The Soviet team with three world champions (reigning champion Karpov, future champion Kasparov and former champion Tal) were back in their usual form and this time left no doubt about the outcome. In the end, they only drew one match (against the Netherlands; and won the rest) and finished no less than 6½ points ahead of runners-up Czechoslovakia. The United States took the bronze medals.
Off the board, FIDE elected a new president at its congress held concurrently with the Olympiad. Friðrik Ólafsson of Iceland was succeeded by Florencio Campomanes of the Philippines.
Open event
A total of 91 nations played a 14-round Swiss system tournament - 93 had applied, but Gambia and Mauretania never showed up. To make for an even number of teams, the Swiss hosts also fielded a "B" team. For the first time, the two British Channel Islands, Guernsey and Jersey, participated with a joint team.
In the event of a draw, the tie-break was decided first by using the Buchholz system, then by match points.
Individual medals
Women's results
45 nations were signed up, and to make for an even number of teams, the Swiss hosts also fielded a "B" team. However, the Dominican Republic never showed up, so the competition ended up consisting of an odd 45 teams after all.
In the event of a draw, the tie-break was decided first by using the Buchholz system, then by match points.
Like the open event, the women's tournament was dominated by the Soviet Union, captained by world champion Chiburdanidze, who won the gold medals by a three-point margin. Romania and Hungary took silver and bronze, respectively.
