More than half of the 2008 participants were bridge players, partly because the World Bridge Federation transferred some important quadrennial competitions to the WMSG, especially the Open and Women flights of its World Team Olympiad.[a] In 2004 there had been in the main continuing events 72 Open and 43 Women “Olympiad” entries (national teams-of-four with six players on most squads). Under the Minds Sports rubric in Beijing there were 71 and 54 entries, about 700 players. The one-time, similar tournament with a 28 years age limit attracted another 400 players.
