It seems that the worlds leading players have been put to work by some kind of higher power. Today sees the start of the Pearl Spring tournament in Nanjing, a week after the Grand Slam final in Bilbao was completed. Backing up from that event are Carlsen and Anand, while Carlsen(!), Topalov, Yue, and Bacrot played in the Olympiad less than 3 weeks ago. The only player who is completely rested is Vugar Gashimov, although his rest from the Olympiad was not of his choosing.
As the event is being held in China, the games are being played in the early evening, Canberra time. This means a visit to http://www.chess-pearlspring.com/www/chess_pk/2009/en/ will give you the live broadcast of the games, along with other info (NB Ignore the 2009 in the URL, the link covers the 2010 tournament). The only decisive game of the first round was a win by Carlsen over Bacrot, with the other 4 players taking a half.
Who do I think will win? I'm going to go with my usual pick for these sort of events and say Carlsen, especially given the confidence boosting first round win. Second may well be Topalov, with Anand playing a little more conservatively post Bilbao.
