This is the story:
Five hundred twenty five chess experts gathered in Rabin Square in Tel Aviv Thursday to play against Israeli chess champion Alik Gershon. Gershon was attempting to set a new world's record for simultaneous chess game playing, a record currently held by Iranian champion Morteza Mahjoob. In order to beat Mahjoob's record, Gershon had to win more than 80% of the games he played in a period of 18 hours. All contestants had been ranked by the Israel Chess Federation.
