'The challenge of pitting yourself and your skills against every other person on the planet may be many people's worst nightmare... but for Magnus Carlsen, it's a dream.' Or, at least, it was a dream. On 10 September 2010, in the penthouse of the Copper Square Hotel in New York City, 19-year-old Carlsen took on an online team of global chess players led by three grandmasters, these being Frenchman Maxime Vachier-Lagrave, American Hikaru Nakamura and Hungarian Judit Polgár. Global chess fans voted on the moves suggested by the three grandmasters, with the consensus vote choosing the next move against Carlsen. Maurice Ashley and Garry Kasparov were also at the event to provide feedback and insight. Though an exciting event, the rules were quite complex. Carlsen played on a physical chessboard and had no access to external support. The three grandmasters were stationed in a different location and suggested their moves via computer. A butler, present in the penthouse, played the chosen moves of the World Team on Carlsen's board. The only contact between Carlsen and the three grandmasters was through an arbiter, who assisted both sides in the running of the challenge and ruled on any disputes. With the game being broadcast live, Magnus had just one minute of thinking time to make his move. A game operator would then input this move into a computer, revealing it to the three grandmasters and the online audience. The trio then had one minute to make their suggested response. The online viewing public then had a minute and a half to place their votes. You certainly didn't want to have your internet connection fail during this. The computer tallied the votes and the most popular move was made on the board in the penthouse. If all three grandmasters proposed the same move, however, it would be made automatically. Now, those were the easy rules. The following were the tricky ones. Both Carlsen and the grandmasters were allowed three 'extra time' periods, which granted an additional two minutes of thinking time. If any grandmaster did not suggest a move within a minute, an extra time period was used up. If all three of the periods had already been used up, however, they lost. The same applied to Carlsen. In the case of a draw offer, the three grandmasters discussed it verbally, with the majority rule deciding whether they accepted or not. If two or all three of the grandmasters' suggested moves received exactly the same percentage of votes, the move with the greater physical count number was played. In the event that two or all three of the suggested moves received exactly the same number of votes, the move that reached the vote number first was played. However, few were really overly interested in the more complex rules, and wanted to see what would unfold over the course of the day.
