Six Israeli chess masters who took part in the recent Chess Olympiad in Buenos Aires returned to Israel in a jubilant mood. “We have placed Israel on the international chess map,” they said. Israel won the fifth place in the Games, a place never before reached by an Israeli chess team. The six Israelis are: Yedael Stepak, Vladimir Liberson, Shimon Kagan, Nathan Birenbaum, Yehuda Greenfeld and Yaacov Blaiman. They said they had social meetings and talks with chess players from the USSR, Soviet bloc countries and China.
