Israeli chess grandmaster Alik Gershon broke the Guinness World Record in Tel Aviv early Friday morning for simultaneous games played, a title previously held by an Iranian chess player.

The thirty-year-old played 527 concurrent games, winning 87% of them.

Jewish Agency Chair Natan Sharanskey and several Knesset members turned up in Tel Aviv's Rabin Square to face off against the grandmaster in a game.

"It is a personal challenge," Gershon said while playing. He said he put himself through months of physical training for the competition which lasted over 19 hours.

The former record holder Morteza Mahjoob of Iran set the record in August 2009, playing 500 games over the course of 18 hours.
