Morteza Mahjoob breaks Guinness Simultaneous Chess World Record
The Guinness World Record for the largest number of simultaneous games played
in a single session was initially set in 1996 Swedish Grandmaster Ulf Anderson,
who took on 310 opponents. This record was broken in 2004 by British IM Andrew
Martin, author of many of our openings
training DVDs. Martin played against 321 opponents, scoring 294 wins, 26
draws and 1 loss for a winning percentage of 95.64%. In August 2005 GM Susan
against 350 players simultaneously at the Gardens Mall in Palm Beach Gardens,
Florida. Finally, in February this year, Bulgarian GM Kiril Georgiev played
exhibition against 360 opponents.
The latest record attempt by Iranian GM Morteza Mahjoob
Recently Iranian GM Morteza Mahjoob, 29, took it on himself to break this record
– actually smash it to little pieces. He planned a simultaneous exhibition
against 500 players, which entailed walking for about 40 kilometers and staying
awake and sharp for up to 24 hours.

Just after midnight there were 130 players left. Many of them had no chance
of winning, but they insisted on
playing on. There were some kids and semi-professional teenage players who resisted
for more than 15 hours.
Their parents helped them by massaging them. Some of the players who hung on
for 15 hours needed medical attention. One of Morteza Mahjoob's chess students,
who is six years old, won his game against his teacher. This kid was amongst
the last ten players in the simul.
