Chess is a leading sport in Israel and is enjoyed by people of all ages. There are many Israeli grandmasters and Israeli chess players have won a number of youth world championships. Israel stages an annual international championship and hosted the World Team Chess Championship in 2005. The Ministry of Education and the World Chess Federation agreed upon a project of teaching chess within Israeli schools, and it has been introduced into the curriculum of some schools. The city of Beersheba has become a national chess center, with the game being taught in the city's kindergartens. Owing partly to Soviet immigration, it is home to the largest number of chess grandmasters of any city in the world. The Israeli chess team won the silver medal at the 2008 Chess Olympiad and the bronze, coming in third among 148 teams, at the 2010 Olympiad.
