 32 boards to take the glory and the Bermuda Bowl.

This new offering of ours is, for yet one more time, due to Denis O' Kane. Kudos to Denis for another splendid job!


Vugraph aficionados will note that this new offering presents a new feature: the so-called "pf files" (see below) allow the user to depart at any time from the line of play followed at the table, to play out the hand all by himself and explore alternative lines of play. However, once you have departed from the original line, you cannot reliably revert to it unless you go back at Trick 1.

If you want, you can have here, all the .lin files zipped (without cumulative scores).

Here you can also find all six files in .pbn format (zipped) to replay with Jack, GIB or whatever.

Here you can also find all six files in .dup format (zipped) for duplication purposes.
