The rating for Carlsen stood at 2851.2 points in the unofficial live rating portals which means that the Norwegian has cracked the all-time high rating record of 2851 held by former world champion and his former trainer Gary Kasparov of Russia.
On what turned out to be a perfect opener, all the four games in the nine-players round robin tournament ended decisively and the biggest upset was recorded by Hikaru Nakamura of United States who defeated World number two Levon Aronian with black pieces.
With Nakamura calling the shots, Vladimir Kramnik turned out to be another winner of the day at the expense of world's top woman player Judit Polgar of Hungary. The all-decisive-games record was kept intact by a late-benefitting Michael Adams of England against compatriot Gawain Jones. World champion Vishwanathan Anand had a rest day in the opener as he drew number one in the official drawing of lots.
