The 33rd Chess Olympiad, organized by FIDE and comprising an open and a women's tournament, took place between September 26 and October 13, 1998, in Elista, Kalmykia, Russia. There were 110 teams in the open event and 72 in the women's event. The Olympiad was the first international chess event to be held at Chess City. Construction of the complex was not complete by the start of the tournament, and some FIDE members were concerned that the facilities would not be ready in time, including the airport, telephone system, player housing, and the "Chess Palace" to be used as the main playing hall. Reported human rights abuses by FIDE and Kalmykia president Kirsan Ilyumzhinov led to calls for a boycott from Valery Borshchev, a member of the Duma. The British government did not call for a boycott but confirmed "reliable reports of human rights problems" and suggested that Kalmykian authorities might use publicity from Olympiad participation by foreign teams for its own purposes. Three nations were signed up but chose to stay away: Denmark, Norway, and Slovakia. The opening ceremony took place as scheduled, but the Chess Palace was still covered in scaffolding and was missing many windows. The first round was delayed, one free day was eliminated, and the tournament was shortened to 13 rounds from the planned 14. The organizers worked around the clock and playing conditions improved as the tournament progressed, although the main playing hall was not properly heated. Living conditions, food and drink, and telephone service were generally reported to be acceptable. Both tournament sections were officiated by International ArbiterGeurt Gijssen. Teams were paired across the 13 rounds of competition according to the Swiss system. The open division was played over four boards per round, whilst the women's was played over three. In the event of a draw, the tie-break was decided by 1. the Buchholz system; and 2. match points. The time control for each game permitted each player 100 minutes to make the first 40 of his or her moves, then an additional 50 minutes to make the next 20 moves, and then 10 minutes to finish the game, with an additional 30 seconds devolving on each player after each move, beginning with the first. In addition to the overall medal winners, the teams were divided into seeding groups, with the top finishers in each group receiving special prizes.
Open event
The open division was contested by 110 teams representing 106 nations. Russia, as hosts, fielded an unprecedented four teams, whilst the International Braille Chess Association provided one squad. Even without their strongest players, the "Three Ks", Russia were still favourites, and the team did win their fourth consecutive title. The United States improved another spot from the previous Olympiad and finished second, and Ukraine took the bronze medals, beating Israel on tiebreak.
The women's division was contested by 72 teams representing 69 nations. Russia, as hosts, fielded three teams, whilst the International Braille Chess Association entered one squad. China finally broke the Eastern European dominance by winning the title, led by former world champion Xie Jun and future champion Zhu Chen. Russia took the silver, whilst defending quadruple champions Georgia had to settle for bronze.
The Nona GaprindashviliTrophy is awarded to the nation that has the best average rank in the open and women's divisions. Where two or more teams are tied, they are ordered by best single finish in either division and then by total number of points scored. The trophy, named after the former women's world champion, was created by FIDE in 1997 and awarded for the first time in Elista.
