Anatoly Karpov and Viswanathan Anand, two former world champions, took on dozens of children and teenagers in simultaneous chess games in Jerusalem on Monday as hundreds of onlookers watched.
The two grandmasters were visiting Israel as part of Jewish state's 70th-anniversary celebrations. Karpov faced 25 opponents and Anand took on 29 players outdoors in the afternoon sunshine with Jerusalem's walled Old City as a backdrop.
Russian Karpov, 66, was world champion in 1975-1985 and 1993-1999, and 48-year-old Anand, from India, ruled the boards in 2000-2002 and 2007-2013 before being succeeded by the current world champion, Magnus Carlsen of Norway.
