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.
This new offering of ours is due to Gerben Dirksen, a good friend and bridge expert, who undertook to digitize the 1991 Bermuda Bowl final between Iceland and Poland inter alia because he wanted to see unusual systems in action; in fact, if I remember correctly, 1991 was the last time a highly unusual system was used in a world championship final -a Polish pair was using a Forcing Pass system. Note that Gerben has done a great job in providing explanations of the bids.
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.
For the 1991 Bermuda Bowl our source was the official book published courtesy of the WBF. Unfortunately, the editors of the book made the dubious choice to omit some "dull" boards from the tournament report, so the hand records are not complete (Edgar Kaplan had spoken strongly against this practice, which is no longer being used). When you see each player being dealt a whole suit, you'll know that this deal is missing.
For the moment we have but five segments but Gerben has promised to continue!
