The 29th Chess Olympiad, organized by FIDE and comprising an open and a women's tournament, as well as several other events designed to promote the game of chess, took place between November 16 and December 4, 1990, in Novi Sad, Yugoslavia (present-day Serbia).
This time around, the political controversy surrounded the Baltic states – Estonia, Latvia, and Lithuania – who had all recently declared their independence from the Soviet Union and wanted to send their own teams to the Olympiad. The Yugoslavian hosts, however, followed the decree from Moscow and refused to accept their entries. Despite a petition from several top players they weren't allowed to play. This meant that big names like Jaan Ehlvest, Lembit Oll, Alexei Shirov, and former world champion Mikhail Tal could not appear at the Olympiad.
Incidentally, this would also turn out to be the last Olympic appearances of the "old" Eastern Bloc countries: East Germany, Yugoslavia and the Soviet Union. The latter finished in style by winning their sixth consecutive gold medals and 18th overall, even without Garry Kasparov and Anatoly Karpov who were in the midst of their fifth and final world championship match. Instead, the last Soviet team was led by Ivanchuk and Gelfand – two of the co-signers of the pro-Baltic petition. They still won in style, well ahead of the United States and England.
