Israeli chess grandmaster Alik Gershon has taken the Guinness world record for most simultaneous chess games, stripping arch-rival Iran's current record-holder, Morteza Mahjoob, of the honor.
Gershon, 30, played 19-hours against 520 players finishing his games on Friday. Gershon won 454 (86 percent) of the games played, tied in 58 and suffered only 11 defeats as he topped the previous world record of 500 simultaneous games played at once.
The new world record holder had to undergo serious physical conditioning to last through the event and continually travel from board to board all night to make his many moves.
The match was sponsored by the Jewish Agency to commemorate the 20th anniversary of the massive aliya from the former Soviet Union, a wave of immigration that dramatically increased Israel prowess in competitive international chess.
