[a] It is contested every odd-number year under the auspices of the World Bridge Federation (WBF), alongside the Bermuda Bowl (Open), Venice Cup (Women) and Wuhan Cup (Mixed).
The d'Orsi Senior Bowl is also the trophy awarded to the winning team.
[c] They compete as teams-of-four with scoring by International Match Points (IMP).
A short exhibition for Seniors was added to the program, as was the (third) World Computer Bridge Championships.
[6] The two Austrians and two Israelis had played on both winners of the (transnational) World Senior Teams Championship, 1994 and 1998, with one of the two Bulgarians as a teammate in 1998.
Thus all participants were able to enter the Transnational Open Teams contested during the second week of the main events.
Only Poland and France scored better than average (150 Victory Points, equivalent to ten ties) followed by China, North America, World Champions, and Australia.
Three Americans in different combinations won three apiece: Roger Bates, Grant Baze, and Garey Hayden.
22 teams France won the 2011 d'Orsi Bowl by 165 to 160 IMP in a two-day final match against USA 2,[25] the second of two qualifiers from the United States.
France yielded almost nothing during the first three segments, to lead overnight by 89 to 45+ including carryover.
The Americans posted a huge fourth set, 79 IMP on 16 deals to regain the lead, but France again yielded almost nothing in the last two segments, and only 75 IMP on 80 deals in the five good segments.
[27] The regular quota for Europe is six teams, seven at Veldhoven because the host country qualifies automatically.
The original winners, Germany, were disqualified, and the WBF moved USA 2 to first place, Poland to second and France to third.
Venezuela has represented South America (twice, 1966 and 1967) and Central American and the Caribbean (five or six of seven times, 1985 to 1997).[when?
Further, there may be only one entry from one nation, except that North America is permitted two from the United States in its quota of three.
North America does routinely pass on the nominations of two United States teams (selected by the USBF) and selects its third by a two-team "tournament" if Canada and Mexico both choose to enter a national team.
