At the 1984 Winter Olympics in Sarajevo, Yugoslavia, the Soviet Union won its sixth gold medal. Czechoslovakia and Sweden won the silver and bronze medals. The 1988 Winter Olympics were held in Calgary, Alberta, Canada, where the Soviet team captured its seventh and final gold medal. The Soviets' last Olympic game was a loss to Finland. The Finnish team was not considered a serious medal contender—it had competed in the World Championships since 1939 and had not won a single medal. However, Finland upset the Soviets 2–1 and won silver. The IIHF decided to change the tournament format because in several cases, the gold medal winner had been decided before the final day of play. During a congress in 1990, the IIHF introduced a playoff system. The new system was used at the 1992 Winter Olympics in Albertville, France. Preliminary round-robin games were held and followed by an eight-team cup-system style medal round that culminated in a gold medal game.
